Use this procedure to remove a Redundant Array of Independent
Disks (RAID) storage controller before installing a new or upgraded
storage controller. You can also use this procedure to remove a RAID-10
storage controller.
Identify the system that you will be working on by using
the identify the system process to turn on the system locate (blue)
indicator. For more information, see Control panel
LEDs.
Attention: To maintain system
availability and prevent possible data loss, it is important to understand
that these features have implications on the serial-attached SCSI
(SAS) configuration and data accessibility of the system. Review the
SAS
subsystem topic to understand the various
SAS configuration and service considerations.
Before servicing or installing any features,
review the I/O configurations for each logical partition on your system.
It is important to understand the differences between the various
configurations and the resulting service considerations. In addition,
consider possible impacts to the following areas:
- Logical partitions and their I/O adapter assignments
- RAID array configurations
- Physical disk locations
- Path to your boot device
If your system is managed by the
Hardware Management Console (
HMC), use the
HMC to remove RAID/cache
storage controller from the server. For instructions, see
Removing a part using the Hardware Management ConsoleIf your system is managed by the IBM® Systems Director Management Console (SDMC), use the SDMC to remove the RAID/cache
storage controller from the server. For instructions, see Removing a part using the Systems Director Management
Console.
If
you do not have an HMC or an SDMC,
complete the following steps to remove RAID/cache storage controller:
- Complete the prerequisite tasks.
For instructions, see Before you
begin.
- Stop the system. For instructions, see Stopping a system or logical
partition.
- Remove the front cover.
- For a rack-mounted system, place
the system into the service position, as described in Placing
a rack-mounted model into the service position.
- Remove the service access
cover.
- Use the service indicator light-emitting
diodes (LEDs) to help identify the part. For instructions, see Identifying a part.
- Disconnect the power source from
the system by unplugging the system.
Note: This system is optionally equipped with a second power
supply. Before continuing with this procedure, ensure that the power
source to the system has been completely disconnected.

- Attach the wrist strap.
Attention: - Attach a wrist strap to an unpainted metal surface of your hardware
to prevent electrostatic discharge (ESD) from damaging your hardware.
- When using a wrist strap, follow all electrical safety procedures.
A wrist strap is for static control. It does not increase or decrease
your risk of receiving electric shock when using or working on electrical
equipment.
- If you do not have a wrist strap, just prior to removing the product
from ESD packaging and installing or replacing hardware, touch an
unpainted metal surface of the system for a minimum of 5 seconds.
- Locate the RAID/cache storage controller that you want
to remove.
- Pull the tab (A) out and slide the
card (B) out of the system as shown in the
following figure.

To replace
the RAID/cache storage controller, see Replacing
the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C,
or 8205-E6D RAID/cache
storage controller.
