Before you begin
Observe the following:
Removing a module from an operational
enclosure significantly changes air flow within
the enclosure. Openings must be populated
for the enclosure to cool properly. Leave
modules in the enclosure until a replacement
Parts can be damaged by electrostatic
discharge; use proper anti-static protection.
Keep parts in electrostatic containers until
needed and ensure you are properly
grounded when touching static-sensitive
When replacing both controllers
in an operational enclosure, do as follows:
Replace one controller as detailed in these
Wait 30 minutes. This pause ensures that the
controller and its ownership of the vdisks has
enough time to fully stabilize.
Check the system status and event logs to
ensure that the system is stable.
Replace the other controller as detailed in
When two controllers are installed
in an enclosure, they must be the same model.
Mixing controller types in the same enclosure is
To reduce the impact on system performance, perform
all maintenance tasks during periods of low system
activity or during a system maintenance window.

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,
software management utilities, and device LEDs, to
confirm that the module has failed.
Table 1 LED descriptions
Solid Green = Module is operating
Blink = System is starting up
Off = Module is not operating
Solid Amber = Fault condition
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.
To obtain key settings using the SMU, from the
Configuration View panel, select the system and then
click the following menu options:
For date, time, and NTP settings:
Configuration > System Settings > Date, Time

For mapping information, in the main panel,
select Maps. Scroll down to see details.
Enabling 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. HP recommends enabling this
To view or change the current Partner Firmware Update
setting, select the system in the Configuration View panel
