HP SAN Firmware Updates

[Gongalong]

Hi folks,

 

Have any of you updated the controller and drive firmware on an HP SAN? Specifically, an MSA 2040 in our case.

 

Just checking how likely it is to be a smooth operation, or whether it can be problematic.

 

We of course have backups, but I’ll go belt and braces if there’s the remotest chance of it breaking the volumes etc.

 

(We’re updating due to a couple of controller crashes in the year we’ve been using it, update recommended by HP.)

 

Thanks

I updated two of these with no adverse affect however we did the controllers first one by one, the one with the latest firmware would take over, for the disks we had to stop all I/O on the arrays and disconnect the hosts which was a right pitta, then getting the hyper-v cluster happy again was the biggest problem.

HP's support recommended the separate controller update, although curiously their support document doesn't. It seems that the disk upgrade can be done as long as there's no data activity, which I'm hoping that VM shutdown will ensure.
