Preparing to remove a disk drive or solid-state drive from a system or an expansion unit controlled by AIX

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

If the drive is attached to a SAS RAID controller, see SAS RAID controllers for AIX. If the drive is attached to a PCI-X SCSI RAID controller, see the PCI-X SCSI RAID Controller Reference Guide for AIX or SAS RAID controllers for AIX topic. If the 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.
