Listing quorum disks using the CLI

You can use the command-line interface (CLI) to list the managed disks (MDisks) currently defined as quorum disks.

1. Issue the following CLI command:

   svcinfo lsquorum -delim :

   The following output is an example of what you might see when you issue the svcinfo lsmdisk ­delim : command:

   quorum_index:status:id:name:controller_id:controller_name:active
   0 online 987 mdisk78 5 DS8K no
   1 online 2001 mdisk1 2 DS4K-1 no
   2 online 309 mdisk9 1 IBM-3 yes

2. View the active column to determine the whether the MDisk is the active quorum disk. The value Yes indicates that the MDisk is the active quorum disk, which means that it is the first disk that is used in the event of a cluster partition. You can set an active quorum disk when nodes in an I/O group are split between different physical locations to ensure that the most highly-available quorum disk is used. To set the active quorum disk, use the -active parameter on the setquorum command.
3. You can also list more detailed information about an MDisk. For example, issue the svcinfo lsquorum -delim : 2 command to see detailed information about the quorum disk with a quorum index of 2. The following output is an example of what you might see:

   quorum_index:2
   status:online
   id:309
   name:mdisk9
   controller_id:1
   controller_name:IBM-3
   active:yes
