I just did basically the same thing. I have a 940 that had some old shelves and just got a new shelf with 14x144GB drives. I needed to increase volume sizes so I created an aggregate on the new shelf, snapmirrored the data from the old shelves to this one, made a new root volume within the aggregate (copied etc into it and did the required edits) and once the snaps were done, booted into the new root. I left the old volumes online for a while after this to be safe but then destroyed the volumes that were on the old shelves. This would be the point I would take off the old shelves myself but I need to reuse mine.

Hello, I have a FAS940 (7.1.1.1) that has multiple shelves. I want to remove 4 of the older shelves to take them out of service. These 4 shelves contain /vol/vol0, which is the root vol.

My plan is: 1) move the root vol to another volume 2) reboot filer off of the new root volume. 3) Halt filer 4) Remove the 4 old shelves (all remaining shelves are DS14Mk2's) 5) boot filer

Do I need to do anything before I halt the filer (like vol offline, vol destroy) ?

What will the filer do when it boots up the second time and is now missing the 4 shelves ?

The /etc directory is really the only data that is in use on these old shelves now, so a destroy is ok, but the cautious side of me would rather save old /vol/vol0 on these shelves -- just in case.

I have searched for this answer, and even opened a support case, but I've only found "probably" type answers.

Thanks !

Paul
