Removing Failed/Installing New Controller Module; Transporting Compactflash; Verifying Proper Operation/Configuration Settings; Updating Firmware - HP MSA 2040 Replacement Instructions

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
Page 2
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.
