    Commands that you can use on Linux without even featuring netbackup to see if output shows your tape drives.

    # hwinfo --tape

    # cat -s /proc/scsi/scsi

     

    Netbackup featured commands to show output:

    # scan

    # tpconfig -l

     

    What version of Linux and kernel you running?

    And list hardware library and tape model please.

    You need to check that the OS is seeing devices with:
    # cat /proc/scsi/scsi

    If devices are not seen, you need to check zoning and confirm OS drivers.

    Nothing to be done in NBU if OS cannot see devices.

    PS: 
    I see in above output a reference to RHEL 4.4.7?
    Is this the same in /etc/redhat-release?

    According to NBU OS SCL, NetBackup 7.5 and later does not support this Operating System on this CPU Architecture.
    You need RHEL 5 or 6.

    Expect to see some tape devices under there...

    What does the output of the following give

     

    # scan

    # tpconfig -l

    # ls -al /sys/class/scsi_changer/

    # ls -al /sys/class/scsi_tape/

    If you are expecting to see tape devices then the OS can't either.

    Sort that part out first before continuing from the NetBackup management side. So...

    Revisit Zoning of the backup host and the tape drives on your SAN switches and then check cable connections etc.
