To reduce the impact on system performance, perform
all maintenance tasks during periods of low system
activity or during a system maintenance window.
The following illustration shows controller module
locations.
1. Controller module A
NOTE:
Illustrations in this document show generic
representations of modules and enclosures;
procedures are the same for all modules shipped
with this document.
Verifying module failure
Before replacing the module, look at the event log,
system management utilities, and device LEDs, to
confirm that the module has failed.
Table 1: LED descriptions
Module LED Description
FRU OK
•
Solid Green = Module is operating
normally
•
Blink = System is starting up
•
Off = Module is not operating
normally
Fault/Service
•
Solid Amber = Fault condition
Required
•
Blinking Amber = Hardware-
controlled power-up or cache flush/
restore error
•
Off = No fault conditions
Recording configuration settings
As a best practice, record system settings before
replacing a controller module.

Partner Firmware Update (dual-controller
configurations only)
In a dual-controller configuration, the Partner Firmware
Update option ensures that both controllers have the
most recent version. For controller replacement on an
MSA P2000 array, Hewlett Packard Enterprise
recommends disabling this feature to avoid
unintentionally changing the firmware on the controller
not being replaced. For all other MSA arrays Hewlett
Packard Enterprise recommends leaving this setting
enabled during controller replacement.
After both controllers are running the desired firmware
version, Hewlett Packard Enterprise recommends
enabling this feature for future firmware upgrades. For
the MSA2040/1040 and MSA2050/1050 arrays, it is
highly recommended to have this setting enabled at all
times.

Update setting.
