Removing Disks Using mrconfig

Suppose one of three disks in a storage pool has failed, and the storage pool has gone offline.

To remove a disk with mrconfig disk remove:

  1. Ensure that the data on the surviving disks is backed up/replicated.
  2. Remove the failed disk from the node's disktab with the mrconfig disk remove command.
  3. Physically remove the failed disk.
  4. Physically attach the replacement disk.
  5. Run the mrconfig disk init command on the replacement disk and on the other two disks that were in the disk group.
  6. Run the mrconfig disk load command on each of the three disks.
  7. Use the mrconfig dg create command to create a new disk group with the three disks.
  8. Use the mrconfig sp make command to create a storage pool on the new disk group.
