Can you please confirm the following:

Are you adding a new robot with LTO7 drives?
Or adding additional (LTO7) tape drives to existing robot with LTO5 drives?

You can do both with NBU - add new robot and new drives or just new drives in existing robot.

Your only limitation will be physical connectivity - you really do not want to zone too many devices to same hba and most media servers cannot really use more than about 4 drives simultaneously and still ensure good performance.

That is fine, (taking into account Mariannes excellent point about no drivers on a media server).  Just configure the new library as normal.

Although the new drives are in a seperate library, you may wish to make them and the media a different density (hcart, hcart2 etc ) than the LTO5 library, purely so it is a bit easier to spot which tapes are which.  It's optional, you would only /have/ to do this if the new drives were in the same library as the LTO5s.

Plan to replace the current lto5 tape library(MSL6060) from the media server, before the same media server need to configure with new lto7( tl4000)tape library after configured slowly move all backup to new lto 7 tape library.

so i can configure new lto7 library in existing media server which is already connected with lto5 and slowly i can decom the lto5.

Thanks you so much..
