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.
DANGER
When working on or around the system,
observe the following precautions:
Electrical voltage and current
from power, telephone, and communication cables are hazardous. To
avoid a shock hazard:
- Connect power to this unit only with the IBM provided
power cord. Do not use the IBM provided power
cord for any other product.
- Do not open or service any power supply assembly.
- Do not connect or disconnect any cables or perform installation,
maintenance, or reconfiguration of this product during an electrical
storm.
- The product might be equipped with multiple power cords. To remove
all hazardous voltages, disconnect all power cords.
- Connect all power cords to a properly wired and grounded electrical
outlet. Ensure that the outlet supplies proper voltage and phase
rotation according to the system rating plate.
- Connect any equipment that will be attached to this product to
properly wired outlets.
- When possible, use one hand only to connect or disconnect signal
cables.
- Never turn on any equipment when there is evidence of fire, water,
or structural damage.
- Disconnect the attached power cords, telecommunications systems,
networks, and modems before you open the device covers, unless instructed
otherwise in the installation and configuration procedures.
- Connect and disconnect cables as described in the following procedures
when installing, moving, or opening covers on this product or attached
devices.
To Disconnect:
- Turn off everything (unless instructed otherwise).
- Remove the power cords from the outlets.
- Remove the signal cables from the connectors.
- Remove all cables from the devices.
To Connect:
- Turn off everything (unless instructed otherwise).
- Attach all cables to the devices.
- Attach the signal cables to the connectors.
- Attach the power cords to the outlets.
- Turn on the devices.

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 power turned 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.
Remove the disk drive by using the Linux kernel 2.6.
