Can you use the “disk replace –m” command to swap out disks within in a raid group. I have a customer that wants to swap out 300GB disks and replace them with 450GB disks and once all of the raid group disks have been swapped get the max capacity of the new disks within the aggregate. Can you do this or as anyone done this before…
Thanks
Kevin

Unfortunately, this won't do what you want. The larger disks will be "rightsized" down to the size of the original smaller disks in the plex. You'll end up with something similar to wht is shown below:
filer> aggr status -r aggr1
Aggregate aggr1 (online, raid4, reconstruct) (block checksums)
Plex /aggr1/plex0 (online, normal, active)
RAID group /aggr1/plex0/rg0 (reconstruction 1% completed)
RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks)

Sorry I agree with Doug. Is it possible to 'lend' then a shelf and snapmirror {vol copy if no license} and then remove the old shelf?
Hope it helps

Thanks for your comments It’s what I thought. I will use the snap mirror option.
