Manage HP Service Guard on Linux clusters

Note : The Linux clusters have two cluster nodes running RHEL or SLES with one or more Service guard packages, each with shared file systems and VIP.

1) Start the cluster.

To start the cluster, use the following command. This command will start each of the nodes in the cluster as well as the Data Protector package:
# cmruncl

2) Stop the cluster.

To shut down the cluster, use the following command:
# cmhaltcl –f
The -f option will shut down the package running on the cluster and then all the cluster nodes.

3) Check the cluster logs.

All the cluster events (except the specifics events for packages) are tracked in the system logs. You can check the latest cluster events by using the following command:
# tail -f /var/ log/messages

4) Check the cluster status.

Use the following commands to check the cluster status. Both cluster nodes should be up and running, the package should be running in the primary node and both AUTO_RUN and switching should be enabled in both nodes:
# cmviewcl
# cmviewcl –v
