About this document
• The Storage Management Utility (SMU) and the
Command Line Interface (CLI) can be used to
manage the enclosure. Tasks in this document
demonstrate using the SMU.
• For the latest product documentation, see the HP
Support Center website (http://www.hp.com/go/
hpsc).
• WARRANTY STATEMENT: To obtain a copy of the
warranty for this product, see the warranty
information website (http://www.hp.com/go/
storagewarranty).
Before you begin
Observe the following:
CAUTION:
• 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
is available.
• 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
components.
IMPORTANT: When replacing both controllers
in an operational enclosure, do as follows:
1. Replace one controller as detailed in these
instructions.
2. Wait 30 minutes. This pause ensures that the
controller and its ownership of the vdisks has
enough time to fully stabilize.
3. Check the system status and event logs to
ensure that the system is stable.
4. Replace the other controller as detailed in
these instructions.
IMPORTANT: When two controllers are installed
in an enclosure, they must be the same model.
Mixing controller types in the same enclosure is
not supported.
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.

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,
software management utilities, and device LEDs, to
confirm that the module has failed.
Table 1 LED descriptions
DescriptionModule LED
FRU OK
• Solid Green = Module is operating
normally
• Blink = System is starting up
• Off = Module is not operating
normally
Fault/Service Required
• 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 system information (name, contact, location,
and description):
Configuration > System Settings > System
Information
• For user information:
Configuration > Users > Modify User
• For email notification settings:
Configuration > Services > Email Notification
• For SNMP notification settings:
Configuration > Services > SNMP Notification
• For syslog notification settings:
Configuration > Services > Syslog Notification
• For information about scheduled tasks:
View > Overview
In the main panel, select Schedules. Scroll down to
see details.
• For information about all hosts (IDs and names):
From the Configuration View panel, select Hosts.
• For information about a specific host (IDs, names,
and mappings):
From the Configuration View panel, expand the
display under Hosts and then select a specific host.
◦ For overview information (including host IDs and
nicknames) in the main panel, select Host. Scroll
down to see details.
◦ 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
feature.
To view or change the current Partner Firmware Update
setting, select the system in the Configuration View panel
and then select Configuration > Advanced Settings >
Firmware. If needed, check the box and click Apply.

Removing the failed controller module
IMPORTANT:
• In a single-controller configuration, if
transporting the CompactFlash to a new
controller, remove the controller only after
the cache is copied to CompactFlash. The
Cache Status LED is off when the cache is
copied to CompactFlash.
• In a single-controller environment, I/O must
be stopped and the enclosure must be
powered off prior to the replacement.
• In a dual-controller environment, if the failed
controller is first shut down, the controller may
be hot-replaced in an operational enclosure.
1. In a dual-controller configuration, shut down the
failed controller:
a. Select the system in the Configuration View
panel and then select Tools > Shut Down or
Restart Controller.
b. Set the following options and then click OK:
• Operation—Shut down
• Controller Type—Storage
• Controller—A or B
The blue OK to Remove LED on the controller
illuminates, indicating that the controller can
be safely removed.
2. Locate the enclosure in which the controller module
OK to Remove LED is blue.
3. If you are replacing a controller in a single-controller
environment, stop all I/O and remove power from
the enclosure.
4. Disconnect cables connected to the module. Label
each cable to facilitate reconnection.
5. Turn the thumbscrews until the screws disengage
from the module (1) and rotate both latches
downward to disengage the module from the
internal connector (2).
6. Pull the module straight out of the enclosure (3).
NOTE: The illustration is for reference only.
In a single-controller system, remove the
controller module from module A, top
location.
Transporting CompactFlash (single-controller
configurations only)
CAUTION: In single-controller configurations, to
prevent data loss, the CompactFlash must be
moved from the failed controller to the new
controller. In dual-controller configurations, do not
transport the CompactFlash, as data corruption
might occur.
1. Make sure that transporting the cache is the
appropriate action to take as specified in the user
guide for your MSA model.
2. Carefully remove the CompactFlash from the
controller, label it Data, and set it aside.
3. Carefully remove the CompactFlash from the new
controller and set it aside.
4. Insert into the new controller the CompactFlash that
you removed from the failed controller and labeled
Data.
Installing the new controller module
1. With the latches in the open position, slide the
module into the enclosure as far as it will go (1).
Press firmly on the top-center of the module to
facilitate insertion, ensuring that the module is well
seated and flush with the chassis.
2. Rotate the latches upward to engage the module
with the internal connector (2) and turn the
thumbscrews finger-tight (3).
NOTE: The illustration is for reference only.
In a single-controller system, insert the
controller module into module A, top location.
3. Reconnect the cables.
After installing a controller in an operational,
dual-controller system, the new controller
automatically begins initializing. If the firmware
versions differ between the two controllers, the
Partner Firmware Update feature brings the older
firmware to the later firmware level.
4. In operational systems, if additional hardware
components, such as a second controller, need
replacing or installing, wait 30 minutes before
proceeding with those procedures. This time frame
ensures that the controller(s) and their ownership of
vdisks are fully stabilized.
Verifying proper operation
Examine the module status as indicated in Table 1.
If the replacement controller does not boot up as
expected or if the Fault/Service Required LED is amber,
the module is not online. Check the event log for errors,
and then restart the controller to put the module online.
To restart a controller, do the following:
1. Select the system in the Configuration View panel,
and select Tools > Shut Down or Restart Controller.
2. Set the following options and then click OK:
• Operation—Restart
• Controller Type—Storage
• Controller—A or B
Verifying configuration settings
After replacing a controller, verify that your system
configuration settings are set properly. Repeat the
commands shown in “Recording configuration settings”
and compare the current values with those recorded
before the installation. If necessary, change the settings
to their previous values. For more information, see the
HP MSA SMU Reference Guide.
Updating firmware
After installing a new controller, verify that the latest
firmware is installed on all controllers in the enclosure.
Go to the HP Support Center website and navigate to
the page for your enclosure. If newer firmware is
available, download the firmware to your local system
and install that latest version on the controllers. For more
information on firmware updates, see the HP MSA SMU
Reference Guide.
Returning failed items
In materials shipped with the replacement, HP specifies
whether the failed component must be returned. Follow
the provided instructions.
