We come across a weird problem at one of our customer sites. When tape are in the library they are all recognized with their bar code. Those will appear nicely in the inventory. Then the next day i can happen that some tapes do not register in the inventory with their bar code's but are named Tape1 and Tape 2. It happens to previously empty tapes but also to tapes which are uses for backup just last night. The only workaround now is to erase the tape then it will suddenly reads its bar code again. Now for empty tapes this is not a problem but for tapes used in the backup it is a problem. This is also the case with tapes that where uses in a backup and then send off site, en when put in the library again they register as TAPE1, TAPE2 ect.
This weird behaviour also impacts the backup cause sometimes this happens to tapes which are in a pool and by renaming them Veeam does not reconize them any more which results in a fail backup due to lack of tapes (if they where not renamed the number of tapes would be sufficient to make the backups).
Anyone has the weird tape handling seen before?
