Creating hot spare disks

Follow this procedure to create hot-spare disks.

Procedure

  1. Start the IBM® SAS Disk Array Manager by following the steps in Using the Disk Array Manager.
  2. Select Change/Show SAS pdisk Status.
  3. Select Create a Hot Spare.
  4. Select the appropriate controller.
  5. Select the pdisks that you want to designate as hot-spare disks.
    A screen summarizes your selections.
  6. Press Enter to create the hot spares.

What to do next

The disk state changes to Hot Spare. On subsequent disk failures, reconstruction of failed disks will occur automatically for RAID 5, 6, 10, 5T2, 6T2, and 10T2 disk arrays.
Note: If there is a degraded disk array at the time that a hot-spare disk is configured, reconstruction of the Failed disk begins automatically.
