Dataprotector Poor tape reset

The other day at work a whole bunch of backup jobs failed a in the process all the used tapes had been marked red in dataprotector with a "POOR" quality label.
As a result, that tapes are unusable until the retension time expires.

Luckily, there is something you can.

Open a command screen on your DP server and browse to the folder c:\Program Files\OmniBack\bin. Probably best put it in the path, so you can execute commands from anywhere.
Anyway, with the command omnimm you can do all tape & drive related manipulations, perfect for scripting purposes.
One of these options is resetting the tape quality. To do this, execute this command: omnimm -reset_poor_medium . Not even a second later, you'll get a message: Reset poor flag on medium .
The tape is now back in "GOOD" quality and ready to use.
