There is no special tunevv parameter per se, its just the standard, everyday tunevv... can you explain/link what this bug is you are talking about? I am doing something similar, an AO re-design, and need to pull all my SSD back down to FC.
The old method with system reporter based AO would be to set the tier0 capacity limit to 0 and let it drain out... however I don't see this functionally documented in the array based AO commands.
So manually:
Code:
ESFWT800-2 cli% showvvcpg HOSTX_L21_DB
----(MB)----- -New (MB)--
Name CPG Adm Snp Usr Adm Snp Usr
HOSTX_L21_DB PRD_TIER1_CPG_01 128 0 896 0 0 0
HOSTX_L21_DB PRD_TIER2_CPG_00 128 0 90240 0 0 0
-----------------------------------------------------------------------
1 - 256 0 91136 0 0 0
ESFWT800-2 cli% tunevv usr_cpg PRD_TIER2_CPG_00 HOSTX_L21_DB
Are you sure you want to tune VV 'HOSTX_L21_DB' ?
select y=yes n=no: y
