[Info-vax] Proper dismounting of disks at shutdown

[JF Mezei]

OK, i am now at a stage where I boot my DS10L on demand and shut it down
when I am done. (to save on pwoer and heat generation).

I have found that my procedures have been grossly inadequate in the
past, but since I rarely shut down the VMS systems (and the Alpha didn't
have ALLIN1), I never noticed the problems.

The problem: upon reboot, mount verification of 1 drive takes 20 minutes.

I've looked at the shutdown process and I am finding the following still
opened at the time the dismount command is issued:

$ show dev /files $disk2

This is after an INSTALL PURGE to remove all installed images (except a
couple that are marked /NOPURGE so that the system can contineu its
shutdown)


Is there a way to force global sections to be closed ?

also, if I do an MC SYSGEN DEINSTALL/ALL , is there a way to ensure that
my shutdown process isn't mapped to a page file on that second drive
that is causing problems ?

How does the system manage to cleanly dismount the system drive but
can't do the same for my second drive ?

I've had an instance where NOT doing the rebuilding caused problems with
ALLIN1 ,and ANA/DISK/REPAIR generated a gazillion errors due to "open
file" flags erroneously set (but it doesn't repair those).


Yeah, I know, I can mount/noverify at boot time, but if I still end up
having to do it later, it will still take 20 minutes to get done.


Also, when doing a shutdown, at the end of SYSHUTDWN.COM (site
shutdown), what processes must still be left running for the shutdown to
be able to complete ?
