I followed some step before to come here, as this picture shows.... I have 2 robotics libraries, but I can work with only one ( D2D System Backup). I can´t do anything with my tape library ( HP MSL2024) , in Devices ' Window of Backup Exec 12.5, the slots of this device appears like "Unknow Media".
Yes I do. This is the message more and less : "You can't perform an inventory/erase... whatever 'cause the robotic library is disable, offline or paused"...
A MSL 2024 will appear in the Device Manager list as an Unknown Medium Changer. This is normal.
From your screenshoot, it appears that you have 2 tape drives in your MSL 2024. Did you enter an additional Library Expansion Option (LEO) licence for the 2nd tape drive? Out of the box, BE 12.5 only support a tape library with 1 tape drive. For each additional tape drive in the library, you will need to purchase a LEO licence.
That is another issue, I have another robotic library (D2D System Backup) and to test if I can work my tape library I disable D2D in Backup Exec but nothing, I don't know why I can´t work with the Tape Library if only I have enable that robotic library.
In other hand, I tried to install LEO, but I just licensed it, I haven't found how Install it....
