Hey Lee,
We have been seeing this problem for a while now (running 7.3.x on
windows) although it has in the past been happening a lot more often
than every few months ... at the moment its probably once a week ... for
a while it was several RO devices a day ...
we have a case logged with EMC at moment and are waiting on a debug
binary for NSRD for our version of NetWorker ... we-ve been providing
them with various debug logs, but the problem has been a little hard to
pin down ...
in the mean time I have a script that runs every half hour that
re-mounts any RO devices that have unmounted ... it's a dos batch file
... but it would be fairly trivial to convert it to a Unix script ...
its listed below, and it probably overly complex, but it provides
reporting on status before and after re-mount attempts ...

Subject: [Networker] adv_file read-only device dismounting itself
Networker for Unix (Solaris) V7.4
For the 2nd time in six months, I've had a very strange occurrence: My
"read-only" (RO) adv_file disk device decides to dismount itself in the
middle of the night, causing serious havoc (read: logjam next morning)
on
the remaining backups, cloning, staging, etc.
The smoking gun can be seen on the system console:
[ID 702911 daemon.notice] NetWorker media: (waiting) waiting for
adv_file
disk DiskStorage.RO on BackupServ1
Here is what is seen in the Networker device display when it is failed:
Name Volume Name
/bigdisk DiskStorage
/bigdisk/_AF_readonly
Here is what is seen in the Networker device display after I manually
remount the RO disk device:
Name Volume Name
/bigdisk DiskStorage
/bigdisk/_AF_readonly DiskStorage.RO
Its status is properly set to ENABLED and READ ONLY in its properties.
------
Nobody is doing this manually, it is doing it all by itself. I've
scanned
the EMC support database and have yet to find any mention of this kind
of
behavior.
Before I report it to EMC support, I was wondering if anyone on this
list
had any hints or suggestions as to what might be happening?
Thanks!
