BE2012 only uses 2 tape drives in Virtual Tape Library.

Background:

Our BE2012 connected with physical and vitual tape library (8 drives), we backup the data to VTL daily and export the monthly backup set to physical tape.

We've updated the BE2012 with Service 1a two weeks ago, everything goes fine. 

OS: Windows 2008 R2

Physical Library: Hewlett Packard MSL G3 Series Library. 2 slot

Virtual Tape Library: DataDomain DD670, 8 drives

No specific drives selected in all backup jobs, we checked all the drives in VTL.

Issue:

Last week, we encountered an issue about BE2012. the BE2012 only uses 2 drives only in VTL. Hence some of backup jobs keep queued and wait until the one of first two backup jobs completed. And the job status report "Ready no idle devices are available...."

We've called the support last Friday, and they finally replied me yesterday, what they did is try to remove the Windows Driver "Hewlett Packard MSL G3 Series Library" and use "Unknown Medium Changer" under "Device Manager" AND send me an email about close this case! 

After checking backup job run on yesterday, the same issue happened.

This morning, I've tried to remove that VTL, restart server again. BE2012 recognized the VTL and we configurated it again.

When we try to inventory the tapes in VTL, the BE2012 inventory process still use 2 drives in VTL.

Anyone have idea about this?

Now we have to move two backup jobs which takes over 12 hour backup to BE2010 server, however, this is only a short term solution for us.

BE2012 gives me a lot of time on troubleshooting and calling Symantec support. I miss BE2010!

 

 

 

  • Yesterday, the Symantec support called me and tried to figure out what was happening. 

    As troubleshoot with Symantec support, we finally deleted the VTL in data domain, restarted the services and tried to backup again. Sadly, the result still the same. Then he gathered the log for further investigation.

    After disconnected the line with Symantec support, I found that he did not cancel the testing backup jobs before deleting the VTL in data domain. Hence, BE2012 reported an error message for some active jobs in the tape drives which were not existing.

    And none of backup jobs can be started, all in "Queued" states. (I guessed the last 2 available tapes drives were occupied by the testing backup job.)

    Unfortunately, that was after office hour!!!! crying I stayed in office over time for troubleshoot by myself...

    And finally I had to logon to Database level to delete the orphan entries in "Device" table of BEDB database, and restarted the services.

    Finally BE2012 now can use all the tape drives in VTL now. I hope this is the last time I call for Symantec....
