Post subject:  Migration rest of LDs to CPG
I tried to migrate (Tune Virtual Volume) VV from one CPG to another. But eventually my empty CPG remained 1% capacity. Weird. I tried to look whats problem.

Code:
V400_zz cli% showcpg -r FC_cpg*

Ok
Code:
V400_zz cli% showvv -cpg FC_cpg_old
no vv listed

Strange ...
Code:
V400_zz cli% removecpg FC_cpg_old
Removing CPG FC_cpg_old
select q=quit y=yes n=no: y
Error: Some LDs in CPG FC_cpg_old are in use. This may be the result of an interrupted or ongoing tune process. The CPG cannot be deleted in this state.

Yes. Indeed it was when I canceled task on the some VV. But I forget with which VV i did it exactly.
Code:
V400_zz cli% showld -cpg FC_cpg_old
LDs for SA:
no lds listed
LDs for SD:

Also check/list your VVs "copy space". VVs can have their user Space in one CPG, but their copy space in another. Older versions of Inserv defaulted to assigning VVs a copy space, newer versions leave it blank by default.
