MIssing PATH: for drives

I ahve a LINUX Media server, and the drive path when i run a tpconfig shows missing. How do I get NB to see the paths once again?

Currently defined robotics are:
  TLD(3)     robot control host = nbuf1a

EMM Server = nbuf1a
 

  • Remove the drives with the missing paths, readd with device wizard.  Make sure when you select the media server, also select the robot control host if it is a separate server.

    This will restart ltid on both servers, so ensure no jobs are running.

  • You need to get the OS to see the 'missing' drives.

    Check /var/log/messages for errors, then use this command to check OS connectivity:

    # cat /proc/scsi/scsi

    Verify NBU sees devices via OS:

    # /usr/openv/volmgr/bin/scan

  • The OS sees the drives:

    [2:0:0:0]    tape    HP       Ultrium 4-SCSI   R500  /dev/st4
    [2:0:0:1]    tape    HP       Ultrium 4-SCSI   R500  /dev/st5
    [2:0:0:2]    tape    HP       Ultrium 4-SCSI   R500  /dev/st6
    [2:0:0:3]    tape    HP       Ultrium 4-SCSI   R500  /dev/st7

    [4:0:0:0]    tape    HP       Ultrium 4-SCSI   R500  /dev/st0
    [4:0:0:1]    tape    HP       Ultrium 4-SCSI   R500  /dev/st1
    [4:0:0:2]    tape    HP       Ultrium 4-SCSI   R500  /dev/st2
    [4:0:0:3]    tape    HP       Ultrium 4-SCSI   R500  /dev/st3


    I ran the scan, It looks like it sees all 8 drives too:

    frux0273:/usr/openv/volmgr/bin # ./scan

  • I removed them all and then ran a tpcautoconf -a... they all showed back in and online. Thanks you so much.

  • Excellent work.

    With drive issue, esp missing paths, often easier just to remove them and readd.
