Task 2: Verify Availability Tools

Perform this task only if you have configured the system with improved availability of services.

HP recommends that you verify the successful operation of the availability tool. This section describes how to verify HP Serviceguard. If you configured an availability tool from another vendor, see the product documentation for information about how to verify successful operation of the tool.

Verifying HP Serviceguard

Enter the following commands to verify the installation and configuration of Serviceguard:

List the nodes that are members of availability sets:

# shownode config hostgroups
hostgroups:
headnode:               n16
serviceguard:avail1:    n14
                        n16

In this example, one availability set, avail1, has been configured.

On one node in each availability set, view the status of the Serviceguard cluster:

# pdsh -w n14 /usr/local/cmcluster/bin/cmviewcl




	NOTE: The `/usr/local/cmcluster/bin` directory is the default location of the cmviewcl command. If you installed Serviceguard in a location other than the default, look in the `/etc/cmcluster.conf` file for the location of the Serviceguard `bin` directory.

Successful command output is similar to the following:

CLUSTER      STATUS 
avail1       up 

 NODE         STATUS       STATE 
 n14          up           running 

   PACKAGE      STATUS       STATE        AUTO_RUN     NODE 
   nat.n14      up           running      enabled      n14 

 NODE         STATUS       STATE 
 n16          up           running 

   PACKAGE          STATUS       STATE        AUTO_RUN     NODE 
   nat.n16          up           running      enabled      n16 
   lvs.n16          up           running      enabled      n16 
   nagios.n16       up           running      enabled      n16 
   dbserver.n16     up           running      enabled      n16
