Halting the Entire Cluster
You can use Serviceguard Manager, or Serviceguard commands as shown
below, to halt a running cluster.
The cmhaltcl command can be used to halt the entire cluster. This
command causes all nodes in a configured cluster to halt their HP
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 the cluster nodes.
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
$SGAUTOSTART file (see “Understanding the Location of Serviceguard
Files” on page 140).
