We used to have an MSL8096 with one logical library connected to HP-UX cell manager working fine. but after configuration of two logical library each with two tape library, Data Protector can not copy to more than one tape per session. It bring error message of cannot unload exchanger medium. Another logical library is being used Veeam and everything seems to be working fine as it can copy to more than one tape per session.
See below part of the copy job session.
