Prepare to remove a disk drive from a system or expansion unit controlled by AIX

Learn the actions you need to take to properly remove a disk drive.

Before removing a disk drive from a system or expansion unit that is controlled by AIX®, ensure that all data on that disk drive or the array that contains the drive is backed up and removed from the disk drive and that the disk drive is in the Defined state.

If the disk drive is attached to a PCI-X SCSI RAID controller, see the PCI-X SCSI RAID Controller Reference Guide for AIX. If the disk drive is attached to another controller, see the information for that controller or the AIX System Management Guide: Operating System and Devices. These guides are available at the System p® and AIX Information Center. (http://publib.boulder.ibm.com/infocenter/pseries/v5r3/index.jsp)
