Replacing the c
ontroller, controller cache, or controller battery
The following s
ections detail procedures for replacing an MSA array controller, controller cache module,
or controller cache battery pack:
• Before you begin
•Verifyingcom
ponent failure
• Removing the controller
• Removing the controller cache module
•Removingthe
controller cache battery pack
• Installing the controller cache battery pack
• Installing the controller cache module
•Installingt
he controller
• Verifying the replacement
Perform only the steps required for your service event. For example, re-seating an array controller includes
Removing the controller and Installing the controller.
Before you begin
CAUTION:
• Before removing a component or blank from an operational device, make sure that you have the
replacement part or blank available. Removing a component or blank impacts the airflow pattern
and cooling ability of the device. Allow approximately 30 seconds before installing the new or
replacement component to ensure that configuration data about the removed component is cleared
from the system registry, but, to avoid possible overheating, insert the new or replacement component
within one or two minutes. If the internal temperature exceeds acceptable limits, the device may
overheat and automatically shut down or restart.
• Parts can be damaged by electrostatic discharge. Use proper anti-static protection.
CAUTION:
• When replacing a controller, HP recommends that the old cache module be moved to the new
controller. In single-controller configurations, if the controller fails, this ensures that disk writes that
might have been trapped in the old controller's cache are completed.
• In dual-controller configurations, if a controller fails during an expand process, the old cache module
must
be migrated to the replacement controller to complete the expand process. If this is not done,
the array contents are invalid.
• In dual-controller configurations, hot-add or hot-replace a controller or companion I/O module only
during periods of low I/O. Hot adding or hot replacing these modules while under heavy I/O may
cause a momentary pause, performance decrease, or loss of access to the MSA while the new
controller is starting up. After the startup process is complete, full functionality will be restored.
• In dual-controller configurations, the MSA controller and companion I/O modules are hot pluggable
and the MSA does not need to be powered down during the replacement. However, you must first use
an MSA management utility, such as the SMU or MSA-CLI, to disable the controller before removal.
