Implications of having different versions of disk firmware on the same EVA Disk Group
Does anyone know what are the implications of having different versions of disk firmware on the same EVA disk Group. If there is no impications how far apart can the versions be.
Also what are the recommendations of updating the disk firmware. We have a fully populated EVA8100 and every time a disk is replaced, the new disk may come with a newer firmware.
Thanks

Re: Implications of having different versions of disk firmware on the same EVA Disk Group
here is the disk firmware bundle which can be applied to see if you are ok with the EVA disk firmwares. It automaticaly selects the appropriate firmwares to the relevant disks:

Although you can always find a previously unreported bug, I've never seen an avisory saying that a newer version of disk firmware was incompatible with an older version of EVA firmware.

Re: Implications of having different versions of disk firmware on the same EVA Disk Group
you dont need the downtime for the this kind of EVA disk firmware upgrades - they are fully online, the process takes only one disk a the time, there is no risk of the double disk failure after the firmware upgrade, it is a background operation and therefore it takes longer time, but during the production IO...
