Thank you for the update MammaGutt, much appreciated.
MammaGut, Does AO need to be stopped? AO is scheduled to run at night and tunevv we will be running at morning.
Also as i mentioned now major chunk of data is residing on default CPG FC10K and very less data are there on SSD and NL.
So running tunevv on only FC10K to the SSD CPG drive will be enough? My confusion here is that there is some data residing on SSD and NL as well which are moved to them as part of AO
No need to worry about AO.
No need to worry about where the blocks are today, you are moving everything with tunevv. You are not running tumevv on the FC10K CPG but the volume.
Just remember that if you move it to a SSD CPG which is a part of any AO config AO will start moving data down on first run, so remember to tune to a CPG which isn't a part of any AO config if you want the entire volume to permanently stay in the SSD tier.
