This post describes an scenario that was presented to me while upgrading disk drive firmware for NetApp E-series array.
Recently, as part of NetApp E-series firmware upgrade, the disk drive firmware upgrades were initiated. The disk firmware upgrades resulted in volume reconstruction (which completed successfully) and the disk firmware upgrade process stopped without any errors. While some drive firmware's were upgraded, there were some where the upgrade process was not initiated.
Upon investigation, it was identified that a UI timeout was causing the user to logout and gracefully stop the disk firmware upgrades. The fix was to disable the UI timeout for the duration of the upgrade and then trigger the disk firmware upgrade.
