Excuse my ignorance, but what is FBAF?
This is a minidisk definition in the user directory:
MDISK FBAF 3390 4819 1000 VMBL2H WR
FBAF is the virtual address of the disk.
When we first ran into this, we were doing experiments and weren't sure if we
are able to reproduce the problem. But we had
Thanks for the replies, here are my thoughts on the problem:
I agree that before a minidisk is given to a guest (before the guest is started
for the first time) the minidisk needs to be formatted and any data that was
previously on the disk erased. The question is, when to do it and from which

Here is another possibility.
As in your possibility number 1 write a CMS format on every new disk.
Then run CMS2CDL exec which can be downloaded from IBM's VM download page.
The CMS2CDL runs very quickly, it only writes a CDL VTOC with LINUX
partition information.
CMS2CDL first checks that the
Hi Tomas,
I have a possible solution for you from within Linux. You can set the
device online with raw_track_access enabled.
$ echo 1 /sys/bus/ccw/devices/0.0./raw_track_access
$ chccwdev -e
Please ignore the few Buffer I/O errors in syslog.
Afterwards you can format the device
Thanks Stefan,
this is actually a path I was investigating today except that I took a slightly
different approach. I have noticed that the Linux driver looks at the size of
the first records on the track to check if it is any recognizable format. It
checks if the key is 4 bytes long. So I

You want openoffice. I believe the site is openoffice.org.

Good point on the MIPS. But based on my own experience sometimes you have to
prove to others that this is REAL Linux and not some bastardization contrived
for the mainframe.

I've just started looking at macros under in Calc (Open/Libre Office)
and there appears to be a significant difference in the way
complicated macros are handled. At this early stage of looking, there

Tomas,
There's another possibility: format the DASD from CMS using the LXFMT program.
That eliminates the need to format again from Linux. LXFMT is available on
Sine Nomine's web site.
