Shutdown a single shelf

[tbohuslovlm]

We have 2 controllers and 4 shelf's, 2 shelf's per controller.  Is is possible to just shutdown one shelf at time without causing any issues?  this is a our backup unit which is doing snap mirroring only.

If so, what is the proper way to shutdown a shelf?

thanks

Hi tbohuslovlm

The quick answer is: No, its not possible to shutdown one shelf of disk. Any particular reason?

Before the shelf was mounted and hooked up, the hard drives were tagged with number.  I need to pull the drives to see the number on them.

The last person did not do a very good job of inventory, hence I have to go and verify everything including each drive and that it matches up to inventory control has.

I was trying to figure out an easy way to do it.  I know the drives are hot swap but my understanding is that if I pull one out, thats working fine and put in back in it will have to index and redo the array?

Are you after the Disk Drive Serial Numbers? or did the previous person add a unique asset tag.number?

You could pull a disk, but then that would force the Filer to use a spare and rebuild the Aggregate/RAID Group.

You could also manually fail a disk, pull it, check and then manually unfail the same disk, but again each time you do this, the system will need to rebuild after each disk failure and you would need to zero the spares each time.

Thanks Martin, 

The person used a unique asset tag number on each drive.  Now they want to verify it.  I was not around when the filer and shelf were installed.

what would be the correct steps on shutting down the whole filer?  I am thinking that is probably the best option as failing each disk does not sound like a good thing to do.

Just use "halt -f" to shutdown filer. You better have console access to verify, when filer is down. Then when you finished with disks issue "autoboot" command to boot it again. You need to shutdown both controllers in active/active pair.
