Notes
• After a device group is configured in the resource configuration utility, do not change the device
group name or swap the name with another device group name in the HORCM file. If you do this,
restart the HORCM manager instance and reconfigure the XP Cluster Extension resource.
• Do not use HORCM commands to change the device group property for a device group that is
configured for an XP Cluster Extension resource. If you do this, the changed property is not reflected
immediately in the Parameters tab. To work around this situation, re-select the device group from
the XP RM device group menu in the Parameters tab.
