Good Morning Sergey,

 

The answers are it depends.

 

You have to make sure that you do not have the system try to load a LTO-3 tape into a LTO-2 tape drive.

 

A simple method if you have the IBM 3584 tape library is to define a new virtual library for the LTO-3 tape drives and treat them as two libraries in netbackup. That is a new storage unit, and the lto-2 and lto-3 tapes and tape drives would have different media settings (for example hcart2 and hcart3).

 

We have not tried it yet, but it would seem that one could have one virtual library with two different storage units with the tape drives and tape media set to different media settings. One would also require bar code rules to assign new tapes to the correct media settings. I am guessing that this would require different volume pools.

 

It would be nice if netbackup could handle the fact that the tape drive can write to two different media types, and read three different media types.

Hello,

We have IBM tape library with LTO-2 drives and planing to add LTO-3 drives and LTO-3 tapes to it.

How to configure netbackup infrastructure to use different drive types with single robot?

Does Drive wizard detect new drives correctly or we need add drives manually?  Is  new volume group fot LTO-3  needed for tape operations?

 

Thank you very much, Sergey
