What is wrong with using CPFMTXA nnnn to format and allocate your VM volumes.
Most Modern DASD subsystems are doing the basic formatting of the DASD volumes
and all that is needed on VM is to format cylinder 0 and Allocate the volume as
all PERM. Then format each individual minidisk as needed. If you need CP OWNED
areas, Make sure you format all these areas using CPFMTXA.

Scott,
The ICKDSF example that you have supplied places a standard OS vtoc
on the volume. We do the same zOS initialization here. We then run a
CPVOL under vm to initialize the volume. With the exception of vm
sysres, spool, page, 1 shared volume and swap; all of our vm volumes are
used for linux. In the USER DIRECT I allocate all linux volumes/mini
disks at cylinder 1, so that I preserve the OS vtoc; otherwise linux
will overwrite the OS vtoc. I don't know if that is related to your
problem.

Thanks, Larry and Robert! Since those jobs look pretty much like the
job we are running here - I'm wondering if these volumes are initialized
by z/OS first before giving them to z/VM? Here, it seems we are having
to do some things from z/OS before we can label them on z/VM.. Here's
the JCL they use:
//STEP01 EXEC PGM=ICKDSF,REGION=8M,PARM=NOREPLYU
//SYSPRINT DD SYSOUT=*
//SYSIN DD DATA
INIT UNIT(650A) VERIFY(SK650A) VOLID(SK650A) VTOC(0000,01,01) NIX
Since I'm a z/OS idiot (that's a pre-newbie) and don't really speak VTOC
- I don't know exactly what the above is doing and why it's needed for
DF/DSS to backup the z/VM volumes.
Thanks again!

Scott,
We backup our zVM volumes from zOS using DF/dss. The
following are the control cards that we use :
DUMP INDDNAME(VOLUME) -
OUTDDNAME(TAPE) TOL(IOERROR) OPT(4) -
CPVOLUME TRACKS(0,0,13299,14) ADMIN

Subject: DF/DSS backup of z/VM volumes
At my current location, DF/DSS on z/OS is being used to backup
the z/VM volumes, including Linux guest volumes.. On some of the
volumes, the following occurs:
ADR307E (004)-OPENCL(11), Unable to open volume xxxxxxx, 16
This is indicating an invalid VTOC from what I can tell.. We
are using ICKDSF CPVOL to initialize/label the disks on z/VM.
Is there something special outside of ICKDSF that needs to be
done so that DF/DSS can backup the volume? I know this is the z/VM
mailing list - but hoping some of you may have similar requirements and
some ideas. I heard a rumor of some dataset being written to 4 tracks
of cylinder 0 .. but unconfirmed.
Thanks!
