I have one master and 20 media servers in domain1 which are using 2 tape libraries (IBM 3573-TL, IBM ULT3580-HH7). Now I want to move 2 media servers to another master server. My question is, after moving the 2 media servers to domain2, will they still able to access domain1 tape libraries and images in those tapes?
If no, what changes i need to do in order to access those?
To expand on @RiaanBadenhorst 's post:
A master server has 100% control of ALL resources - devices such as tape library, Tape drives, Tapes (media), Media Servers and backup images.
It is impossible to share any of these across masters.
If you partition a library to give access to a new master server, you will need to assign dedicated tape drives and new media to this partition. Any media belonging to the old master will be seen as new and will be overwritten.
Seeing that you have 2 tape libraries, you can remove one tape library from the original master, but you will need to properly remove devices and media servers. All tapes with valid images will need to be removed from the library and ownership assigned to remaining media servers.
A media server can only have one master/EMM server. So, it will only have access to backup images on it's current (new) master.
When you move a media server to a new master, it can no longer access images or tapes on the old master.
'Domain split' can be done with catalog manipulation tools - this is a paid-for consulting exercise.
