Hello,
We are trying to setup a BE 2012 ( evaluation version ) to allow data backups on to tape drives.
Running BE 2012 on windows 8 server.
We have a Dells PV LT2000 connected to the server via SAS interface. We have a Robotic library with 12 LTO6 tape drives .
Under Slots , I can see the tape drives labelled with barcode labels , however tape drives are showing "0 bytes capacity"
Things I have checked/done :
* Tape drivers are installed.
* Autochanger drives are native to Windows , hence shows Unknown Autochanger device in Device Manager
When i try to clean the Tape Drive , it gives error. Export/Import and "Inventory now" both give errors.
Before we installed Windows 8 on the server , it had linux with Baculla. I had labelled Tape drive then and ran some checks on the tape which were a success.
Post that we decided to drop Baculla and go ahead with BE 2012. However , I am unable to make tape work with BE 2012
Followed tape troubleshooting steps mentioned in the link and all seems to be fine.

I am not sure if I missed out anything or the issue is due to using bacula on tape drives before putting then on BE 2012.
If yes , how do i change it default ?
I have attached screen shots in the thread.
Any help will be appreciated.
Thanks

...there is no multipathing with tape drive...just make sure your configuration from a hardware perspective is correct.
Thanks!

Yes , tape does not support multipathing :)
Okay , Seems the issue is now fixed .
* I can see space of all the tape cartridges
* I was able to write 400mb of data and now testing with data size of 700 GB
--> What we did
* Removed 1 SAS cable and rebooted both tape and Media server ( do not know the order of reboot )
* I was now able to see 1 tape drive in Device Manager . However , it kept going offline.
All operations gave following error :
The job failed with the following error: Physical Volume Library Robot not found.
I was unable to see media changer in the device manager.
Scan for hardware changes didnt show autochanger as well
So I removed all tape drives using BE driver utility since BE still showed 2 tape drives . Rebooted the server.
Installed drivers again and rebooted again. I was now able to see autochanger , however kept getting above mentioned error.
After ensuing all drivers are updated and correct , i rebooted Tape and media server in the respective order.
Post reboot i was able to see space for all cartridges and was able to write to tape.
I am not sure whether it was 2 paths or the order of reboot that solved the issue.
Will work to find out in next few days .
Thanks everyone for their help to solve the issue.

Alan
