DP 10.90 wrong tape size

Hi All.

We have:

DP 10.90 on MS2019

Media type LTO-Ultrium 6.25Tb

8 of 42 tapes in DP Manager determined by 3Tb and backup ends with an error not enough space. But physically all tapes are the same and they are all 6.25Tb, all tapes are in the same pool.

in theory, DP should backup until the tape physically runs out, despite the displayed size in DPM, but this does not happen and we receive a request to mount the next media.

maybe there were some formatting errors with this 8 tapes by the previous administrator or any other reasons?

Please help to fix it.
