Moving Shelves from one rack to another: can I just faill over the controller?

[SEANTRACY]

6240 running 8.1.3  and we need to 2 of 5 move shelves from one rack to another.   Can I fail over the controller then power down the controller and shelves, move them, power them back on and fail back?   I have two shleves I need to move.

Is there data (aggregates) on these disks?

[SEANTRACY]

These are production shelves with aggregates volumes. 

[rwelshman]

If you power down the shelves, any data volumes located on those shelves would not be available. So you would need an outage for those volumes, unless you can clear off the aggregates prior to the move. Are you running 7-mode or C-mode?

In this case there is no supported way to do it online. Hot shelf unplug is supported starting with 8.2.1 and even then only for shelves containing unused unowned disks.

If it's not to late ...

This type of move is offline / requires extra available space.

You can unassign disks from one shelf (if you can spare the space :). Make shure it's the last one in chain.

If that goes OK, you can switch off the shelf, and move it to another rack.

Add shelf (by the book, as if it was new shelf).

Assign owner to each disk.

If it's OK, you can repeat procedure for each shelf.

Brute force, but might do the job.
