I can verify this behavior...

After tape ejects (an LTO-5 tape drive Quantum) it will appear online for backup exec 2014. If you do something simple like an inventory the tape it will immediately appear offline.

Basically right clicking to turn it back to "online" and it is fine.

Thank you for updating! Guess doing some sort of a PowerShell script to get tape back sounds reasonable?

Not sure what update you want from us @ this moment... It's not our issue so guys have been proposing workaround. Do you want us to incorporate one (PowerShell script, HOWTO guide or...)?

Hi

We all need a reliable workaround, one we can automate. Its a pain having to remember to manually inventory the tape after changing it and then bring the drive online.
As I said, my testing showed that this problem did not occur when BE is installed on the host server, only when running in hyper-v and using your tape redirector. Its very difficult for me to diagnose it any further.

So anyway you can help with something we can run automatically, would be really appreciated :)

We're re-investigating the issue and will probably provide an out-of-box PowerShell script to workaround this.

Hi

I'm getting the same problem using DPM 2012 R2 UR4. It happens after a while from 10-40Gb of written data to the Tape.

Is this the same problem as with BackupExec?

I have been wating the server for hardware faults and hardware disconnect but there is no problem there.

I'm running Windows Server 2012 R2 with tha latest updates and also running the latest version if TapeRedirector (7145).

Here are logs entries from the server:

I doubt it is the same cause/problem, the BE issue only occurs after a tape change. Its like BE does not realise the tape has changed and the next time it tries to talk to the drive it goes offline.

Hi,

It's not the same issue as that one with BE offlined tapes.

It looks like your system lost connection to that drive for some time (error 1167). Are there many such messages in the StarWind log file?

Are there any errors in the System log on the StarWind host?
Best regards,
Valeriy

Valery can it be anybody in the storage stack who has connection to tape drive and basically receives "media changed" ASC/ASCQ from tape drive instead of a customer whom we're supposed to send that over iSCSI?

According to the logs I've seen StarWind receives the "media changed" Unit Attention, and reports it to the client initiator.

It seems to be some time out issue at the BE side that leads to marking tape drives as offline.
I guess BE may use different time out settings for different tape drive connection types (SAS, SCSI, FC or iSCSI), there is a chance that BE recognizes tape drives mapped with iSCSI as connected to a local bus with short timeouts, so when a rather long delay with answer occurs it decides that the drive has gone offline...

Val,

Yes everytime I run a backup to Tape job from DPM 2012 R2 and after a while I get this exact same error in the Starwind host. There are no errors in the System log on the host, and I have alse checked for other hardware related errors or logs, but it looks normal, I have also been observing the device manager at the host during the failure and the Tape drive doesn't disconnect.

I've also used the latest drivers on both sides.

It was working before with the old version of TapeRedirector with the same setup.

I've also tried to tweak some iSCSI settings in the registry as suggested by Microsoft but no luck.

Any suggestions?

If it worked well for you with the older TapeRedirector, the first idea is to try it now to be sure it's the new TapeRedirector build's problem and not a hardware related issue...
