5.4 Controller Maintenance
During the service life of the DVS system you may have to exchange a
RAID controller (see section “Introduction to RAID” on page 5-2). It
may be indicated, for example, if a disk set (RAID pack) cannot be ac-
cessed anymore. This section describes how to exchange a RAID con-
troller.
y
Identify the controller or disk set that causes the problem, for exam-
ple, by consulting the RAID software manager.
y
Then, open the casing of the system as described in section “Open-
ing the Casing” on page 5-7.
y
On the defective controller memorize the order of the cables that
are connected to it. To make this easy the cables are numbered.
y
Disconnect the cables connected to the controller.
y
Remove the defective controller from the system and in its place
install a new one.
y
Connect the cables to the controller again in the same manner as
they were on the old controller.
Before exchanging a RAID controller contact the DVS service
department.
The system your are working on operates with voltages
that can be hazardous to your health. Never work on the
system or access its interior with the power cable(s) being
plugged in. Make sure the power supply is disconnected
from the components you intend to work on.
Maintenance inside the system should only be performed
by personnel qualified for handling and testing electrical
equipment.
Computer hardware contains components that are sensitive
to electrostatic discharge. If you touch them without precau-
tionary measures, they can be destroyed. Use a wrist strap
connected to ground when accessing electronic parts and
take care of grounding the system. Avoid touching the inter-
nal components of the computer system.
To reach the RAID controllers you may have to remove an
air duct which is fastened to the system with several screws.
Only use original manufacturer spare parts. Other spare
parts might damage your system.
The controller must have the same firmware installed as the
other controllers.
