Is it possible to downgrade XCS firmware?

Re: downgrade XCS firmware

Why would you do this?

You might have to do the following things to have a fully supported environment

1) Downgrade switch firmware
2) Download firmware HBA's
3) Download drivers for HBA

Verify the compatibility matrix before you do this.

Re: downgrade XCS firmware

Possible or not, why do you want to do this?
You should really have a version newer than 6.0!

Hope this helps!

Re: downgrade XCS firmware

A colleague was supposed to have installed CV:EVA 7.0.0 last week. Without checking i upgraded the firmware to XCS6.11.

I'll probably leave it if it doesnt affect the array which it hasnt but ive seen some support matrices recommend firmware 6.00 or 6.10 and was wondering if its possible.

HP always say never to downgrade controller firmware but i was wondering if anyone had done it or was possible.

live and learn

Re: downgrade XCS firmware

IMHO you should keep the installed version and do NOT downgrade.

See the release notes:

"To downgrade, it may be necessary to reinitialize the storage system and restore all data. Before proceeding with a downgrade, you must contact HP Services to determine if a downgrade is allowed in your configuration and, if so, to schedule the procedure."


Hope this helps!

Re: downgrade XCS firmware

CV-EVA V6.0.2 can manage XCS V6.1xx.

I agree that it is NOT NOT NOT a good idea to downgrade an EVA without consulting from HP, first. Almost every firmware upgrade seems to make little changes to the EVA's meta data. Therefore I would assume that any downgrade results in immediate data loss.
