It looks good. So my next question is why are you coding a VOLSER when you

For SMS Management I rarely code a VOLSER. Or if I do, the users use VOL(*)

I agree with the others. Check you ACS code for either USER filtlist or
VOLSER
I would also use ISMF TEST function and code the VOLSER and see what
happens.
I would think your TEST should have issues if you code the VOLSER in the

You're right. I had forgotten about the S/360 model 67. Most of the 360s in
