Before you begin
HP controllers are warm-swappable under normal conditions. Thus, when
a failed controller is halted, the other remains in operation. The failed
controller can be replaced and the new controller brought online. The
user always has access to at least one controller and all user data.
Observe the following precautions when replacing a controller.
CAUTION:
HP recommends that you perform the replacement procedure
within seven minutes. Ensure all necessary parts are available
so the procedure can be completed without interruption.
Removing a controller module significantly changes the air flow
within the enclosure. Both controllers must be installed for the
enclosure to cool properly. If a controller fails, leave it in place
in the enclosure until a new module is available to install. The
enclosure could shut down due to overheating unless the
controller is replaced within the recommended seven minutes.
Parts can be damaged by electrostatic discharge. Use proper
anti-static protection. Refer to the documentation that shipped
with your system for additional information.
NOTE:
•
Alloy (gray)-colored latches on components like the controller
means the component is warm-swappable. Halt the I/O of the
failing controller with HP Command View EVA before removing
this component.
•
Under normal circumstances, while replacing a failing control-
ler, the other controller remains powered on and operational
and all data is accessible.
•
There are two controllers at the rear of the controller enclosure.
See
Figure 1
for the locations.
