The file is transferred to the RAID controller where it is temporarily stored prior to
download to the enclosure. Once the firmware update process has started, a page
shows the update progress of each enclosure, including when the firmware update
has completed successfully.
This operation can take several minutes to complete. During the update, the
following operations are blocked so that they do not interfere with the update:
Updating controller software (buffer interference)
Saving logs to a file (buffer interference)
10. When processing is complete, verify that the proper firmware revision is reported
for each updated enclosure.
The Stop Device Firmware Update button stops the update operation at the next
point that will leave all expansion modules in a clean state. If you click this button
while the file is being downloaded to the controller, the download stops in a few
seconds and no expansion modules are updated. If you click this button after
download to the enclosures has started, the process is stopped after the update to the
current expansion module is complete. No updates that are already done or started
are undone. It can take several minutes for a stop operation to complete.
The Abort Device Firmware Update button immediately stops the
firmware update and leaves the expansion module in an unknown, possibly unusable
state. If you choose this option, wait two minutes to enable the expansion module to
possibly finish writing to its nonvolatile memory.
