Metrocluster question
I have a 2 node HPUX cluster which uses a 3rd physical server as the quorum server(currently running HPUX as well) for the cluster.
Currently all 3 machines reside in the same comms room, but we are planning to move 1 node to a second site. This gives us a problem of the quorum server having to be in one room which is bad.
I want to know if it is possible to use Linux to make the quorum server and to create an RDP image of the quorum node, so that we could do a bare metal restore of the quorum node at the second site if we lost the primary site/the site which must hold the quorum server.
How are other people that dont have 3 sites get around the issue? - I know you can have 2 quorum servers at each end 'active', but I am concerned that may risk split brain if the connectivity between sites is broken.
any help appreciated. thanks

Re: Metrocluster question
Yes Linux is a valid platform for quorum server. I'm certain that product runs on Red Hat and probably Suse.
Your plan will work.

Re: Metrocluster question
The only disaster-proof way of doing this is hosting the Quorum Server at a third site, preferrably in a local cluster, with redundant telecommunication links to your two data centers. Think of this as a triangle, but it can be a really, really expensive one. This is not always possible, for cost and practical reasons.
