Problem with pathing / drive definitions

[Lizard]

Hello all

I currently have a TSM Master server connected to a 3584 library running 3580 LTO3 tape drives. I have two TSM servers connected to this master server, and tape drive paths are defined in the system and all works okay.

I am planning an expansion by adding some 3580 LTO4 tape drives. I have found though that if I installed the 3580 driver in windows which supports the LTO4 drives (my current installed driver doesnt support the LTO4 drives), then all my pathing disappears, and all I see in drive definitions are identical qlogic hba names.

Are there anyway of preserving the existing pathing? or is it a case where I will just need to recreate the pathing from scratch?

Can you not use the newer driver just for the LTO4 drives?

No. I can't. It automatically updates the windows driver for the library as well as for the LTO3 drives.
