Tape Drive is not assigned to the media server

I have 4 tape drive on media server was running fine before but one day 1 particular drive never been used anynmore by the backup. Then I check like the following: 

D:\Program Files\Veritas\Volmgr\bin>vmoprcmd -d

                                PENDING REQUESTS

                                     <NONE>

  0 ESL02_Drive9          No       ebs5-bck.m1.com
  1 ESL02_Drive7          No       -
  2 ESL02_Drive8          No       ebs5-bck.m1.com
  3 ESL02_Drive10         No       ebs5-bck.m1.com

So it is not assigned to the Media server. How can I fix this?

The media server is running Windows 2008 and NetBackup version is 7.7.1. 

 

Thank you very much.

Re: Tape Drive is not assigned to the media server

The config clearly shows 3 tape drives in robot controlled by media server ebs3-bck and 1 tape drive in robot controlled by media server ebs311bck. NetBackup did not magically change this all by itself. Someone in your environment did this - either manually or by running the device config wizard. I also noticed that scan only picked up 2 tape drives. It could be because the other 2 drives were in use. You should only proceed with changes/reconfiguration when no tape drives are in use as NBU will need to restart services. Firstly delete the remote robot 3 on this media server as well as drive ESL02_Drive7. Allow NBU to restart services on the media server. You should now be left with robot 1 and 3 tape drives on this media server. Start the Device Config wizard. Select robot control host ebs3-bck and this media server. See if the wizard picks up all 4 drives in the same robot. If so, complete the wizard and allow restart of services. If device config is good after this, double-check STU config to confirm that it is configured for 4 concurrent drives. If Device config wizard only sees 3 tape drives in robot 1 as per previous (incorrect?) config, you need to check hardware config.

Re: Tape Drive is not assigned to the media server

Please show output of these commands on the media server: scan tpconfig -l

Re: Tape Drive is not assigned to the media server

Do you storage unit(s) have 4 tape drives all together ?

Is the tape drive OK in library interface ?

The standard questions: Have you checked: 1) What has changed. 2) The manual 3) If there are any tech notes or VOX posts regarding the issue

Re: Tape Drive is not assigned to the media server

There could also be a 'stuck' device allocation.

Run this command when no backups are running:

nbrbutil -ResetAll

Thanks all for the reply.

I will try the other command you suggest me tomorrow, because I only have downtime tomorrow, the media server is quite busy.

Re: Tape Drive is not assigned to the media server

You have 2 robots - 1 with 3 drives and another with 1 drive. This means 2 storage units. If backups and/or duplications are set for STU robot-1 then the drive in robot 3 will never be used. Hopefully you have created a STU group with both STU's? Check that all backups and/or duplications are set for STU group.

Marianne, Thank you very

Marianne,

 

Thank you very much  for analizyng. We have 2 Tape Libraries in difference sites, actually the ESL02_Drive7 should be on the robot 1 (not 3). I think from the report the ESL02_Drive7 went to robot 3 which is not correct. Just found out according to a colleague he did delete that drive and put it back due some problem. It seems it went to other Tape Library.

So I should delete the tape and add it backup again right? I will do it by today I let you know the result.

 

Regards,

 

Iwan

Re: Tape Drive is not assigned to the media server

Marianne, 

 

Yes someone ( a colleague) change the configuration, I think from the last reboot somehow the Windows could not see the tape drive, then he tried to delete and put it back, somehow it went wrong. 

I follow your advice, Now it is working fine. Thank you very much!
