ProcedureHow to Enable a Component in a RAID-5 Volume

If a disk drive is defective, you can replace it with another available disk (and its slices) on the system as documented in How to Replace a Component in a RAID-5 Volume. Alternatively, you can repair the disk, label it, and run the metareplace command with the -e option to re-enable the disk.

  1. Make sure that you have a current backup of all data and that you have superuser access.

  2. To enable a failed component in a RAID-5 volume, use one of the following methods:

    • From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node, then open the RAID-5 volume. Choose the Components pane. Then, choose the failed component. Click Enable Component. Follow the onscreen instructions. For more information, see the online help.

    • Use the following form of the metareplace command:

      # metareplace -e volume-name component-name

      Specifies to place the failed component into an available state and to perform a resynchronization on the failed component.


      Specifies the name of the volume containing the failed component.


      Specifies the name of the failed component.

      The metareplace command automatically starts resynchronizing the new component with the rest of the RAID-5 volume.

Example 15–4 Enabling a Component in a RAID-5 Volume

In the following example, the RAID-5 volume d20 has a slice, c2t0d0s2, which had a soft error. The metareplace command with the -e option enables the slice.

# metareplace -e d20 c2t0d0s2
