Re: DASD VOL1 doc
Not sure if I am jumping into the fire here, but the DASD VOL1 labels always used to be Classic (z)OS(MVS?) labels with an empty VTOC and no free space so if an OS system found one it wouldn't/couldn't use the space. Any way as such they were not documented in the VM manuals.

I have the GC33-5375-2 DOS/VS DASD Labels (Release 34) manual. Google only found 1 reference to it which is in the DOS/VS Program Directory for Release 34.

Re: DASD VOL1 doc
The best place for VOL1, HDR1 and HDR2 label info is the z/OS library. http://publibz.boulder.ibm.com/bookmgr_OS390/libraryserver/zosv1r9/ Richard R.

Re: DASD VOL1 doc
I used to have a 30 year old ?? OS manual that described the IBM format 1-5 DSCB fields. Don't know where I put it. Maybe it's with a S/360 Green Card or an old PofOPs manual. I found this when I did a search on IBM for VTOC. http://www.vm.ibm.com/pubs/cp31064/FMLRC.HTML it says: IBM Systems System z z/VM Programming Interface Information: This information is NOT intended to be used as Programming Interfaces of z/VM.
