How to Remove a Node From All Disk Device Groups

Use this procedure to remove a cluster node from all disk device groups that list the node in their lists of potential primaries.

1. Become superuser on the node you want to remove as a potential primary of all disk device groups.

2. Determine the disk device group(s) of which the node to be removed is a member.

   Look for the node name in the Device group node list for each disk device group.

   # scconf -p | grep ¨Device group"

3. Are any of the disk device groups identified in Step 2 of the device group type SDS/SVM?

   • If yes, perform the procedures in How to Remove a Node From a Disk Device Group (Solstice DiskSuite/Solaris Volume Manager).

   • If no, go to Step 4.

4. Are any of the disk device groups identified in Step 2 of the device group type VxVM?

   • If yes, perform the procedures in How to Remove a Node From a Disk Device Group (VERITAS Volume Manager).

   • If no, go to Step 5.

5. Determine the raw disk device groups of which the node to be removed is a member.

   Note that the following command contains two “v”s in -pvv. The second “v” is needed to display raw disk device groups.

   # scconf -pvv | grep ¨Device group¨

6. Are any of the disk device groups listed in Step 5 of the device group types Disk, Local_Disk, or both?

   • If yes, perform the procedures in How to Remove a Node From a Raw Disk Device Group.

   • If no, go to Step 7.

7. Verify that the node has been removed from the potential primaries list of all disk device groups.

   The command returns nothing if the node is no longer listed as a potential primary of any disk device group.

   # scconf -pvv | grep ¨Device group¨ | grep nodename
