Hi

You can use CBRSPLCS which is a sample program in SAMPLIB.
If you use DFSMSrmm, EDGSPLCS can be used.

Best regards,

The tapes do not have any data on them.
They are marked as scratch in the TMS, Tape Catalog and VTL.

Subject: Re: Virtual volumes assigned wrong category on TS7770

Did you check all datasets on the tape?  I.E. Label=2 or higher.

Hi,
During an audit of our virtual tape system, we found many virtual volumes
that were assigned the wrong category.
This caused these virtual volumes to be unusable.
We're trying to correct the problem.
If we use ISMF option 2.3 (Mountable Tape) to change the attributes of the
virtual volume to PRIVATE and then back to SCRATCH, the volume is assigned
the correct category.
We're looking for a way to do this in batch, since we have a about 400
virtual volumes that need to be fixed.

We tried using these commands:
ALTER VD02026 VOLENT USEATTRIBUTE(PRIVATE) STORAGEGROUP(TAPE)
ALTER VD02026 VOLENT USEATTRIBUTE(SCRATCH)

But they don't do the job.
What are we doing wrong?

We're using z/OS v3.1.

Thanks

Gadi
