Replacing a disk drive or solid-state drive in the 8248-L4T,
8408-E8D, or 9109-RMD
Learn how to replace a small computer system interface (SCSI) or serial-attached SCSI (SAS) disk drive or
solid-state drive in the system or expansion unit with the system power turned on or off.
To remove and replace a disk drive or solid-state drive in a different enclosure, use the information for
that enclosure.
Use this procedure to remove a failed disk drive or solid-state drive and replace it with the same type of
disk drive or solid-state drive. If you plan to remove a disk drive or solid-state drive and install a
different type of disk drive or solid-state drive, remove the existing disk drive or solid-state drive.
The system or logical partition can be turned off or turned on when you replace the disk drive or
solid-state drive. If the disk drive or solid-state drive that is being replaced is in the AIX, IBM i, or Linux
root volume group (rootvg) and does not have disk protection, or if it is a PCI Express (PCIe) RAID
adapter with integrated solid-state disk drives, then replace the disk drive or solid-state drive by using
the procedure for replacing with the power turned off.

Removing and replacing a disk drive in the 5887 disk drive enclosure unit
Replacing a disk drive or solid-state drive in the 8248-L4T, 8408-E8D,
or 9109-RMD with the AIX system or logical partition power turned on
Learn to replace a failed Small Computer System Interface (SCSI) or serial-attached SCSI (SAS) drive in a
system or an expansion unit while the power to the AIX operating system or logical partition that
controls the drive location is turned on.
To replace a drive, you must first ensure that the slot it will occupy does not contain another drive or a
disk-drive filler. For the procedure to remove a drive, see "Removing a disk drive or solid-state drive
from the 8248-L4T, 8408-E8D, or 9109-RMD with the AIX system or logical partition power turned on" on
page 29. For the procedure to remove a disk-drive filler, see "Removing a disk drive filler from the
8248-L4T, 8408-E8D, or 9109-RMD" on page 75.
Attention:
Review the following information to determine whether your situation requires a different
procedure to be performed instead of this one:
v If the drive that you are replacing is in the root volume group (rootvg) and it is not protected by either
Redundant Array of Independent Disks (RAID) or mirroring, or to use the powered-off procedure, go
to "Replacing a disk drive or solid-state drive in the 8248-L4T, 8408-E8D, or 9109-RMD with the system
or logical partition power turned off" on page 70.
v If you are installing a new or upgraded drive, see "Installing a disk drive or solid-state drive in the
8248-L4T, 8408-E8D, or 9109-RMD with the AIX system or logical partition power turned on" on page
5.
If you are replacing a drive as part of a service procedure, continue to use the following procedure.
Note: Some of the figures in these procedures might not look exactly like the system or expansion unit
that you have. However, the steps to complete the task are the same.
