2. When the cluster has started, make sure that cluster components are
operating correctly:
cmviewcl -v
Make sure that all nodes and networks are functioning as expected.
For more information, refer to the chapter on “Cluster and Package
Maintenance.”
3. Verify that nodes leave and enter the cluster as expected using the
following steps:
• Halt the cluster. You can use Serviceguard Manager or the
cmhaltnode command.
• Check the cluster membership on the map or tree to verify that
the node has left the cluster. You can use Serviceguard Manager
or the cmviewcl command.
• Start the node. You can use Serviceguard Manager or the
cmrunnode command.
• Verify that the node has returned to operation. You can use
Serviceguard Manager or the cmviewcl command again.
4. Bring down the cluster. You can use Serviceguard Manager or the
cmhaltcl -v -f command.
Additional cluster testing is described in Chapter 8, “Troubleshooting
Your Cluster,” on page 299. See Appendix A, “Serviceguard Commands,”
on page 323 for a complete list of Serviceguard commands. Use the
Serviceguard Manager Help for a list of Serviceguard administrative
commands.
