This is what I do to find the device an nsrmmd process is using on a RedHat
Linux Server.
Run:
ps auxw | grep nsrmmd
root 19659 0.5 0.0 5324 2560 ? S< Jul17 21:36
/usr/sbin/nsrmmd -n 2
root 19662 0.0 0.0 4300 1508 ? S< Jul17 0:00
/usr/sbin/nsrmmd -n 3
root 19658 0.1 0.0 6436 3328 ? S< Jul17 6:04
/usr/sbin/nsrmmd -n 1
|
Grab the process ID and go into it's running directory in the /proc dir. So
for instance if I wanted to look at "/usr/sbin/nsrmmd -n 1" then I would cd
into:
cd /proc/19658/
Next go into the "fd" directory. If you do an:
cd fd/
ls -la
You should see something like this:
l-wx------ 1 root root 64 Jul 20 10:52 0 ->
/nsr/logs/daemon.log
l-wx------ 1 root root 64 Jul 20 10:52 1 ->
/nsr/logs/daemon.log
lrwx------ 1 root root 64 Jul 20 10:52 10 -> /dev/nst1
l-wx------ 1 root root 64 Jul 20 10:52 2 ->
/nsr/logs/daemon.log
lrwx------ 1 root root 64 Jul 20 10:52 3 -> /dev/null
lrwx------ 1 root root 64 Jul 20 10:52 4 -> /dev/null
lrwx------ 1 root root 64 Jul 20 10:52 5 ->
socket:[158000353]
lrwx------ 1 root root 64 Jul 20 10:52 6 ->
socket:[158000361]
lrwx------ 1 root root 64 Jul 20 10:52 7 ->
socket:[158004653]
lrwx------ 1 root root 64 Jul 20 10:52 8 ->
socket:[158004654]
lrwx------ 1 root root 64 Jul 20 10:52 9 ->
socket:[158006972]
As you can see this process is accessing my /dev/nst1 drive.
This information is ONLY useful on Linux servers and I am running RH AS 2.1
in my environments. If someone can respond back with any equivalents for
Sun that would be great.

Can you display the parameters used with the command (i.e. pslist ??
<PROCNAME>) that you can get the tape drive to display?
Thanks,
Brian

There is a program called "process explorer" that you can obtain from
www.sysinternals.com and if you have a look for the nsrmmd.exe process, it
will show you in the details what tape drive it's using. We use within our
win2k environment to kill 'stuck' devices from time to time.
Hope this helps!

Hi Chad,
Well that's exactly what I have. I was just wondering if there is an easier
way to figure out the hanging nsrmmd.
Your experience with Alphastor sounds not so good, any comment?

I used to see this issue all the time when we "used" to have AlphaSnor.
When it happened we just found the offending nsrmmd process and killed it.
To find the offending nsrmmed process.....well that is another story.
Best
bet is to do an strace on all of the nsrmmd processes (if you are running a
*nix) and kill any of the processes that are not doing anything. Nsrd will
notice that they died off and automagically start them back up again.

I wish I could read Hrvoje's response, but ...
1. I don't think you can use the -H option for a single drive.
2. Maybe Solaris behaves better than Windows, but it's been my experience
(since 6.1.3) that a hung nsrjb process will block any successive nsrjb
commands. Try to find the "nsrjb -l ..." process that was trying to mount
the volume and kill it.
3. In an AlphaStor environment, the "nsrjb -H" command doesn't actually
reset the jukebox, just tries to re-sync slot status with AlphaStor.
Use "nsrjb -HHv" to get NetWorker to realize that the drives have been
unloaded. Unfortunately, this will interrupt any other backups in progress.
4. Stopping and re-starting NetWorker services may have the same effect,
but you shouldn't have to delete and re-create the device.
