HP tape library MSL8096 after splitting into 2 logical libraries, server B: sees the library twice

[behlaucarlos]

Hello HP Gurus,

we are having a HP LTO 3 Library MSL8096 with 4 LTO3 drives.

We configured the library into two logicial libraries.

The library is fibre connected to two servers.

Server A is running Windows 2012 R2 and seeing the library correctly with two drives.

Server B is running Windows 2003 and seeing the library double, with four drives.

Server B is running IBMs TSM Software and we want to migrate the old data into our new backup solution.

We are out of ideas, why the TSM Server B is seeing the library double.

The HP MSL 8096 is having its latest firmeware version.

For your ideas, hints and tips many thanks.

Best regards

Carlos Behlau
