Performing a drive firmware update caused me a 38 hour day.
Some Seagate 10k and 15k u320 drives with firmware revision <006 have a problem, according to Seagate site . My drives are <3 months old, are maintained at 5 degrees above room temp, no media errors, random drives would be failed. Lsi u320-2 adapter
The Seagate Enterprise utility was used to upgrade the firmware.
To be safe I choose to update the firmware one drive at a time, via a standard scsi adapter attached to the backplane channel (with the raid adapter detached).
The first drive was the "hotspare" drive; the firmware updated successfully, all drives were OK according to my backplane diag LEDs. Upon restart, with the raid controller attached, two different drives failed. Spent about two hours trying to resuscitate the array, gave up, updated the firmware on the remaining drives, rebuilt the array from scratch. Have updated drive firmware many times before, never having this happen.
The Seagate utility will not work on raid cards.
Seagate Enterprise util will freeze your server with a raid card installed, server will need a hard shut down.
