You could try these commands.

tpautoconf -replace_drive IBM ULT3580-TD6 KAJ8 -path /dev/rmt26.1

tpautoconf -replace_drive IBM ULT3580-TD6 KAJ8 -path /dev/rmt30.1

Looks like it’s dual path as the same drivename /serial number appears but with different paths.

You need to restart volmgr afterwards on the media server with the drives.

/usr/open/volmgr/bin/stopltid
Wait a min
Then
/usr/open/volmgr/bin/ltid -v

Don’t do this with any jobs running, it will kill them.

tpautoconf -report_disc should then be empty.

Not sure if this is related to the drive swap, as usually you would have a ‘missing device’ - but then I don’t know the history of exactly what has been done.

If this doesn’t work, I’d just delete the missing devices and rerun the wizard to add the drives back in that way.

Hi,

We are getting the Missing path Issue.

The serial number of drive from tape library is not matching with the Serial number at the OS end.

Hey

well try to run 

tpautoconf -report_disc

to see the discrepancies, and then the best would be to remove the drive and run configuration storage device wizard from GUI

make sure with scan command that os see all needed drives, robots...

 

Hi,

We need to remove the drives from the master Server or the Media Server.

If the serial number has changed, this would show as missing path I suspect as NetBackup tracks the drives based on the serial numbers.

Firstly, what has been changed, serial numbers don't change by themselves, either a drive has been physically replace/ swapped position.

tpautoconf -report_disc should show what is going on, then you can either just remove the drives and then re-add them with the wizard, or use tpautoconf -replace_drive <drive name> -path <drive path> to fix the config.

Hi,

Thank you much for the reply. I am new new to Netbackup.

Faulty Tape drive has been replaced few weeks back.
