    Hi Kasra

    Based on the output attached, you have lost connectivity to the EML robot (TLD 0) - the output is only showing the MSL6000 library. This corresponds to the NetBackup message indicating a "missing path" to the robot.
    All tapes drives appear to be available, so that's something. 

    As sdo  says you need to address that issue before attempting to get NetBackup to work.  

    Good luckj

    Hi

    I could finally solve the issue, after changing the OS and so many other steps, I found that the problem was from one of the HBA's ports .so I turned back to the last good known state of OS and changed the HBA.

    Everything is now working fine.

    Thanks by the way

Before we try to fix, let's make sure that all devices really are properly visible, because there's no point trying to re-add a device in NetBackup if the operating system itself cannot see a device.

Can you attach text files of the output of these commands from master server, and from each media server:

scan -changer
scan -tape

...and somehow show / indicate which server is which.

AFAICT, we're expecting to see two robotic changers (one physical (EML), one virtual (VLS)), and tape drives (phys+virt) for both.

If the devices don't show up, then I would do this:

1) reboot EML

2) reboot VLS

3) reboot medias

4) reboot master

5) re-check scan -changer and scan -tape

6) if devices are still not seen via scan commands, then check SAN elements...

6a) SAN switches ok?

6b) SAN switch ports ok?

6c) zero any errors

6d) check SFP light (signal loss) levels

6e) check for LLI (lost link indicator)

6f) check that expected WWPN of initiators and targets are all present
