Learn to replace a Small Computer System Interface (SCSI) or serial-attached SCSI (SAS) disk drive in
a system or expansion unit while the power of the Linux operating system
or logical partition that controls the disk drive location is turned
on.
If you are installing a new or upgraded disk drive, see Installing a disk drive or solid-state drive with the Linux system or logical partition power turned on.
If you are removing a disk drive as part of a service procedure, continue
to use the following procedure.
Attention: Read these instructions carefully and understand
the complexity of the powered-on procedure before you begin. If the
system or logical partition that controls the disk drive you are replacing
is at the Linux command
line, you can use this powered-on procedure.
Go
to Replacing a disk drive with the system or logical partition power turned off,
if:
- You are installing a disk drive that is to be connected with the
6203 or 6204 SCSI adapter.
- You do not feel comfortable using the powered-on 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 perform the task are the same.
Preparing the system
- Complete the prerequisite tasks.
For instructions, see Before you begin.
- Is the disk drive you are replacing in a redundant array
of independent disk (RAID) 0 array or is the disk drive you are replacing
in a failed RAID level 5 or 10 array?
- If the disk drive you are replacing is in a redundant array
of independent disk (RAID) Level 0 disk array or in a failed RAID
Level 5 or RAID Level 10 disk array, you must delete the disk array
before replacing the disk. For instructions, see the PCI-X
SCSI RAID Controller Reference Guide for Linux.
This
guide is available from the SCSI PCI Adapters web page.
- If applicable, remove the system unit door or expansion
unit door or open the rack front door.
- If applicable, remove the front cover.
- If you have a front cover from any other models, remove the front
cover.
Replace the disk drive by using the Linux kernel 2.6.
