I have been having problems with disks on my Dell PERC5/i Raid controller, and was instructed to update the controller's Bios (by Dell and by OpenManage).
One of these problems is disks getting a 'failed' status, but when physically removed and reinserted come online fine and just have be imported back into their array as a foreign config.
This has occurred again, this time with a RAID0 array (OUCH!!).
I would like to apply the firmware upgrade ASAP, and need to know if I should go to the datacenter first and futz with the disk, in case the firmware upgrade might in some way interfere with my abilty to do so afterward.
EDIT: What I am really asking is: could the firmware upgrade remove my ability to massage a "failed" drive back into it's raid array, if the failure is transient?
