HP StorageWorks Replacing an HSG60 and HSG80 Cache Module Installation Instructions (EK-80CAH-IM. F01, March 2005)

 4. For the operational controller, note that in Mirrored
mode, FRUTIL initializes the mirrored portion of the
replacement cache module, checks for old data on the
cache module, and then restarts all device ports. After
device ports restart, FRUTIL tests the cache module
and the ECB. After the tests conclude, the device
ports are quiesced, and a mirror copy of the cache
module data is created on the newly installed cache
module.
H 5. Determine whether the controller associated with the
replacement cache module is installed, and then
complete one of the following options.
H ■ If the controller associated with the replacement
cache module is not installed, FRUTIL exits
automatically. After FRUTIL exits, refer to other
instructions for installing an HSG60 or HSG80
array controller in dual-redundant configurations.
■ If the controller associated with the replacement
cache module is installed, continue to the next
step.
H 6. For the controller associated with the replacement
cache module, note and observe the following:
H ■ The controller restarts.
H ■ The controller restart takes up to 60 seconds,
indicated by the temporary cycling of the port
LEDs and a flashing controller Reset button.
H If the controller does not restart, complete the
following substeps:
H a. Press and hold the controller Reset button on
the controller.
H b. Reseat the program card in the controller.
H c. Release the controller Reset button.
 7. For the operational controller, complete the following
substeps:
 a. Observe that FRUTIL restarts the device ports
and then exits.
 b. Identify invalid or failed cache conditions by
entering the following command:
SHOW THIS_CONTROLLER
 c. Clear invalid or failed cache conditions, if any
exist. Refer to Table 14 through Table 16 in the
“Controller and Cache Replacement
Troubleshooting” appendix of the HP
StorageWorks HSG60 and HSG80 Array
Controller and Array Controller Software
Maintenance and Service Guide for more
information on clearing invalid or failed cache
conditions.
Caution: Failure to clear an invalid cache message
(especially a Cache is FAILED message) before setting
the Failover mode can result in a recursive bugcheck error
message that renders the controller unusable.
 d. Disconnect the PC or terminal from the
maintenance port of the operational controller.
H 8. For the controller associated with the replacement
cache module, complete the following substeps:
H a. Connect a PC or terminal to the maintenance port
of the controller associated with the cache
module to be replaced.
H b. Identify any invalid or failed cache conditions, if
any exist, by entering the following command:
SHOW THIS_CONTROLLER
H c. Clear invalid or failed cache conditions, if any
exist. Refer to Table 14 through Table 16 of the
“Controller and Cache Replacement
Troubleshooting” appendix in the HP
StorageWorks HSG60 and HSG80 Array
Controller and Array Controller Software
Maintenance and Service Guide for more
information on clearing invalid or failed cache
conditions.
Caution: Failure to clear an invalid cache message
(especially a Cache is FAILED message) before setting
the Failover mode can result in a recursive bugcheck error
message that renders the controller unusable.
H d. Disconnect the PC or terminal from the
maintenance port of the controller associated
with the replacement cache module.
 9. For the operational controller, complete the following
substeps:
 a. Connect a PC or terminal to the maintenance
port.
Caution: In substep 9b below, 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.
 b. Re-establish the previous Failover mode by
entering one of the following commands:
SET FAILOVER COPY=THIS_CONTROLLER
or
SET MULTIBUS_FAILOVER
COPY=THIS_CONTROLLER
