• Always lower the leveling pads on the rack cabinet.
• Always install stabilizer brackets on the rack cabinet.
• To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest
devices in the bottom of the rack cabinet. Always install servers and optional devices starting
from the bottom of the rack cabinet.
• Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top
of rack-mounted devices.
• Each rack cabinet might have more than one power cord. Be sure to disconnect all power cords in
the rack cabinet when directed to disconnect power during servicing.
• Connect all devices installed in a rack cabinet to power devices installed in the same rack cabinet.
Do not plug a power cord from a device installed in one rack cabinet into a power device
installed in a different rack cabinet.
• An electrical outlet that is not correctly wired could place hazardous voltage on the metal parts of
the system or the devices that attach to the system. It is the responsibility of the customer to
ensure that the outlet is correctly wired and grounded to prevent an electrical shock.

Use the following general safety information for all rack mounted devices:
Safety and environmental notices vii
CAUTION:
• Do not install a unit in a rack where the internal rack ambient temperatures will exceed the
manufacturer’s recommended ambient temperature for all your rack-mounted devices.
• Do not install a unit in a rack where the air flow is compromised. Ensure that air flow is not
blocked or reduced on any side, front or back of a unit used for air flow through the unit.
• Consideration should be given to the connection of the equipment to the supply circuit so that
overloading of the circuits does not compromise the supply wiring or overcurrent protection. To
provide the correct power connection to a rack, refer to the rating labels located on the equipment
in the rack to determine the total power requirement of the supply circuit.
• (For sliding drawers): Do not pull out or install any drawer or feature if the rack stabilizer
brackets are not attached to the rack. Do not pull out more than one drawer at a time. The rack
might become unstable if you pull out more than one drawer at a time.
• (For fixed drawers): This drawer is a fixed drawer and must not be moved for servicing unless
specified by the manufacturer. Attempting to move the drawer partially or completely out of the
rack might cause the rack to become unstable or cause the drawer to fall out of the rack.

x Hardware Maintenance Guide
Chapter 1. Manager disk replacement
Overview
Regular maintenance procedures such as disk and appliance replacement differ between types (Manager,
Accesser®Appliance, Slicestor®Appliance, or Fileserver pools). Disk replacement procedures for each one
are described.
Attention: Disk replacement should be performed with a drive that is acquired by IBM. Using an
alternative drive voids the support warranty and can potentially corrupt the data on the system.
All appliances contain an operating system disk. Slicestor®Appliance can have a separate operating
system disk or the operating system that is stored on a partition of the first data disk.
Note: Appliance operating system disk failures incur appliance downtime. The requirements for
replacing operating system disks are as follows.
v Recovery USB media to reinstall operating system.
v Network access to the Manager application.
v At least as much capacity on the replacement disk as the failed disk.
See the Manager Device Monitor page on the Manager Web Interface for drive bay layout and status.
Manager disk backup
Before you replace Manager disks, back up the data. Regular automatic backups should be scheduled.
Follow the procedures in the "Backup and restore Manager" section of the IBM Manager Administration
Guide.
Replace RAID disks
Replacing one RAID disk
About this task
The appliance can remain powered on when you replace a single disk.
Procedure
1. Acquire a replacement disk by contacting customer solutions.
2. Click the Manager device link. A warning message is displayed: The manager device RAID disk is
operating in degraded mode.
3. Click Configure.
4. Make a note of the bay number that is listed as ONLINE, and replace the drive that is not listed. The
drive that is listed is the good drive.
Note: Event console displays a message similar to - The drive in bay 0 has caused an array to be
degraded.. The bay number of the bad drive can be taken from that event, too.
5. Replace the failed disk. Replacement disk rebuilds, stating Repairing local drive array. When the
new drive is attached, the event console displays messages, such as: The drive in bay 0 was
attached. The local drive in bay 0 is repairing.
Disk repair is complete when the Event Console displays the message Local drive array has been
repaired.
