HP StorageWorks Replacing a Gigabit Link Module (GLM) in an HSG60 and HSG80 Array Controller Installation Instructions (EK-80GLM-IM. D01, March 2005)

Note: After the GLM is fully seated, the controller starts automatically, and the Reset LED turns on. A controller restart can take as long as 60 seconds, indicated by the temporary cycling of the port LEDs and a flashing Reset button. Note: If the controller did not restart, use the following steps: a. Press and hold the controller Reset button.
b. Reseat the controller program card. c. Release the Reset button.
7. Connect a PC or terminal to the controller maintenance port. 8. From the CLI prompt, display details about the configured
controller using the following command:
SHOW THIS_CONTROLLER FULL
9. Set the date and time using the following command:
SET THIS_CONTROLLER TIME=dd-mm-yyyy:hh:mm:ss
10. Connect all host bus cables to the controller. 11. Mount the logical units on the host. 12. For Windows 2000 or Windows NT platform users, restart
the server.
13. Disconnect the PC or terminal from the controller
maintenance port.
Replacing a GLM in dual-redundant controller configurations Use the steps in “Removing a GLM” and “Installing a GLM” to
replace a GLM in dual-redundant configurations.
Tip: Refer to Figure 1 on page 1 while completing removal and installation procedures and identifying specific controller components.
.
Caution: Static electricity can easily damage a controller or GLM. Wear a snug-fitting, grounded ESD wrist strap.
Removing a GLM Use the following steps to remove a GLM in dual-redundant controller configurations: 1. Connect a PC or terminal to the maintenance port of the
operational controller. The controller connected to the PC or terminal becomes “this controller.” The controller being removed becomes the “other controller.”
2. Disable failover
and take the controllers out of the
dual-redundant configuration with one of the commands below:
SET NOFAILOVER or
SET NOMULTIBUS_FAILOVER
3. Start the Field Replacement Utility (FRUTIL) with the
following command:
RUN FRUTIL
4. Enter N(o) to the question about replacing the cache battery. 5. Enter 1 for the remove a controller or cache module option.
6. Enter 2 for the remove “other controller” option. 7. Enter Y(es) to confirm intent to remove the “other
controller.”
8. Wait for FRUTIL to quiesce the device ports—indicated by
an “All device ports quiesced” message.
Caution: Failure to allow the ports to quiesce can result in data loss. Quiescing can take several minutes.
Note: A countdown timer allows a total of 2 minutes to remove the controller. After 2 minutes, “this controller” exits
FRUTIL
and resumes
operations. If this happens, return to step 3 and proceed.
9. Remove the “other controller” in the subsystem:
a. Disconnect controller host bus cables or terminators.
Caution: For fiber optic cables without extender clips, use thin needle nose pliers to remove the controller cable to avoid damaging the cable (see Figure 3 on page 1).
b. Disengage both retaining levers, and then remove the
controller containing the failed GLM from the enclosure.
c. Place the controller on an antistatic bag or a grounded
antistatic mat.
10. Enter N(o) to the question about a replacement controller.
FRUTIL exits.
11. Unscrew the screw that secures the controller access door. 12. Remove the access door and set the door aside. 13. Disengage the GLM locking tabs that protrude through the
guide holes on the bottom side of the controller.
14. Operate the release lever on the exposed end of the GLM by
pressing the lower end of the release lever with your index finger while pulling the raised end up with your thumb.
15. Remove the GLM.
Installing a GLM Use the following steps to install a GLM in dual-redundant controller configurations: Note: Before inserting the new GLM, locate the holes on the controller board where the GLM is to reside. 1. Insert the new GLM by placing the cable connection end of
the GLM through the opening on the front of the controller from the top.
2. Align the locking tab on the bottom of the replacement GLM
with the board guide holes, and press firmly to seat the GLM.
3. Press the release lever firmly into place to secure the GLM. 4. Install the access door on top of the controller and secure the
door with the screw.
5. Connect a PC or terminal to the maintenance port of the
operational controller.
Note: The controller connected to the PC or terminal becomes “this controller”; the controller being installed becomes the “other controller.” 6. Ensure that the controller configuration is customized to your
needs, and then record the controller configurations (for example, Failover mode, cache status, serial numbers, SCSI mode, mirrored or nonmirrored information, and so forth).
7. Start FRUTIL with the following command:
RUN FRUTIL
8. Enter N(o) to the question about replacing the cache battery. 9. Enter 2 for the install a controller or cache module option. 10. Enter 4 to exit FRUTIL. 11. Enter Y(es) to confirm intent to install the “other controller.”
FRUTIL quiesces the device ports and displays a message indicating that the controller is being installed.
12. Wait for FRUTIL to quiesce the device ports—indicated by
an “All device ports quiesced” message.
Caution: Failure to allow the ports to quiesce can result in data loss. Quiescing can take several minutes.
13. Carefully align the controller in the appropriate guide rails.
Caution: Misalignment can damage the backplane.
Note: A countdown timer allows a total of 2 minutes to install the controller. After 2 minutes, “this controller” exits
FRUTIL
and resumes
operations. If this happens, return to step 7 and proceed. 14. Insert the controller, and then engage the retaining levers. Note: In step a, ensure that the program card is
not
installed in the
replacement controller.
a. Insert the controller (without the program card installed)
into the appropriate bay, and then engage the retaining levers.
b. Press and hold the controller Reset button, insert the
program card, and continue holding the Reset button.
c. Press and hold controller Port #5 button (see Figure 4),
release the Reset button and continue holding the Port #5 button for an additional 5 to 20 seconds.
Figure 4: Controller Reset button and Port #5 button on the OCP
The nonvolatile memory in the replacement controller is updated and halts with an LED code of 33.
d. Press and release the Reset button on the controller.
The controller restarts normally.
e. Wait at least 15 seconds after releasing the Reset button,
and then immediately complete step 15 below. Be sure to wait 15 seconds before continuing to step 15.
Note: A controller restart can take as long as 60 seconds, indicated by the temporary cycling of the port LEDs and a flashing Reset button. 15. Press Enter or Return within 3 minutes of completing
substep 14e above to exit FRUTIL, and then wait 1 minute to
allow the controller to restart.
Note: If you do not press Enter or Return within 3 minutes in step 15,
the operational controller issues an automated command to cancel the installation of the replaced controller. This cancellation causes all the port LEDs on the controller to go off. If this situation occurs, press Enter
to exit
FRUTIL
, and then, from the operational controller, enter:
RESTART OTHER_CONTROLLER
16. Configure the controller as described in the appropriate array
controller user guide or CLI reference guide.
Caution: In step 17, entering the appropriate SET command is critical. Enabling an incorrect failover mode can cause loss of data and incur system down time. Verify the original failover configuration and use the appropriate SET command to restore this configuration.
17. Enable failover and re-establish the dual-redundant
configuration with one of the following commands:
SET FAILOVER COPY=THIS_CONTROLLER or
SET MULTIBUS_FAILOVER COPY=THIS_CONTROLLER
This command copies the subsystem configuration from “this controller” to the “other controller.”
18. If desired, verify the failover configuration:
SHOW THIS_CONTROLLER FULL
19. To verify that the new GLM is functional, enter:
SHOW OTHER_CONTROLLER
20. Reconnect the host bus cables to the “other controller.” 21. Disconnect the PC or terminal from the controller
maintenance port.
