We have an Dell EqualLogic 6500 SAN that is out of warranty. We pay a third party company for replacement drives. We currently have a few different drives installed with different firmware versions (dependant on the make/model/SN of the disk). These are Model: ST31000524NS Firmware: KD0A, Model: ST1000NM0011 Firmware: PD0A, Hitachi HUA723020ALA640 Firmware: MK70A8Q0 and Model: Hitachi HUA721010KLA330 Firmware: GKA0AB0A.
We recently had a disk die and had a replacement sent out, a ST31000NM0011 with firmware PD04. The SAN accepted the disk quite happily and the web portal display no errors. SAN HQ however reports a critical error that the disk firmware is out of date.
My questions are:
1. Other than SAN HQ complaining will the out of date firmware effect anything, the disk is currently a spare, if we have another failure can it still function as an active disk if required?
2. Our supplier has stated that they can get hold of a disk but it has a higher version of firmware than what we currently have. Can we use this disk instead, or as it is a higher firmware will it complain / will we have to upgrade the firmware on all the other disks?
3. As we don't have support with Dell, is it feasible to update the firmware on the disk myself, If so how can I obtain the firmware/ are there instructions to accomplish this?
Thanks for your help.
