caa_stop(8)

NAME

caa_stop - Stops a Cluster Application Availability (CAA) application resource

SYNOPSIS

/usr/sbin/caa_stop resource_name [...] [-q] /usr/sbin/caa_stop resource_name [-f] [-q] /usr/sbin/caa_stop -c cluster_member [...] [-q] /usr/sbin/caa_stop -all [-q]

PARAMETER

resource_name [...] Name(s) (as specified in a resource profile) of one or more resources to be stopped.

OPTIONS

-c cluster_member [...] Specifies one or more active cluster members on which to stop all application resources. -all Stops all application resources on all active cluster members. -f (reserved for future use) -q Runs the caa_stop command in quiet mode; no messages are displayed on the console.

DESCRIPTION

The caa_stop command stops the indicated application resources that are running in a cluster. It calls the stop entry point in the resource's action script. If the stop fails, CAA marks the resource as "Suspended". You must run caa_stop on a suspended resource to mark its state as "Stopped" before you can restart it. The stop entry point of an application resource's action script is not called when a suspended resource is stopped. If a resource is marked as "Suspended" investigate why the stop entry point of the action script is failing. The caa_stop command displays progress on the command line. If there are troubles stopping an application, feedback will be displayed. If the CAA daemon is busy and cannot process the caa_stop request immediately, a message to this effect is displayed and the request is queued for processing once the daemon is free. These messages also appear as events in the EVM event management system. You must have root privilege to use this command. After a registered resource is started, you must use the caa_stop command to end execution of the specified resource in the cluster environment. You must not stop the resource independently of CAA.

EXAMPLES

1. The following example stops an application resource: /usr/sbin/caa_stop xclock Trying to stop `xclock` on `provolone` Successfully stopped `xclock` on `provolone` 2. The following example stops all resources on the specified cluster member: /usr/sbin/caa_stop -c provolone Trying to stop `xclock` on `provolone` Successfully stopped `xclock` on `provolone` Trying to stop `calc` on `provolone` Successfully stopped `calc` on `provolone`

EXIT VALUES

The following exit values are returned: 0 Successful completion non-zero A failure has occurred. A corresponding text message will be given for the following error conditions: No root privilege. CAA daemon is not running. Application is not running. Stop action script is not found.
