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.

Adding a disk drive as a resource by using AIX

After replacing or installing a disk drive, use this procedure to have the system add the disk drive as a
resource.
After replacing or installing a disk drive, you must add the new disk drive as a resource. To add the disk
drive as a resource, do the following steps:
1. Press Enter.
The disk drive slot exits the Remove state and enters the Normal state.
2. Exit to the RAID Hot-Plug Devices menu. Press the F3 or simultaneously press Esc+3.
3. Exit to the Task selection display.
4. Select Log Repair Action.
5. Select the disk drive that you replaced and then press Enter.
6. Select Commit and then press Enter.
7. Exit to the command line.
8. Go to Verify a repair in your host server's service information. This completes this procedure.
Note: To rebuild data on the replacement disk drive, refer to the information for the controller to which
the disk drive is attached.
v If the disk drive is attached to a PCI-X SCSI RAID controller, see the PCI-X SCSI RAID Controller
Reference Guide for AIX.
v If the disk drive is attached to a PCI SCSI RAID adapter (feature code 2498), see the PCI 4-Channel
Ultra3 SCSI RAID Adapter Reference Guide.

Deactivating a disk drive by using Linux

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 Linux.
You must have the Linux 2.6 kernel installed.
1. Log in as root user.
2. Type iprconfig on the command line of the Linux session and press Enter.
The IBM Power RAID Configuration Utility opens.
3. Select Analyze log and press Enter. The Kernel Messages Log display is shown.
4. Select View most recent ipr error messages from the Kernel Messages Log display. Press Enter.
5. Find the entry in the log for the disk drive you want to deactivate.
6. Record the location information for the disk drive.
Note: The location information has the form of 2:0:8:0. In this example, 2 is the SCSI host number, 0
is the SCSI bus, 8 is the SCSI target ID, and 0 is the LUN (logical unit).
7. Return to the command line.
8. Type the following code phrase:
5786, 5787, 7031-D24, and 7031-T24 removal and replacement procedures
