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) a disk
drive" on page 339.
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.
Note: Do not use Install/Configure Devices Added After IPL if your system is set up to run
clustering. Instead, if clustered, you must always run the NAS command /opt/nas/bin/cfgmgr
outside of smit. Never execute the root cfgmgr command (which is what the Hot Plug Manager
option Install/Configure Devices Added After IPL uses). For more information, refer to the
NAS Gateway 500 Command Reference.
9. Press F10 to exit smitty.
10. Replace the front bezel as described in "Front bezel replacement" on page 315.
11. Close the rack doors.
