[fa.info-vax] Dismount problems with RM05

From: Patrick O'Neill <poneill@AMSAA.ARPA>

	We have a VAX 782 running VMS 4.1, and I am experiencing a
problem in dismounting RM05 packs. What happens is that when I issue
the DISMOUNT command, the disk status on a show device becomes marked
for dismount, and then becomes timed out. If you reissue a dismount
command, DCL says that the device is not mounted. However, if you issue
another mount command, DCL says that the device is already mounted.
Can anyone shed any light on the situation ? It doesn't seem to happen
all the time, and I haven't determined if it's a specific pack that is
casuing the problem. Thanks in advance for any help.

RM05 dismount problem:

This *may* be software related.  You will get an effect similar to that
described if there are open files on the disk.  This includes installed
images which may not at that moment be in use.  Note the count at the end
of the line when you do SHOW DEVICE.  This should be the number of channels
open to the device.  Also do SHOW DEVICE/FILE  and this will show just what
files are open and by whom.  Files with no PID associated are generally
INSTALLED images or global sections.  I sometimes get this effect when
there is a global section open which I forgot about.  For regular open
files, kill the user (maybe tell him/her first); for installed images,
deinstall them; for global sections (created in a program)  you'll have to
write a program to delete them.

The timeout problem you mention does not ring a bell so maybe its some
other situation you have.
