Bobby,
I went through a one-time process which created, in turn, defined minidisks of
various sizes (ex. 100 cyls, 400, 3338, 5008,10016, etc), attached them to
Linux-390 guests, formatted them as EXT3, and then unmounted and detached them.
I then used CMSDDR to dump them to an "empty EXT3" CMS disk. CMSDDR packs them,
so the 10016-cyl ends up taking just over 100 cylinders. Ex:
FILENAME FILETYPE FM FORMAT LRECL RECS BLOCKS
0060M 100 T1 V 3257 1502 189
0242M 400 T1 V 3546 6002 755
2160M 3338 T1 V 3734 50072 6325
3257M 5008 T1 V 3737 75122 9600
6547M 10016 T1 V 3737 150242 19222
A REXX exec links to the minidisk of the Linux guest that you want to "format",
selects the file with the filetype = size of the minidisk, and CMSDDR RESTOREs
it. ICKDSF then runs a CPVOL LABEL command to set a label of "0Xccuu" tomatch
the Linux machine's minidisk address. The Linux guest can then link to its new
disk and put it to use.
In your example, where you've got 60 to "format", fire up a half-dozen CMS
worker machines and give each 10 disks to format in parallel.
The concept is pretty simple. I can share the REXX programs with you if you
like.
