We are running two large tape jobs with ~10TB to two LTO-5 libraries.
Each job is using ~8-10 tapes.
Every once in a while the job does not want to use all of the tapes provided.
The error shown is "Loaded tape has unexpected media ID than expected. Most likely, this is caused by duplicate barcode. Please insert the correct tape."
There is no duplicate barcode. The tape is in the catalogue only once.
When I erase all the tapes from within Veeam using "short erase", the job runs flawlessly.
Problem is: When the error happens the job is already half done, waiting for a "correct" tape and blocking the drive. So we cannot do an erase. I have to stop the job and loose 1-2 days.
I opened a case on that #01987531
Support only provides the option to format the tapes using vendor tools. But as the short erase does is: there must be an easy way to correct the problem in Veeam's catalogue and allow me to continue my Jobs.
