IBM SG24-5131-00 User Manual

IBM Certification Study Guide  AIX HACMP

  • 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.
