Deactivating a disk drive by using AIX

Concurrent maintenance can be accomplished on disk drives without removing power to either the enclosure or the server. Use the following procedure in conjunction with the removal and replacement procedures to concurrently remove or replace a disk drive using the AIX® operating system.

To deactivate the disk drive and disk drive slot and do concurrent maintenance on your disk drives, do the following steps:

1. Log in as root user or use CE Login.
2. At the command line, type diag and press Enter.
3. Press Enter to continue.
4. On the Function Selection display, select Task Selection.
5. Select Hot Plug Task.
6. Select RAID Hot Plug Devices.
7. Select the adapter that is connected to the array that contains the disk drive you want to deactivate and press Enter.
8. Select Commit.
9. On the Identify and Remove Resources display, select Identify.
10. Select the disk drive you want to remove and press Enter.

    The disk drive slot enters the Identify state. The concurrent maintenance light for the slot begins flashing. Verify that the flashing light corresponds to the location for the disk drive you want to deactivate, and press Enter.

    The disk drive slot exits the Identify state.

11. On the Identify and Remove Resources display, select Remove.

    A list of the disk drives that you can remove is displayed. If the disk drive is not displayed in the list, ask your system administrator to put the disk drive in the Failed state before continuing with this procedure. For information, see the system-management topics in the IBM® System p® and AIX Information Center at: http://publib.boulder.ibm.com/infocenter/pseries/v5r3

12. Select the disk drive you want to deactivate and press Enter.

    The disk drive slot enters the Remove state and power is removed from the slot. The concurrent maintenance light for the slot begins flashing rapidly.

13. If you are removing a disk drive from your system, go back to Disk drive and complete the disk drive hardware removal portion of this procedure.
