    Yes you can. Try it (but make sure no backups are running as robtest takes access away from Netbackup whilst you are running it).

    hi revaroo,

    Just a small doubt.

    I am getting below error while unloading media.

    after this I have to run m d11 s23   ?

     

     

     

     

    unload d8
    Opening /dev/rtape/tape78_BESTnb, on the local host, please wait...
    Error - cannot open /dev/rtape/tape78_BESTnb (No such device or address)
    unload d11
    Opening /dev/rtape/tape81_BESTnb, on the local host, please wait...
    Error - cannot open /dev/rtape/tape81_BESTnb (Device busy)

    Please understand that NBU will not be updated when you move tapes around with robtest, and will therefore cause inconsistencies and errors. I do not think that tape can be moved from CAP directly to a tape drive, but as revaroo suggested - try it. WHY would you need to move tapes around like that?

    tapes can be moved from slot to slot?

     

    tapes can be moved from CAP to drive?

     

    why I am getting unload error?

    Again - WHY would you need to move tapes around like that? No such device or address means that the OS has lost connectivity to the drive. Verify at OS level that device exists. Check with commands such as scan. Device busy means that tape is in use. If this is SSO environment another media server is probably using it. Tape reservation can be viewed on the master server with vmdareq command.

    Unload is a tape drive command which causes it to be re-wound and popped from the drive

    This will often also make the robot out the tape back to the slot it came from

    You do not normally need to use the unload command - just m d11 s23 should be enough

    A s s will probably show that the tape is already back in s23 by the tome you ran the next command

    Only use unload if a tape is stuck in the drive - otherwise just use the m commands

    Thanks Mark,

    I just need to know whether I can move tape from CAP to drive?

    It would be robot dependant - robtest only sends a scsi command, if the robot allows it is outside of robtest.

    You will have to try it and see.

    The unload error: (eg)

    Error - cannot open /dev/rtape/tape81_BESTnb (Device busy)

    Would appear to be because you are trying to unload a drive that is busy.

    I cannot see why not - but NetBackup will be totally unaware of this movement other than possibly reading the tape header when it arrives in the drive - so you do need to put it into a slot and run the inventory at some point
