Did you run an inventory or catalog of the tape once you put it back in (Tape2)?  It should be recognized but an easy way to update Veeam is running this.

Hello @jmaticurena 

Welcome to the community. As @Chris.Childerhose mentioned, you need to inventory the tape.

Did you eject the tape via the button at the drive or with the eject or export function in Veeam?

I explain: the tape that was on was removed with the drive button, when the other tape was inserted and it read the content of the previous tape, it was removed with the Veeam Eject.

Did you inventory the tape like I mentioned once it was put in?  You may need to do that to accomplish your task.

After removing the tape, he put it back in and ran the inventory and it didn't recognize it, in fact he put in the tape that was there before and he did read it.

Well, if you need data off the tape then I suggest opening a Support case at this point.  If the tape has Veeam data on it then they will be able to check the logs, etc. to determine how to address it.

Update: today, after removing the tape that it didn't read, turning off the tape drive, turning it on and putting the tape back in, VBR recognized it and went online.

Could it be something in the unit? Well, neither the Veeam server nor the server where the tape drive is connected was ever turned off.

Could be a problem with the tape unit possibly.  If you can run any utilities on it to test it, I would and replace if necessary.

Hi @jmaticurena -

I just wanted to follow up on your tape issue. It appers from your lost comment you may have resolved your tape recognition issue? If so, or if you feel another of the comments above helped you, could you select one as a ‘Best Answer’ to benefit others who may come across your post who are experiencing the same tape issue?

Thank you.
