You might need to replace a Small Computer System Interface (SCSI) or serial-attached SCSI (SAS) disk drive in the server or expansion unit. Use the procedures in this section to perform this task.
To remove and replace a disk drive in a different enclosure, use the information for that enclosure.
Use this procedure to remove a failed disk drive and replace it with the same type of disk drive. If you plan to remove a disk drive and install a different type of disk drive, remove the existing disk drive as described in Removing a disk drive or solid-state drive, then install the new disk drive as described in Installing a disk drive or solid-state drive. If your system is managed by the Hardware Management Console (HMC), use the HMC to complete the steps for replacing a disk drive. For instructions, see Exchanging a part using the Hardware Management Console.
Your system or logical partition can be powered off or powered on when you replace the disk drive. If the disk drive that is being replaced is in the AIX® or Linux root volume group (rootvg) and does not have disk protection replace your disk with the powered-off procedure.
