Configuring a disk drive or solid-state drive on a load source adapter for hot spare by using the IBM i operating system

To start hot spare protection on your load source adapter you will need to determine the status of the disk drive or solid-state drive in the load source slot and configure or exchange that drive, which might require you to turn off the system power.

  1. If necessary, start System Service Tools (SST) by typing strsst on the command line of the IBM® i session and pressing Enter.
  2. Type your service tools user ID and service tools password on the Start Service Tools (STRSST) Sign On display. Press Enter.
    Note: The service tools password is case sensitive.
  3. Determine the protection status of all drives controlled by the load source adapter. Do all drives that are a member of a parity sets or mirror sets have a status of active?
    Restriction: There must be a drive of the same or larger capacity located in a load source capable slot to act as a hot spare for the active load source drive. The next steps will have you change the drive in the desired slot if needed.
    Attention: If the drive acting as hot spare for the load source is of smaller capacity you can suffer data loss.
  4. Determine whether a non-configured drive of the same or larger capacity is located in a load source capable slot but is not the active load source. Only parallel SCSI places a restriction on the location of the load source. Any SAS, Fibre Channel, or virtual drive does not have this restriction.
    • No non-configured drive is located in a load source capable slot. Continue with the next step
    • Yes a non-configured drive is located in a load source capable slot. Return to the procedure that sent you here, and continue to the next step of that procedure.
  5. Choose the drive to be installed or exchanged with the drive in the load source slot by doing the following:
    1. Select a drive in a parity set located in a load source capable slot, but is not the active load source drive, and record the location of this drive.
    2. Select a non-configured drive of the same or larger capacity from either a non-load source slot or a failed drive you are replacing with a non-configured drive.
  6. Stop the system if it is running. For instructions on stopping the system, see Stopping the system or logical partition.
  7. Exchange the drives from the two locations you recorded in step 5 by removing both drives and placing them into the other drives slot.
  8. Start the system. See Starting the system or logical partition.
  9. Return to the procedure that sent you here and continue with the next step in that procedure.
