Is the path to th elibrary definately correct ?

On the robot control host, find the path to the library from tpconfig -d  (near the bottom)

Then run

echo 'mode' |tldtest -r /path/to/library  (this might work)

and

/usr/openv/volmgr/bin/scsi_command -f <path/to/library>

It looks like the robot is failing to respond to the scsi commands that are sent that would cause it to run an inventory, this is completly seperate from the 'library console inventory' and that fact that works is of course good, but has no significance on if the inventory related to NBU works.

All that happenes in a NBU inventory, is a scsi command(s) is sent to the library, and the library responds to NBU and tells  NBU where the tapes are - hence why this is very very very unlikely to be a NetBackup issue.

I'd suggest as a starting point (apart from the command above and sdos comments, rebooting the library via a proper power off/ on, and then trying again, and the media server that is the robot control host.

If (path is correct) and above still fails after the reboots, you'll probably need to be calling the hardware vendor.

Ok - looks like one master/media server.

What do these query commands show:

scan

tpautoconf -report_disc

.

BTW - do NOT run any of the other variants of "tpautoconf" - just yet.  Only run the above query commands please.

Okay here is sdo command output

To try mhp999 suggestion, I am getting  permission denied for tldtest command, So i need  other team support once done I will post the results

 

 

SO the paths to the drives and robot are missing.

This is at OS level

Try rebooting the server

I thought you said robtest is working fine?

robtest is calling tldtest.

There is no way robtest/tldtest can be working fine  if 'scan' cannot see the robot and 'tpautoconf -report_disc' is reporting missing devices.

Please show output of 'cat /proc/scsi/scsi' as well.

Scan shows nothing, meaning that the OS cannot see any medium changer or tape drives.  This is not a NetBackup config error.  This means the OS cannot see the devices, and therefore NetBackup cannot do anything at all.

The tpautoconf -report_disc means... "Hey Netbackup, show me the discrepencies/differences between what the OS reports, and what my NetBackup idea of my configuration says?".   In a normal working condition scenario this command would report nothing, i.e.no discrepencies.  But, because it does report discrepencies, then this means that NetBackup can no longer find the devices listed.

So, scan is empty.

And NetBackup reports it cannot find the devices.

You need to figure out from an OS level what is wrong.

What changed recently?

Hi All,

 

I tried to list the scsi please check the output.

I can do the robtest, here is the output  I dont know how.

So - earlier on the devices were 'missing'.
What did you do to get them back?

Reboot? 

Have you tried to Inventory again?
