The CMS format is only needed because some z/Linux routines get so upset
if the minidisk is not formatted they generate so many messages so
quickly that when the console is spooled they flood the VM CONSOLE
buffers causing an SXA004 CP abend.

OK, time to show my Linux ignorance...
I've never understood why Linux needs CMS to format the MDISK
before Linux formats it. What a waste of I/O's (even if z _does_
perform I/O VERY, VERY quickly!). What a waste of time, and what a set
of cludgy processes.
What's the deal? Why can't dasdfmt just format what it's given
without CMS having to "prep" it? What would it take to change dasdfmt
to do so?

Re: Formatter forz/Linux Minidisk from CMS
Kludge yes, one pack; no. Because of striping we would need at
least thirteen differently sized template minidisks. Unless we could
format just one very large minidisk and image copy as little as needed.
I believe CMS gets just a little bent out of shape if one did this.
Would not z/Linux too?

Kludgy workaround ...
Can you "correctly" format one "template" pack ... then use
HiDRO DUPLICATE (or DDR) to clone the pack with the end result being
that the packs are pre-formatted for the z/Linux guests?

Subject: Formatter forz/Linux Minidisk from CMS
Does anyone have or know of a utility that will z/Linux format a
minidisk from CMS?
We have a requirement to format many minidisks for z/Linux
usage. Many z/Linux routines flood the console if we just give the
guests unformatted minidisks. We have been CMS formatting them before
sending them to the z/Linux guests, where it might be days before the
owners z/Linux format them. I would like to be able to z/Linux format
the minidisks from CMS before giving the disks to the guests.
