I hope you have a test system, or the Starter system from TAPE or even
an old release of CMS available.
Are you using DIRMAINT ? and do you have DISKMAP available?

Something seriously stepped on MAINT's 190 minidisk, as far as I can
tell. Try this:
LOGON MAINT
DEF 190 590
DEF 490 190
IPL 190
This makes the 490 disk, which is the clone of 190 that you do your
servicing of CMS on, the 190 disk (which becomes the 590 disk). If the
new 190, the 490 disk, IPLs clean, DDR it back to the 190 disk and then
relabel the 190 disk so you can get a clean 190 again.
BE SURE NOT TO CONFUSE THE GOOD DISK (was 490, is now 190) WITH THE
CORRUPTED DISK (was 190; now it 590).
(This process is detailed in your "z/VM Service Guide," under "Place
Components into Production," step 12, page 3-74 in the US English
version for z/VM 4.4. Skip the steps about 19E/49E, 5E5/5E6, and
193/493; go to the DDR steps and continue through "Rebuild the CMS Saved
System" on 3-75. It assumes that 190 is the regular 190; if you've
swapped 190 and 490 to be 590 and 190, you'll need to change the
procedure accordingly.)
Then figure out who or what stomped on your 190 disk. For starters, look
very hard for minidisk overlays.
Standard reminder: [EMAIL PROTECTED] is the better list for
VM-specific questions like this. (Even better: be at SHARE this week in
Boston....)
