Level 4

[root@LINUX ~]# /usr/openv/volmgr/bin/vmoprcmd | grep -i missing

Does the drive show using in the scan command?

May need to restart the media server and run device configuration wizard.  But first the OS has to see drive.

Will is right. The OS has lost connection to the drive.
You need to check physical connection and OS config.

Nothing can be done from NBU side.

The command scan use SCSI command to identify the robot and drives at OS level.

If the drives detected at OS level then it should show in scan output.

Kindly cross check that drives are showing at OS level and fix the issue at OS level.

If it showing at OS level but not in scan command output then update the device mapping file

1. ensure drive is visible to OS

2. scan drive into netbackup


if you are using tpautoconf, you may be able to use tpautoconf -replace_drive


I have had occaison when a server got connected to an offsite ACS robot, and could not see it's local drives.

If you start tpconfig and display the robots on the media server, see if there are any extra ones. 

I was able to resolve my issue by removing the inappropriate robot, and stopping and restarting netbackup.

The local drives reattached.

NetBackup on Solaris 11, writing to Data Domain 9800
duplicating via SLP to LTO5 in SL8500 via ACSLS

You may go to Devices->Drives and delete all drives from there.

  1. Now you can rerun the Device configuration wizard and follow the steps. There you get to know if drive is being scanned at OS level or not.
  2. Or you can run "tpautoconf -a" , which will reconfigure all drives again, and can resolve your missing drive issue.

Best regards !!
