  • How about device path, any changes ?. See to /var/adm/messages the log errors, or create directory log in /usr/openv/volmgr/debug/ltid.


  • Add VERBOSE entry in /usr/openv/volmgr/vm.conf.

    Restart NBU.

    Media manager errors will be logged in /var/adm/messages.

    tpconfig -d simply gives configuration info. vmoprcmd -d will give status info - robotic problem will show drives in AVR status.

  • I restarted the NBU. Here is the details


    MM_SERVER_NAME = netbak
    MEDIA_ID_BARCODE_CHARS = 0 8 1:2:3:4:5:6

    MM_SERVER_NAME = netbak

  • Please add VERBOSE entry to vm.conf. File will look like this after you have added the line:

    MM_SERVER_NAME = netbak
    MEDIA_ID_BARCODE_CHARS = 0 8 1:2:3:4:5:6

    Then stop/start NBU. If the library goes down again, the reason should be logged in /var/adm/messages.

    The above vmoprcmd output shows all UP and working - drives in TLD control (tldd communicating with tldcd).

  • Abu,


    I am having a problem between NetBackup and a Sun SL48 tape library.  It has been an on going problem for at least a year.  I my case I can power cycle the SL48 an restore NetBackups controll.


    Note: Before I power cycle the library, I wait until all NBU jobs have finished or are waiting on a tape mount.  Then I use the library browser interface to manully remove any tapes from the tape drives and return them to the slot where they came from.  Then force a power cycle by pushing and holding the power button for about 10 seconds.


    have a good weekend,
