Troubleshooting Cluster Start and Restart

This section provides the following information about troubleshooting problems that you might encounter with starting and restarting the Geographic Edition software:

• Validating Protection Groups in an Error State

• Restarting the Common Agent Container

• Matching the Nodelist Property of a Protection Group to Those of Its Device Group and Resource Group

Validating Protection Groups in an Error State

After a cluster reboot the protection group configuration might be in an error state. This problem might be caused by the common agent container process not being available on one of the nodes of the cluster when the protection group is initialized after the reboot.

Solution or Workaround

To fix the configuration error, use the geopg validate command on the protection group that is in an error state.

Restarting the Common Agent Container

The Oracle Solaris Cluster software enables the common agent container only during the Oracle Solaris Cluster software installation. Therefore, if you disable the common agent container at any time after the installation, the common agent container remains disabled.

Solution or Workaround

To enable the common agent container after a node reboot, use the /usr/lib/cacao/bin/cacaoadm enable command.

Matching the Nodelist Property of a Protection Group to Those of Its Device Group and Resource Group

When you add resource groups, or Availability Suite device groups to a protection group, or when you run the command geopg get on a protection group, the order of the hosts in the nodelist property of each device group and resource group in the protection group must match the order of the hosts in the nodelist property of the protection group, or the operation will fail with a message similar to:

Application resource group app-rg must have a nodelist whose physical host components match those 
of protection group app-pg and the resources it contains.

The Geographic Edition software requires that the entries in the nodelist property of a Availability Suite protection group match those of any device group or resource group added to the protection group. The order of the entries in their nodelist properties must also be identical.

Solution or Workaround

Ensure that the entries, and the order of the entries in the nodelist properties of a protection group, of its device groups, and of its resource groups are identical.
