Check volume redundancy

Under the guidance of technical support or as instructed by the Recovery Guru, you can check the redundancy on a volume in a pool or volume group to determine whether the data on that volume is consistent. Redundancy data is used to quickly reconstruct information on a replacement drive if one of the drives in the pool or volume group fails.

Before you begin

Note: Check volume redundancy only when instructed to do so by the Recovery Guru and under the guidance of technical support.

About this task

You can perform this check only on one pool or volume group at a time. A volume redundancy check performs the following actions:

Note: Immediately running a redundancy check on the same pool or volume group might cause an error. To avoid this problem, wait one to two minutes before running another redundancy check on the same pool or volume group.

Procedure

  1. Select Storage > Pools & Volume Groups.
  2. Select Uncommon Tasks > Check volume redundancy.
    The Check Redundancy dialog box appears.
  3. Select the volumes you want to check, and then type check to confirm you want to perform this operation.
  4. Click Check.

    The check volume redundancy operation starts. The volumes in the pool or volume group are sequentially scanned, starting from the top of the table in the dialog box. These actions occur as each volume is scanned:

    • The volume is selected in the volume table.
    • The status of the redundancy check is shown in the Status column.
    • The check stops on any media or parity error encountered, and then reports the error.
  5. Click Done after the last volume in the pool or volume group has been checked.
