Drives Are in AVR mode.

All of a sudden i see that all the driver connected to the media server shows AVR,, i can see the drive physically in OS level, also in NBU. 

Robtest is also working , i can control the robot. i have bonunced the NBU service on media server. 

Media server is active for both tape and disk. i am suspecting if its library . before i request for library reboot , just wanted to know if i have to check for something else too.

Media server is an appliance.

You still have robtest running!

tldtest -rn 0 -r /dev/sg38

Kill it! Close it!

Well - robtest itself can cause drives to go in AVR mode.
Check and confirm that nobody has left an instance of robtest open.

Please show us output of these commands on the robot control host:

scan -changer

vmoprcmd

Check for errors in /var/log/messages. 

What are the robot console/web interface showning ?

Can you see the robot in the OS ?

Are the robot control daemon(s) running ? tld & ltdcd for tld robots

How is the robot shown in netbackup under devices ?, have had an occurence where it was enabled NO which meant the drives stood as AVR. In that case it turned out there was an issue with the robotics (gripper&arm) in the robot.

 

The standard questions: Have you checked: 1) What has changed. 2) The manual 3) If there are any tech notes or VOX posts regarding the issue

attached the results..

Also checked /var/log/messages. , i see below messages..

Double check drive config as well on this media server to ensure NBU is configured correctly with robot posistion for the drives:
tpconfig -l 

There should be more in messages file - not only errors related to one drive. 
A least during NBU restart there should be messages related to tldcd. 
Is tldcd running? And tldd for each robotic drive?
Can you manually stop ltid (using stopltid and check that all Media Manager processes are stopped) and restart with 'ltid -v' ?

Which Media Manager processes are started at this point?

Use 'vmps' command to list Media Manager processes.

PS: 
Device config seems to be in a bit of a mess with DOWN drives, Missing Path, etc.
And WAY too many tape drives attached to a single media server....

I went reading the messages , do see tldcd were shutdown abnormally during services restart..

Sep 29 18:40:09 xrxsenbumed02 tldcd[30991]: Daemon has terminated abnormally
Sep 29 18:48:55 xrxsenbumed02 ltid[30852]: Sending shutdown to tldcd daemon...

Sep 29 18:49:05 xrxsenbumed02 tldcd[3081]: Daemon has terminated abnormally

i have tried restart ltid manually too.. below are mm process active

root 30859 1 0 Sep29 ? 00:00:01 vmd -v

 

Theres too many backup active on this media server via disk. so  need to wait if i have to restart the NBU services again.

You really have way too many tape drives hanging off this media server/appliance.
