Missing path
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.
