Hot-Plug Disk Drives
Before performing the following procedure, read "Safety Notices" on page vii.
Attention:
The Linux operating system does not support these hot-pluggable procedures. A system with
Linux installed must be shut down and powered off before installing any disk drive or PCI adapter.
Note: You do not have to power off your AIX system to remove a hot-plug disk drive. Before you perform
these procedures, ensure that you have taken the 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 disk drive from the system before it has been removed from the system
configuration can cause unrecoverable data corruption.

Use these procedures if you are removing or installing a drive while the system power is turned on.
