Re: EVA disk addiing

Just insert the disk on an empty bay. Wait until it appears on Command View (under ungroupped disks). Then add it to an existing disk group.

No disruption to the hosts in any of the steps.

It takes what it takes - no need to worry, it is in the background with low priority.

Hope this helps!

Re: EVA disk addiing

Hi,

Yes you can mix disk sizes within a disk group, however depending on what the sparing level is set to, this could reduce the amount of available space, rather than increase it.

With single sparing, 2 times the size of largest disk in the group is reserved. With double sparing, 4 times the size of the largest disk is reserved.

More details about the number of disks in the existing group, and its current occupancy would help...

Hope this helps,

Regards,

Rob

Re: EVA disk addiing

You can reduce the Spare setting to give you some space back, add more disk or delete data. Also, yes you can mix and match EVA disk sizes and speeds in a disk group, but it is not recommended. The Best Practice paper lays out the various issues that could arise.
