Hi guys,
Has anyone seen any issues with using the reallocate command in relation to a) increase in snap shot usage b) performance impact c) length of time to run the reallocation?
I may have a requirement to reduce the raid group size option( currently 28 ) on an existing 12 disk aggregate to 16 and add additional disks, thus potentially creating the presence of 'hot disks' in the primary raid group which will have been increased from 12 to 16 disks.

Any feedback on past experience would be useful.
I'm running ONTAP 7.0.4 on an FAS940 cluster with legacy LRC modules and 36G disks.
Thanks, Philip
