2. Functions of the WebManager¶

This chapter describes the functions of the WebManager.

This chapter covers:

2.1. Starting up the WebManager¶

Accessing to the WebManager is required to create cluster configuration data. In this section, the overview of the WebManager is explained. After that, access to the WebManager. How to create cluster configuration data is explained.

Note

You cannot configure or display functions that have been added to or changed in versions later than EXPRESSCLUSTER X 4.0.

See also

For the system requirements of the WebManager, see the corresponding web page.

2.1.1. What is WebManager?¶

The WebManager is a function to start the Builder, set up the cluster, monitor the cluster status, start up and stop servers and groups, and collect cluster operation logs through a Web browser. The overview of the WebManager is shown in the following figures.

The WebManager in EXPRESSCLUSTER Server is configured to start up at the time when the operating system starts up.

Specify the floating IP address or virtual IP address for accessing WebManager for the URL when connecting from a Web browser of the management PC. These addresses are registered as the resources of the management group. When the management group does not exist, you can specify the address of one of servers configuring the cluster (fixed address allocated to the server) to connect management PC with the server. In this case, the WebManager cannot acquire the status of the cluster if the server to be connected is not working.

2.1.2. Setting up Java Runtime Environment¶

In order to access the WebManager, a Java Runtime Environment (JRE) must be installed on the browser in a management PC. For a Java Runtime environment whose operation has been verified, refer to the website.
If the JRE is not installed on the management PC, the browser might prompt you to install.
Make sure that the JRE version is supported by WebManager when determining whether to install it.
To install Java Plug-in on a browser, refer to the browser's help and the Java installation guide.
You have to add the Exception Site for Java on the machine connected to the WebManager. From Control Panel, open Java and add "URLs used to connect to the WebManager."

2.1.3. Starting the WebManager¶

The following procedure describes how to start the WebManager.

Start your Web browser.
Enter the actual IP address and port number of the server where the EXPRESSCLUSTER Server is installed in the Address bar of the browser.

Note

In Java Runtime Enviroment Version 9.0 or later, WebManager can be launched by using Java Web Start. When starting the Java WebManager, change "main.htm" of the URL above to "main.jnlp" and then enter the modified URL in the Address bar.

Example: http://10.0.0.11:29003/main.jnlp
The WebManager starts up.

When you click Execute, access restriction is canceled in the server with an error.

To perform mirror recovery, click the icon of the server for which the access restriction is canceled, perform access restriction, and then follow the procedures in "2.6.2. Recovering a mirror (forcefully)".

Note

When the Auto Mirror Recovery is enabled and one of the servers is operating normally, it is necessary to disable Auto Mirror Recovery in advance or suspend the mirror disk monitor resource or hybrid disk monitor resource so that Auto Mirror Recovery does not operate when the access restriction is canceled in the server that is abnormal.

2.7. Manually stopping and starting the WebManager¶

Once EXPRESSCLUSTER is installed, the WebManager automatically starts and stops along with the operating system.

If you wish to stop and start the WebManager specifically, just stop or start the service for the WebManager from the Services console of Administrative Tools.

2.8. When you do not want to use the WebManager¶

If you do not want to use the WebManager for security reasons, change the settings of Services of Management Tool of your OS or that of the Builder not to start the WebManager.
To specify the settings by using Service of Management Tool, change the Startup Type of the EXPRESSCLUSTER Manager service to Manual.
The WebManager can be configured on the WebManager tab in Cluster Properties of the Builder. For information on how to configure and apply the settings, see "3.11.9. WebManager tab".

2.9. Setting limitations on the connection and operation of the WebManager¶

The limitation in connection and operation of the WebManager can be configured in Cluster Properties in the Builder. For details, see "3.11.9. WebManager tab".

2.9.1. Type of limitation¶

There are two ways to set usage limitations:

Limiting the access by using client IP addresses
Limiting the operation by using a password

Limiting the access by using client IP addresses

This function limits the clients who can access the WebManager and operations on the WebManager by using client IP addresses.

Add IP addresses to IP Addresses of the Accessible Clients on the WebManager tab in Cluster Properties of the Builder. For details, see "3.11.9. WebManager tab".

When setting the limitation of the connection of the WebManager, if you attempt to access to the WebManager from the IP address that is not added to IP Addresses of the Accessible Clients, the following error messages are displayed.

Example: when using the Internet Explorer

When connecting to the WebManager from the client of which the operation is limited, WebManager becomes Reference only and is not able to switch to Operation Mode nor Verification mode.

The limitation by using a password

This function limits viewing and operations on the WebManager by using a password.

To configure this limitation: in Cluster Properties of the Builder, click the WebManager tab and then Control connection by using password. For details, see "3.11.9. WebManager tab".

Once password limitation of the WebManager is set, the following authorization dialog box is displayed when trying to access the WebManager by setting a password.

You can log on to the WebManager by selecting Operation Mode or Reference Only in Authorization and entering a correct password.

The authorization dialog box is not displayed when the password limitation is not configured (you can log on to the WebManager without authorization).

You cannot log on to the WebManager if you enter a wrong password three consecutive times.

When you log in with Reference Only selected for Permission, the WebManager is placed in reference mode. When you attempt to switch to operation mode, config mode, or verification mode in this status, the above authorization dialog is displayed, and you are requested to enter a password for Operation Mode.

Combination of the IP address and password

The operational limitations when using both IP addresses and passwords are the following:

Password limitation

(Operable mode)

Password limitation

(Reference only)

Password limitation

(Unable to operate/view (authorization failed))

Client IP address limitation

(Operable Mode)

Authorization cannot be selected.

2.10. Operating a cluster by using the WebManager¶

2.10.1. Cluster shutdown and cluster shutdown reboot¶

For information on how to perform cluster shutdown and cluster shutdown reboot from the WebManager, see "2.3.2. Operations from the WebManager".

2.10.2. Mirror disk resource and hybrid disk resource¶

For information on how to use the mirror disks, hybrid disk resources, and Mirror Disk Helper from the WebManager, see "Server object" in "2.3.2. Operations from the WebManager" and "Objects of mirror disk resource and hybrid disk resource" in "2.3.2. Operations from the WebManager".

2.10.3. Recovering servers¶

When Auto Return is set to Off on the Extension tab in Cluster Properties of the Builder, and a server is shut down or rebooted without using the cluster shutdown command, the server is started in the suspension (isolated) state. A server in this status does not run as a part of the cluster system. Thus, you need to return the server to the cluster system after you have finished the necessary maintenance work on the server. For more information on how to return a server to a cluster system by using the WebManager, see "Individual server objects" in "2.3.2. Operations from the WebManager".

2.10.4. Shutting down and rebooting an individual server¶

For information on how to shut down and reboot an individual server from the WebManager, see "Individual server objects" in "2.3.2. Operations from the WebManager".

2.10.5. Starting, stopping, and moving an individual group¶

For information on how to start, stop, and move an individual group from the WebManager, see "Individual group objects" in "2.3.2. Operations from the WebManager".

2.10.6. Starting and stopping a group resource¶

For information on how to start and stop a group resource from the WebManager, see "Individual group resource objects (except mirror disk resources and hybrid disk resources)" in "2.3.2. Operations from the WebManager".

2.10.7. Resuming, suspending, and stopping dummy failure of monitor resources¶

For information on how to resume, suspend, or stop dummy failure of a monitor resource from the WebManager, see "Individual group resource objects (except mirror disk resources and hybrid disk resources)" in "2.3.2. Operations from the WebManager".

2.10.8. Resuming, suspending, starting dummy failure, and stopping dummy failure of an individual monitor resource¶

For information on how to resume, suspend, start or stop dummy failure of a monitor resource from the WebManager, see "Individual group resource objects (except mirror disk resources and hybrid disk resources)" in "2.3.2. Operations from the WebManager".

2.11. Limitations of the WebManager¶

Information displayed by the WebManager does not always reflect the latest status. To acquire the latest information, click the Reload icon on the toolbar or Reload in the Tool menu.
If a server fails while the WebManager is acquiring information, the information acquisition fails, which may result in the failure to show some objects.
Wait for the next automatic update, or click the Reload icon on the toolbar or Reload in the Tool menu to reacquire the latest information.
The EXPRESSCLUSTER logs cannot be collected from two or more WebManager instances simultaneously.
If you work on the WebManager when no connectivity is established, it may take a while to regain control.
While the mouse pointer is the hourglass which indicates that the OS is processing something, moving the cursor outside the browser may return to the arrow icon even if the process is still underway.
If a proxy server is used, configure the proxy server so that the port number of the WebManager can be relayed.
When a reverse proxy server is used, the WebManager does not run normally.
When updating EXPRESSCLUSTER, close all running browsers. Clear the Java cache (not browser cache) and open browsers.
When updating Java, close all running browsers. Clear the Java cache (not browser cache) and open browsers
If the client PC to connect to WebManager uses Java(TM) Runtime Environment Version 8.0 Update 162 or later, and cannot be connected to the Internet, it may take time to start WebManager. This can be avoided by setting Execute Certificate Revocation Check to Not Check on Detailed Settings on the Java Control Panel. For details of how to set it, check the Java website.
Do not set the Reload Interval on the WebManager tab or less than 30 seconds. If you set it for less than 30 seconds, it may affect the performance of EXPRESSCLUSTER

3. Function of the Builder¶

This chapter provides information on functions of the EXPRESSCLUSTER X Builder.

This chapter covers:

3.1. Overview of the Builder¶

The Builder is a tool for creating and changing the cluster configuration data (config and/or script) for the EXPRESSCLUSTER Ver3.0 or later.

Note

You cannot configure or display functions that have been added to or changed in versions later than EXPRESSCLUSTER X 4.0.

There are two versions of the Builder; online version and offline version.

Online version

To start the Builder, click Config Mode on the View menu or select the config mode icon [] from the dropdown menu on the toolbar.

You can also directly connect to the server to create a cluster or change its configuration and distribute the cluster configuration data.
Offline version

With the offline version Builder, you can create or change the cluster configuration data on the machine which cannot connect to a server.

To distribute the cluster configuration data, you need to use the clpcfctrl command.

See also

For the system requirements of the Builder, see the corresponding web page.

Note

In this guide, Builder refers to both the online version of Builder, which runs in WebManager config mode, and the offline version of Builder, which runs on the management PC.

"Host name" used in this guide represents the short name that excludes the domain name from a frequently qualified domain name (FQDN).

3.1.1. Limitations of the Builder¶

The following products' cluster configuration data is not compatible.

A Builder other than that of EXPRESSCLUSTER X 4.0 for Windows

The Builder of the EXPRESSCLUSTER for Linux

The Builder of the EXPRESSCLUSTER for Windows Value Edition
Cluster configuration data created using a later version of this product cannot be used with this product.
Cluster configuration data of EXPRESSCLUSTER X1.0/2.0/2.1/3.0/3.1/X3.2/X3.3/4.0 for Linux can be used with this product.

You can use such data by clicking Import from the File menu in the Builder.

Apply the cluster configuration data that is being edited to the connected server. You can select this menu when you open a valid cluster configuration file.

The following conditions must be satisfied to apply the configuration file.

A server exists.
A LAN heartbeat resource of kernel mode exists.

Note

If this condition is not satisfied, connection to the other server will fail, so applying of the cluster configuration data fails. In this case, you can forcibly apply the cluster configuration data only to a server to which connection is possible. For details, see "Creating a cluster (clpcfctrl --push)" in "Creating a cluster and backing up configuration data (clpcfctrl command)" in " EXPRESSCLUSTER command reference" in the "Reference Guide".

Note

When using a hybrid disk resource, do not apply configuration information if any part of the server is stopped. If configuration information is applied in this state, an error will be detected in the control module of the hybrid disk resource, possibly causing the server to shut down.

The following message is displayed while applying the cluster configuration data. If the applying the data fails, take an action according to the error message, and apply the data again.

Message	Solution
The apply is completed successfully.	-
Changes applied successfully. Some services have been stopped in order to apply the changes. Use the following steps to resume the stopped services. <Necessary operation> Execute now ?	If you select Yes, indicated operation is carried out.
There is the disk information that is not configured. Are you sure you want automatic configuration?	Some GUID information of the volume is not configured. If you select Yes, automatic configuration is performed by determining the current GUID information from the derive letter.
There is the HBA information that is not configured. Are you sure you want automatic configuration?	The HBA information is not configured for the server where the information of HBA for accessing the shared disk was configured at the time of the installation. If you select Yes, the information configured at the time of the installation is inherited.
There is difference between the disk information in the configuration information and the disk information in the server. Are you sure you want automatic modification?	The combination between the GUID information of the volume and the drive letter does not match with the one on the actual servers. If you select Yes, automatic configuration is performed by determining the current GUID information from the derive letter.
The upload was stopped. There is one or more servers that cannot be connected to. To apply cluster configuration information forcibly, run the clpcfctrl command on the server.	Since there is a server that cannot be connected to exist in the cluster, applying the cluster configuration data has been canceled. Make sure that all the servers in the cluster have been started, and then apply the cluster configuration data. If you want to apply the cluster configuration data forcibly even though there is a server that cannot be connected in the cluster, see "Creating a cluster (clpcfctrl --push)" in "Creating a cluster and backing up configuration data (clpcfctrl command)" in " EXPRESSCLUSTER command reference" in the Reference Guide.
An error occurred when applying data to the cluster. Cfctrl (%0)	Since an error has occurred while performing processing, applying the cluster configuration data has been canceled. Apply the data again.
Checking the cluster configuration file failed. Check the following settings. Server Name, IP address for interconnect, IP address for Integrated WebManager	There are differences between the IP addresses included in the cluster configuration information and the IP addresses currently set to each server. Check correct IP addresses are set or not.

See also

If a server that cannot be connected exists in the cluster, the cluster configuration information cannot be applied from the Builder. In this case, by running the clpcfctrl command, you can forcibly apply the cluster configuration information only on the server that can be connected.

Follow the steps below to forcibly apply the cluster configuration data.

Save the cluster configuration data to an appropriate directory of the local disk from the Builder.

Example) Save the configuration data to C:\config
Save the cluster configuration data that you have saved on a server in the cluster.

Example) Save the data in C:\config that you have saved in step (1) in the C:\tmp directory on a server in the cluster.
Run the following command on the server where the cluster configuration data has been saved.
```
clpcfctrl --push -x "Directory where the cluster configuration data has been saved" --force
```
Example) Run the following command on the server where step (2) has been performed.
```
clpcfctrl --push -x "C:\tmp" --force
```

When the check box is selected

System resource information related to the CPU, memory, processes, and others is collected regularly while the cluster is running.

The collected system resource information is collected when the clplogcc command or WebManager collects logs.

Specify type 2 to collect the log by the clplogcc command; specify Pattern 2 to collect the log by the WebManager. For details on log collection, see "Collecting logs (clplogcc command)" in "EXPRESSCLUSTER command reference" in the Reference Guide; and "Collecting logs by using the WebManager" in "Functions of the WebManager" in this guide.

A disk area of 450 MB or more is required to store the resource information, depending on the system operating conditions such as the number of processes that are running.

When the check box is not selected

No system resource information is collected.

Disable Recovery Action Caused by Monitor Resource Failure

When the check box is selected

The recovery action is disabled when the monitor resource is error.

When the check box is not selected

The recovery action is enabled when the monitor resource is error.

Note

This recovery action suppression function is intended to suppress the recovery action due to the error detection of a monitor resource. This does not suppress the recovery action at the time of an activation error of a group resource.

This function is not enabled for the action at the time of the stall error detection of the disk RW monitor resource or at the time of a timeout of the user space monitor resource.

This option is not available for the message receive monitor resource.

Action at Group Resource Activation or Deactivation Stall

Specify the action to apply in the event of an activation/deactivation stall of a group resource.

Emergency shutdown

Shutdown the server on which a stall occurred.

Generate an intentional stop error

Intentionally cause a stop error (Panic) on the server on which a stall occurred.

No operation (Operates as an activity or deactivity failure)

Use this to perform recovery upon the detection of an activation/deactivation failure of a group resource. For details on the recovery operation, see "Recovery Operation tab" in "Resource Properties" in "Group resource details" in the "Reference Guide".

Note

If a stall occurs with "Nothing (handle a stall as an activation/deactivation failure)" specified, the effect on the group resources is undefined, so we do not recommend changing the setting to "Nothing (handle a stall as an activation/deactivation If you do specify "Nothing (handle a stall as an activation/deactivation failure)", set the recovery operation upon the detection of an activation/deactivation failure of a group resource as described below.

Activation/deactivation retry threshold: 0 (times)

Failover threshold: 0 (times)

Final action: Intentionally causing a stop error

If Stop the cluster service and shut down OS or Stop the cluster service and reboot OS is specified as the final action, it takes a considerable amount of time for the cluster service to stop.

Disable the Final Action when OS Stops Due to Failure Detection

Click Detail Config to set suppression of the final action which accompanies the OS stop caused by error detection.

Group Resource When Activation Failure Detected

If the final action caused by an activation error detection in a group resource accompanies the OS stop, the final action is suppressed if all other servers are stopped.

Group Resource When Deactivation Failure Detected

If the final action caused by a deactivation error detection in a group resource accompanies the OS stop, the final action is suppressed if all other servers are stopped.

Monitor Resource When Failure Detected

If the final action caused by an error detection in a monitor resource accompanies the OS stop, the final action is suppressed if all other servers are stopped.

Note

If errors were detected on multiple servers almost at the same time, and the final action was taken for those servers, the final action which accompanies the OS stop may be taken for all the servers even if the final action caused by an error detection in a monitor resource is set to be suppressed.

The message receive monitor resource does not become the target for which the final action caused by error detection is suppressed.

The following situations lead to an OS stop during the final action when an activation/deactivation error is detected in a group resource and during the final action when a monitor resource error is detected.

Stop the cluster service and shutdown OS

Stop the cluster service and reboot OS

Generate an intentional stop error

Disable Shutdown When Multi-Failover-Service Detected

Click Detail Config to suppress the shutdown of all servers upon detection of both-system activation.

Server Group Survives When Multi-Failover-Service Detected

Select one server. The shutdown of the server, which belongs to the server group selected when the both-system activation of the failover group was detected, is suppressed. When the both-system activation is detected among servers in the selected server group, both of the servers will be shut down. If you want to suppress the shutdown in this case, make the settings to disable shutdown when the following double activation is detected.

Server Survives When Multi-Failover-Service Detected

Select one server. The shutdown of the server, selected when the both-system activation of the failover group was detected, is suppressed.

If a server group to which shutdown is not executed when Multi-Failover is detected is set, it is possible to select only a server belonging to the set server group. If no server group is set, all the servers can be selected.

Important

Suppose that shutdown is suppressed upon the detection of both-system activation in an environment in which the mirror disk resource is used for setting automatic mirror recovery. In this case, automatic mirror copying starts when the server which is shut down upon the detection of both-system activation is re-started through the OS. Care is needed since this discards one piece of data from among that updated separately on the mirror disk of each server at both-system activation.

You need to select a server for which the data is to be protected when suppressing shutdown caused by the detection of both-system activation in an environment in which the mirror disk resource is used.

Note

When the both-system activation is detected, the group statuses will be inconsistent among the servers, and failover and failback operations will be able to fail.

If a group status mismatch occurs, the following alert log is output:

Type: Warning
Module name: rc
Event ID: 1104
Message: A mismatch in the group %1 status occurs between the servers.

To fix this problem, restart the group, execute a cluster reboot, restart all the servers on which the groups are not started, or restart the cluster services of all the servers on which the groups are not started.

The value from 1 through 24 can be specified.
Restart count is not reset if this parameter is omitted with the parameter /R specified.

/SCR¶

When this parameter is specified, the application or service is restarted by scripts. This parameter is optional.

The application or service is restarted by itself if this parameter is omitted with the parameter /R specified.

/FOV¶

Fails over groups when the restart count threshold is exceeded on the application or service monitoring. This parameter is optional.

Servers are shut down if this parameter is omitted with the parameter /M or /R specified.

/CNT <count>¶

A failover is not performed when the number of failovers already performed exceeds the count specified by this option. This is to avoid servers from repeating failing over endlessly. The number of failovers is counted for each server.
The value from 1 through 255 can be specified.
When omitted, 8 is specified.
The failover count is reset to 0 on a specific server when:

the normal status continues more than 1 hour

Remarks

This command can be used only in scripts.
Multiple parameters can be specified for a command that is passed to an executable file.
The figure below indicates operations performed when the application or service started by ARMLOAD fails.
1. The application or service is started by ARMLOAD
2. A failure occurs
3. Threshold check
4. When the threshold is not exceeded, the application or service is restarted by scripts.
  
  4-1: Stop script execution 4-2: Start script execution
5. When the threshold is exceeded, a failover occurs or a server shuts down
  
  5-1: Stop script execution 5-2: Fails over to another EXPRESSCLUSTER server

Notes

This command can be specified only in scripts.
When you start the application with GUIs without specifying an account, select Allow service to interact with desktop on the EXPRESSCLUSTER Server service. When not selected, GUIs of the application are not displayed.
When you specify a user account, it should have "local logon" permission. For information on the user permissions, see the help of the domain user administrator.

When you specify the domain of an account explicitly, specify the following. Note that the domain name and the user name should be within 15 characters.
- When the account is a local administrator
```
armload watchid /u administrator ap.exe
```
- When the account is a domainadministrator
```
armload watchid /u domain\administrator ap.exe
```
When you use the monitoring function (/M option) of the ARMLOAD command, make the setting so that the debugger is not automatically started, nor monitoring processing is prevented.
Applications not suitable for ARMLOAD monitoring function

The applications whose processes do not stay resident persistently are not suitable for the process monitoring (*). Since the process monitoring is assumed to monitor processes that stay persistently and do not terminate by themselves, it determines that an error occurs on an application when the started process is terminated.

(*) The following applications are examples:

An application whose process started by ARMLOAD does not stay resident persistently

An application whose process started by ARMLOAD starts its child process, and the process started first does not stay resident persistently (ARMLOAD only monitors the process it started)
The application that requires GUIs may be terminated when it is started by the ARMLOAD command and logged off. To prevent the application from being terminated, start it with an account (/U option).
If you use this command with the [/U] option and any account other than built-in Administrator, the command might fail.
If you use this command with the [/S] option, it is recommended to set the recovery operation not to be performed by the service control manager so that applications other than EXPRESSCLUSTER will not control services.

If a service is set to restart upon the recovery operation by the service control manager, an unexpected action might be performed due to duplication with the recovery operation by EXPRESSCLUSTER.

Limitations

The ARMLOAD command with an account cannot be used in a batch program that is run with an account.
The application that is run with an account (including a child process) cannot use the LogonUser() function.
Do not execute a 16-bits application since it cannot be terminated by the ARMKILL command.
When including spaces in a parameter, enclose it in quotation marks.

Example) ARMLOAD Wid1 "\Program Files\Application.exe"
Only the process that is started by the ARMLOAD command can be terminated by the ARMKILL command.
Do not run the applications (XXXX.EXE) that EXPRESSCLUSTER provide.

The ARMLOAD command may terminate abnormally (return value 1: Cannot start the target application or service) if the application with an account is started while it cannot access the domain controller (due to a failed server or network disconnection, etc.).

4.7. Terminating the application or service (armkill command)¶

the armkill exe command terminates the application or service.

Command line: armkill.exe watchID [/C | /T time]

Description: This command terminates the application or service that was started up by the ARMLOAD command.

When one service is operated (monitoring target) with several ARMLOAD commands (when several ARMLOAD commands with /A option operate one service), the service is not terminated until ARMKILL is run for all watchID.

Parameter

<watchID>¶: Specifies the monitoring ID of the application or service you want to terminate.

Use the ID specified when the application or service was started up by the ARMLOAD command.

/C¶: Cancels the monitoring of the application or service but does not terminate the application or service.

This parameter is optional. When omitted, the application or service is terminated. This parameter cannot be specified with the /T parameter.

Do not use this option when stopping an application that was started by specifying the /U option of the ARMLOAD command.

/T <time>¶: Sets the termination wait time of the application or service.

The range that can be specified is from 0 to 3600 seconds. If 0 is specified, the command waits for the completion of termination of the application or service endlessly. This parameter is optional. When omitted, the wait time is set to 40 seconds. This parameter cannot be specified with the /C parameter.

Return Value

0	Success (the target application or service was terminated).
1	The application or service has already been terminated.
2	The application or service was not terminated. (The application or service is being terminated.)
8	The EXPRESSCLUSTER Server service has not been started.
9	The parameter is invalid.

Remarks

This command can be specified only in scripts.
To terminate the application, this command sends the WM_CLOSE message to it. If the application does not terminate within the specified time (/T time), this command executes the TerminateProcess() for the target application to forcibly terminate the application process.
To terminate the service, the requirement to stop the service is sent to the service control manager (SCM). When terminating the service has not been completed within the specified time (/T time), the return value of 2 is returned.
If /C is specified on this command, the application or service cannot be terminated by ARMKILL.

4.8. Waiting for the start or stop of groups (armgwait command)¶

the armgwait.exe command waits for the start or stop of groups.

Command line: armgwait.exe group_name [time-out] [/stop]

Description: This command waits for the start or stop of groups.

This command waits until the status of a group becomes active (when waiting for activation) or inactive (when waiting for termination), or until the specified time is exceeded.

Parameter

<group_name>¶: Specifies a name of the group whose completion of start or stop the command waits for.

<time-out>¶: Specifies the time-out by the second.

When this parameter is omitted, the time-out value is set to default (120 seconds).

/stop¶: Waits until the group is terminated.

When this parameter is omitted, this command waits for the startup of the group.

Return Value

0	The status of the failover group is active or inactive.
1	The time-out has elapsed.
7	The EXPRESSCLUSTER Server service has not been started.
8	The specified group does not exist.
9	The parameter is invalid.

Notes: Do not run this command directly from the start or stop script. When using this command from those scripts, prepare the batch file on which the command is described, and then run the batch file on the start or stop script by writing "START batch_file_name" on it.

Remarks: This command can be run only in scripts. Follow the process on Note when using this command on the start or stop script.

4.9. Exclusive control between servers command (armcall command)¶

the armcall.exe command runs commands or programs exclusively on nodes.

Command line: armcall.exe [/L lockname ] exec_name [parameter ...]

Description: This command executes a program from a script without terminating it, and returns the control to the script that is invoked again. This program is executed exclusively between nodes.

Parameter

/L <lockname>¶: Specifies the lock name. When this option is omitted, "Default" is specified for the name.

The commands are run exclusively for each lock name specified by this parameter.

<exec_name>¶: Specifies the command or program to be run.

<parameter...>¶: Specifies the command line information required to run the program specified in exec_name.

Return Value

0	Success
8	The program was not run due to an error.
9	The parameter is invalid.

Remarks: This command can be run only in scripts.

Examples: When the process <A> must be run on all nodes, and the running of process <A> must be exclusive between nodes:

When the process <A> should be run only on one node and the process <B> should be run at all nodes, and the process <B> must be started after the completion of the process <A>.

4.10. Retrieving the cluster wide variable or local variable (armgetcd command)¶

the armgetcd.exe command retrieves the cluster wide variable or local variable.

Command line: armgetcd.exe [/C] variable

Description: This command retrieves the setting value of the cluster wide variable or local variable specified by the armsetcd command.

Parameter

/C¶: Retrieves the setting value of the cluster wide variable. When this parameter is omitted, the value of the local variable is retrieved.

<variable>¶: Specifies the variable name set by the armsetcd command.

Return Value

0	The value could not be retrieved due to an error.
1-255	The value set by the armsetcd command is returned.

Remarks: This command can be specified only in scripts.

If you specify the variable name which is not set by the armsetcd command, 0 is returned.

4.11. Setting the cluster wide variable or local variable (armsetcd command)¶

The armsetcd.exe sets the cluster wide variable or local wide variable.

Command line: armsetcd.exe [/C] variable value

Description: This command sets the cluster wide variable or the local variable.

The setting value of the variable set by this command can be referred by using the armgetcd command on the same or other scripts.

The cluster wide variable is shared between servers in a cluster. The variable set by the armsetcd command on one server can be referred or changed on another server.

The local variable is valid only on the server on which the armsetcd command is run.

Parameter

/C¶: Sets the variable as a cluster wide variable.

When this parameter is omitted, the variable is set as a local variable.

<variable>¶: Specifies the name of the variable to be set. Specify the name with up to 127 alphanumeric characters.

(The name is case-sensitive.)

<value>¶: Specifies the value to be set to the variable on variable in integers from 1 through 255.

Return Value

0	Success
8	The variable was not set due to an error.
9	The parameter is invalid.

Remarks: This command can be run only in scripts.

Variable names are controlled separately for the cluster wide variable and the local variable. Thus, you can set both variables with one variable name. In this case, those are operated as two different variables.

The local variable is valid until the EXPRESSCLUSTER Server service of the server on which this command was run is terminated.

The cluster wide variable is valid until the EXPRESSCLUSTER Server services of all servers in a cluster are terminated.

4.12. Monitoring errors on the connection to the shared resources (armwhshr command)¶

the armwhshr.exe command monitors errors on the connection to the shared name.

Command line: armwhshr.exe share-name ip-addr [/INT time] [/LOG log-strings] [/PROC exec-name parameter-1 parameter-2 ... parameter-n]

Description: This command monitors errors on the connection to the shared name.

It checks if the ping is reached to the specified shared name server or monitors the connection error to the shared name. It registers the event log (ID:3514) when the ping is reached normally and an error occurred while connecting to the shared name.

However, the event log is not registered when the connection error is already detected. It is registered when the status of connection changes from normal to error.

With options, this command sends messages to the WebManager and starts specified executable files.

Parameter

<share-name>¶: Specifies a shared name (UNC name).

<ip-addr>¶: Specifies the IP address of a server that possesses shared name.

/INT <time>¶: Specifies monitoring interval (by the second).

The range which can be specified is from 30 through 86400. This parameter is optional.

When omitted, 180 (sec) is set for the interval.

/LOG <log-strings>¶: Specifies the character string to be reported to the WebManager when an error occurs on the connection to a shared name. It is reported to the WebManager every time an error on the connection to the shared name is detected. Maximum of 111 bytes can be specified for the string. If the string includes spaces, enclose it in double quotation marks. When you use the double quotation marks in the strings, describe them with \ ("). This parameter is optional.

/PROC <exec-name>¶: Specifies the name of an executable file that is started when an error occurs on the connection to the shared name. The executable file is started when the status of shared name connection changes from normal to abnormal. This parameter is optional.

<parameter-n>¶: This parameter is passed to the executable file. This parameter is optional.

Return Value

0	Success
1	The parameter is invalid.
2	Insufficient memory
8	The EXPRESSCLUSTER Server service has not been started.

How to use

When using the ARMWHSHR command, configure the following settings.

Registering the user account

Register the user account with an administrator right.
Describing the ARMWHSHR command in scripts

Create a new failover group for monitoring errors on the connection to the shared name(*), and describe the ARMWHSHR command in scripts.

* Setting a failover group
Add only one server to the Servers that can run the Group by clicking the Startup Server tab on the Group Properties.

For example, to monitor errors on the connection to the shared name (temp) of the server (server name: server public LAN IP address: 100.100.100.1), describe the following in the start script:

(Lines in the script that is run when CLP_EVENT is START)
ARMLOAD watchID /U Administrator ARMWHSHR \\server\temp 100.100.100.1
Describe the following in the stop script

(Lines in the script that is run when CLP_EVENT is START)
ARMKILL watchID

Usage example

This command is used to confirm whether the local disk of the server can be accessed from the network. On the cluster system with 2 servers, accessibility to local disks on both servers from the network can be checked by monitoring another server from both servers. The following indicates the examples of configuration and script descriptions.

Example

Server Information:

	Server1	Server2
Server name	server1	server2
Public LAN IP address	100.100.100.1	100.100.100.2
Shared name	(1)share1	(1)share2
	(2)share3

Script example

Start.bat of Server 1

IF "%CLP_EVENT%" == "START" GOTO NORMAL
GOTO EXIT
:NORMAL
ARMLOAD W1 /U Administrator ARMWHSHR \\server2\share2 100.100.100.2
:EXIT
EXIT

Stop.bat of Server 1
```
ARMKILL W1
EXIT
```

Start.bat of Server 2

IF "%ARMS_EVENT%" == "START" GOTO NORMAL
GOTO EXIT
:NORMAL
ARMLOAD W2 /U Administrator ARMWHSHR \\server1\share1 100.100.100.1
ARMLOAD W3 /U Administrator ARMWHSHR \\server1\share3 100.100.100.1
:EXIT
EXIT

Stop.bat of Server 2
```
ARMKILL W2
ARMKILL W3
EXIT
```

Notes: This command can be specified only in scripts.

4.13. Controlling the applications or services started by the armload command (EXPRESSCLUSTER Task Manager)¶

the armaswth.exe command lists applications or services started by the armload command in GUI.

Command line: armaswth.exe

Description: This command lists the applications or services started by the armload command in GUI. In addition, it can start or stop the applications or services, and suspend or resume the monitoring in the same way as the armload command.

Remarks: This command can be specified both in and outside scripts.

Sort: Click any of Application/Service Name, Failover Group Name, WatchID, Type, Running Status, or Monitoring Status to sort the list into ascending or descending order of the clicked item.

Operation

Same as the ARMLOADC command, four operations of monitoring stop, monitoring resume, stop, start can be performed. Operations that can be performed vary depending on the status of the application or service start and the monitoring. For details, see "ARMLOADC command."

Select the application on the list (you cannot select multiple applications), and operate it by one of the following ways:

Operation menu
Toolbar
Shortcut menu displayed by right-clicking the application name (shown below)

Settings

To configure the settings, click Settings on the Option menu or on the toolbar.

Update Interval of Application/Service List: Specify the interval to automatically update the application or service list by the second. The value from 0 through 3600 can be specified. When 0 is set, the list is not updated automatically. The default is 10 (seconds).

Timeout to stop Application/Service: Specify the wait time to stop when stopping the application or service by the second. The value from 0 through 3600 can be specified. When 0 is set, the termination of the application or service is waited endlessly. The default is 40 (seconds). If the application or service is not stopped after the stop time is exceeded, the application is forcibly stopped. This setting is used only when the application or service is stopped by the EXPRESSCLUSTER Task Manager.

4.14. Shutting down the server (armdown command)¶

the armdown.exe command shuts down the server.

Command line: armdown.exe [reboot | off | stop]
