How to downgrade firmware for FATA 1TB Disk drive

Dear all,

We have a issue that I'm not sure and I need for ur suggestion.

We have a EVA4400 storage system with a FATA Diskgroup. All disk in which have firmware is HP06. Unfortunately, a disk in this group came failure and we need to replace.
We replaced a failed disk drive by a new. But, the firmware's replaced new disk drive is HP07(I have looked up in HP document and sure that EVA4400 support HP07 firmware.
If we can mix disk drive into a diskgroup with different firmware?
Can I downgrade this firmware of disk drive in HP06

We really need ur help and suggest to issue this problem.

Thank u for ur suggest and attentions.
Thx so much

The right way is to upgrade all disks to HP07 firmware.

"If we can mix disk drive into a diskgroup with different firmware?"

Yes.


"Can I downgrade this firmware of disk drive
in HP06"

The ideal situation would be for you to do as suggested above. I would not specifically downgrade a disk firmware but rather upgrade the other disks if you are that worried.

Downgrade is possible, but better upgrade all to the current version.
Even a mixed situation is IMHO better than a downgrade.

Hope this helps!

Re: How to downgrade firmware for FATA 1TB Disk drive

Our customer want to downgrade, because they think that only a disk with different firmware.
They're afraid of online upgrade
I read some hp document about upgrading, if we can have some way to offline upgrade disk firmware?
Thx for ur response

Consider an online upgrade while the array is not fully busy.

Hope this helps!
