•Shared volume groups

•List all volume groups in the cluster.

•Import a volume group (with HACMP 4.3 only).

•Extend a volume group (with HACMP 4.3 only).

•Reduce a volume group (with HACMP 4.3 only).

•Mirror a volume group (with HACMP 4.3 only).

•Unmirror a volume group (with HACMP 4.3 only).

•Synchronize volume group mirrors (with HACMP 4.3 only).

•Shared logical volumes

•List all logical volumes by volume group.

•Add a logical volume to a volume group (with HACMP 4.3 only).

•Make a copy of a logical volume.

•Remove a copy of a logical volume.

•Show the characteristics of a logical volume.

•Set the characteristics of a logical volume (name, size); this is only possible in non-concurrent mode and with HACMP 4.3.

•Remove a logical volume.

•Shared file systems (only applicable for non-concurrent VGs)

•List all shared file systems.

•Change/View the characteristics of a shared file system.

•Remove a shared file system.

C-SPOC has the following limitations:

•C-SPOC does not offer the option for creating volume groups. Use the TaskGuide or standard AIX commands.

•The new Volume Group must be imported manually to other nodes in the resource group (TaskGuide does it automatically).

•The Volume Group must be defined in a resource group, and cluster resources must be synchronized, prior to using C-SPOC to manage it.

•C-SPOC does not offer an option for creating file systems. Use standard AIX commands or SMIT menus to create file systems, and use C-SPOC to update the VG information on the other nodes.

•C-SPOC cannot be used for concurrent shared LVM components prior to HACMP 4.3 for AIX.
