Better check to see if the DFDSS Standalone restore supports CPVOLUME before
going to far into the abyss!

Yes, since that is what will make the volume available to z/OS.
Actually, you can format any CP volume from z/OS. A user volume (one that
does NOT contain directory, T-disks, parm disks, paging, spooling, or
other CP-managed extents) can be formatted by ICKDSF CPVOLUME or INIT on
z/OS, as CP only looks at the volser on a standard VOL1 label.
For CP-owned disks, you should format it using ICKDSF CPVOLUME FORMAT.
I believe that CPVOLUME and INIT do not write the same style of VTOC. A
CPVOLUME will appear to have no available space. An INITed volume, OTOH,
appears empty except for the catalog. (I'm too lazy to test that theory.)
So while you CAN init with INIT, you SHOULD init with CPVOLUME.
