Cannot unload exchamger medius [90:64]

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.

Re: Cannot unload exchamger medius [90:64]

Hello!

 

That looks like a slight miconfiguration indeed.

When you say "two logical libraries each with two taoe libraries"-does this equal to four logical ones,

or have you simply added one more physical library and now you have 1 logical library per physical device,total 2?

If the same physical exchanger is configured twice in different logical devices and both logical are used in different sessions,the described behaviour may occur.

You might want to configure locknames in the DP's library properties and start with  ensuring that only one Multipath library is configured in DP per physical library.

Re: Cannot unload exchanger medium [90:64]

Hello StAlexendaer,

 

Sorry there was some mistake in my message. I was trying to mean we used to have one logical library with 4 tape drives and 96 slots. So after partitioning two library I have 2 tape drives and 45 slots for each library.

Not sure if the same physical exchanger is configured twice in different logical devices and both logical are used in different sessions.  Please advise me how to configure locknames in the DP's library properties and how to start with  ensuring that only one Multipath library is configured in DP per physical library.
