We have a Dell PowerVault 110T DLT1/VStape drive which has recently started to fail backups with the following error message:
"The operation was not performed because no unused media was available."
After closer inspection it appears the tape drive feeds the tape as normal, rewinds the tape.. And then Ejects the tape... Almost as if it's a cleaning tape..
Theres no error lights or cleaning lights on the drive.. And even after running the cleaning tape, it seems to make no difference.
We use NTBackup over most of our sites, and have nothing but trouble with it..
However, I have never seen anything like this before, and shot of changing the drive I dont know where to start!
