HSG80 Array Controller V8.7 Maintenance and Service Guide
4–23
Replacement Procedures for Model 2200 Enclosure Elements
CAUTION: Wait for FRUTIL to quiesce the device ports—indicated by an “All device
ports quiesced” message. Failure to allow the ports to quiesce might result in data
loss. Quiescing might take several minutes.
Carefully align the cache module in the appropriate guide rails. Misalignment might
damage the backplane.
IMPORTANT: A countdown timer allows a total of 2 minutes to install the cache module.
After 2 minutes, “this controller” will exit FRUTIL and resume operations. If this happens,
return to step 7 and proceed.
12. Insert the replacement cache module into the appropriate bay and engage the
retaining levers.
NOTE: The “other controller” restarts and then FRUTIL exits.
NOTE: A controller restart can take as long as 60 seconds, indicated by the temporary
cycling of the port LEDs and a F
LASHING
reset button.
IMPORTANT: If the “other controller” did not restart, use the following steps:
a.
Press and hold the “other controller” reset button.
b.
Reseat the “other controller” program card.
c.
Release the reset button.
NOTE: In mirrored mode, FRUTIL initializes the mirrored portion of the replacement cache
module, checks for old data on the cache module, then restarts all device ports. After the
device ports restart, FRUTIL tests the cache module and the ECB. After the test completes,
the device ports are quiesced and a mirror copy of the cache module data is created on the
newly installed cache module.
13. Enable failover and re-establish the dual-redundant controller 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.”
14. If desired, verify the failover configuration with the following command:
SHOW THIS_CONTROLLER FULL
15. Disconnect the PC or terminal from the controller maintenance port.
