Marcy,
Terry has the best answer. Just get cyl zero formatted from z/VM and
allocate the entire volume as PERM.
In reality, I still have bad habits and format the whole volume.
Regards, Doug

Hi Marcy,
I use to format the whole volume under CPFMTXA or ICKDSF on z/OS and
then turn around only to have Linux format them again a real waste of
time.
So now I just init cylinder zero with a z/VM Label for doc purposes and
it works fine.
Thank You,

When we *had* zLinux POC guests, we formatted them under CMS using the
LXFMT utility, see:
http://www.sinenomine.net/products/vm/lxfmt
Once formatted with LXFMT, the disk was accessible from Linux without
dasdfmt. But your particular filesystem needs may require something
more
extravagant.

Re: ICKDSF format of new DASD
Hi Marcy
Based on our experience, we have no problem formatting just the first
five
cyl (0-5) before we attached them as linux dasd device mdisks. In turn,
they will format them using their own linux utilities.

What is the current recommendation for new DASD purchases and ICKDSF
CPVOL
FORMAT for disk to be used for Linux.
We've been formatting the whole thing. Once upon a time there was a
DASD
driver bug that this helped avoid, but I'm sure that has been fixed
before.
