Sharing MSL library between 2 SANs
I know I can't use it at the same time, but I am only talking about doing a VMS backup at 6 pm and then a Windows backups at 12pm so they would never try to access the tape at the same time.
Thanks

Leaving the MSL accessible to both sets of servers all the time "MIGHT" work, but I think you'd likely run into issues.

Re: Sharing MSL library between 2 SANs
When you change your config as you say, it this a scripted operation? Or does someone have to manually change it everytime?
Forgive my ignorance, but what exactly does "cfgenable" do? I have never played with the SAN switches in my MSA.
Thanks for the info. :)

Re: Sharing MSL library between 2 SANs
Usualy backup application take care of this, the cel server is the one who decide which host should backup at that time and usualy manage the robotic controller.
If you plan to do backup manualy, all this management should be done by yourself, but there should not be any problem if the library in on the same SAN
You can found all the compatibility here:

Re: Sharing MSL library between 2 SANs
1. VMS can see and access the lib, Windows can't
2. Win can see and access, VMS can't
It's always safe to prohibit one of the servers the access. I'm not sure, but I guess this is far out of a supported solution. Because the systems may protest because of missing devices...
A good solution IMHO will be to give one server access to the robot and the first drive, the other server only access to the other drive. Best solution will be an integrated backup solution with management and storage agents.
Hope this helps!
Regards
Torsten.
