Notes
• After a device/copy group is configured in the resource configuration utility, do not change
the device/copy group name or swap the name with another device/copy group name in
the HORCM file. If you do this, restart the HORCM manager instance and reconfigure the P9000
Cluster Extension resource.
• Do not use HORCM commands to change the device/copy group property for a device/copy
group that is configured for a P9000 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/copy group from the P9000 device/copy group menu in the Parameters
tab.
