Halting the Entire Cluster

You can use Serviceguard Manager, or Serviceguard commands to halt a

running cluster.

Using Serviceguard Manager to Halt the Cluster

Select the cluster, then right-click to display the action menu. Select

“Halt cluster

.” The progress window shows messages as

the action takes place. This will include messages for halting each

package and node. Click OK on the progress window when the operation

is complete.

Using Serviceguard Commands to Halt a Cluster

The cmhaltcl command can be used to halt the entire cluster. This

command causes all nodes in a configured cluster to halt their

Serviceguard daemons. You can use the -f option to force the cluster to

halt even when packages are running. This command can be issued from

any running node. Example:

# cmhaltcl -f -v

This halts all nodes that are configured in the cluster.

Automatically Restarting the Cluster

You can configure your cluster to automatically restart after an event,

such as a long-term power failure, which brought down all nodes in the

cluster. This is done by setting AUTOSTART_CMCLD to 1 in the

/etc/rc.config.d/cmcluster file.
