Hot-Plug Disk Drive Replacement
Attention: Before you perform these procedures, ensure that the customer has taken appropriate
actions to back up the data for the drive you are removing, and that the drive has been removed from the
configuration. Physically removing a hot-plug drive from the system before it has been removed from the
system configuration can cause unrecoverable data corruption. Refer to “Deconfiguring (Removing) or
Configuring a Disk Drive” on page 470.
Do not use Install/Configure Devices Added After IPL if your system is set up to run HACMP clustering.
Consult with your system administrator or software support to determine the correct method to configure
the replacement disk.
To install a hot-plug disk drive, do the following:
1. Ensure the tray handle is open (perpendicular to the drive).
2. Align the drive/tray assembly so that it engages the guide rails in the bay.
3. Push the drive assembly into the bay until the tray handle engages the lock mechanism.
4. Push the tray handle in until it locks. The lit LED on the disk drive will turn on.
5. Log in as root user.
6. At the command line, type smitty.
7. Select Devices.
8. Select Install/Configure Devices Added After IPL and press Enter. Successful configuration is
indicated by the OK message displayed next to the Command field at the top of the screen.
9. Press F10 to exit smitty.
10. Replace the front bezel as described in “Front Bezel Replacement (Model 6C4)” on page 442 or “Disk
Drive Access Cover Replacement (Model 6E4)” on page 438.
11. On a Model 6C4, close the rack doors.
