Procedures for Array Controller Software V8.7x-x Release Notes
FRUTIL quiesces all device ports, indicates a time limit of 2 minutes to
install the replacement cache module, and begins displaying the time
remaining in 10-second intervals.
Caution: Wait for FRUTIL to quiesce the device ports—indicated by an “All
device ports quiesced” message. Failure to allow the ports to quiesce
can result in data loss. Quiescing might take several minutes.
Note: A countdown timer allows you a total of 2 minutes to install the cache module.
After 2 minutes, “this controller” exits
FRUTIL and resumes operations. If this happens,
return to substep 2b, and proceed.
H 3. For the replacement cache module, complete the following substeps:
H a. Carefully align and partially insert the cache module in the appropriate
guide rails.
Caution: Misalignment of the cache module in the guide rails can damage
the backplane.
Caution: If your cache module is in a BA370 enclosure, you must disable the
ECB. Failure to disable the ECB can result in cache module damage. To
disable the ECB, complete the following steps:
1. Disable the ECB by pressing the battery disable switch on the battery
module.
2. Connect the ECB Y-cable to the cache module.
H b. Insert the replacement cache module completely into the appropriate bay,
and engage the cache module retaining levers.
