I'd say just the usual common sense stuff, if you know the data to go on the volumes is already compressed or not suitable for compression then don't use compression on the array.
The 8200/8400s are a bit weedy for compression, light use would be OK though.
In regards to moving to a new version dedupe store, skip the step to thining the volumes to the old CPG, just run the second command and tune them to the new CPG and convert with -dedupe.
Move a few volumes then run compactcpg on the old CPG to get some space back, rinse and repeat.
thanks for that. Would that apply even if the volume is already de-duped?
so i can run
tunevv usr_cpg NEW_CPG –dedupe MY_VOLUME
on an existing dedupe volume as well as any existing tpvv created under 3.2.2?
thanks
