Expanding the EVA

Our EVA3000 is full. All shelves have disks in them. In order to add space we need to replace our existing 143GB drives with 300GB drives. This is a rather expensive way to gain more space, as that extra 157GB of space costs the same as 300GB of space. But, that's what we have to do.

And wow does it take a while.

First I have to ungroup the disk. This can take up to two days. Then I pull the drive, and put the new one in. And regroup on top of it, which takes another up to two days. All the group/ungroup operations are competing for I/O with regular production.

Total time to add 157GB to the SAN? Looks to be 3 days and change.

We need a newer EVA.
