P2V VM Master Server and the Robot Control Host
I have gone through the following documents but couldn't find exactly what I'm looking for.
Support for NetBackup 7.x in virtual environments:
Enabling multiple robotic paths from a single media server:
All Windows 2008 R2 SP1
1x Master Server 7.5 - Physical host, FC Robot Control host, no access to tape drives
2x Media Server 7.5 - Physical host, FC SSO shared tape drives, no access to Robot Control
For one of our sites we are contemplating in doing a Physical to Virtual conversion (P2V) for the Master Server to become a VMware ESX VM.
The Master Server has never been used as a Media Server, which makes it an ideal candidate to be virtualized; it has no Storage Units, Disk Pools, Storage Servers, etc.
However, it does currently serve as the Robot Control Host for the tape library.
I'm trying to figure out the best thing to do with the Robot Control.
Shall I use some kind of physical device pass-through/RDM to present the Robot Control path to the VM Master Server? If this works, how would vMotion/migration from one ESX host to another affect this configuration?
Or, I could simply let one of the two physical Media Servers be the Robot Control Host.
But then, if the server fails, the other Media Server will not be able to do any backups.
If I present the Robot Control path to both physical Media Servers, I could designate one of them to be the Robot Control Host, and if it fails, I could MANUALLY make the remaining Media Server the Robot Control Host.
I don't suppose the failover of the Robot Control could be done automatically without manual intervention?
The document I linked to only talks about multipathing on a single Media Server.
What would you think is the best thing to do in this situation?
Any input would be appreciated.
