Hello Experts,
I am trying to setup clustering and one of the process that needs to be done is the configuration of Quorum Disk. My question is...do I need to put this on a seprate disk and also on a separate bus? Or can I configure this on a logical drive? For example, if I have a 20 GB HD and I split 15 GB for the C and 5 GB for the Q where the quorum is to be located. Is this okay? The entire physical drive will be raided onto a second physical drive.
Any advice or suggestions is greatly appreciated. As always, thank you for your time on this matter.

merowinger,
Just read your first comment and in the process of pulling the link, but are you suggesting then that the quroum resource (quroum disk) be somewhere external of the nodes and not reside in the first node on any other nodes in the cluster? Maybe this was the reason that when I intentionally tunred off the first node of my test cluster that the second node didn't work due to the fact that the quroum resource was located on the first node.
Again, thank you for your time on this matter.

yeah the quorum disk must be external (scsi , fibrechannel), dynamic...
Here's a nice checklist:

merowinger,
So...the quorum resource (or quorum disk) must be a disk that is separate from where the O/S resides and must be on a separate bus. Also, it cannot be a shared drive like the one that one would create on explorer? So, my options are iSCSI, Fiber Channel or a HD on a separate bus. Is that correct?

yes that's right!

merowinger,
Okay...so I can allocate the quorum resource onto a SAN with iSCSI with 1GB of HD for a 2 node cluster? And if my node 1 goes down, node 2 should function since the quorum is on the SAN. Is that a right assumtion?
Again thank you for your time.

Again thank you for your time.
yes 1GB is enough!
U should test if both nodes have access to that external disk..
if this is so...u should could make a failover, so the other node should be able to access the SAN

merowinger,
Need further clarification. If the Quorum Resource is residing on a SAN virtual drive and that drive is defined on Node-1 of that cluster (my goal is to configure an Active / Passive cluster with two nodes)and that Node-1 goes down, that in turn will bring the cluster down cause Node-2 wouldn't know where the quorum resource is. Does this mean that I need to go into Node-2 and repoint as to where the quorum resource is? If so, how can I make this automatic so that when Node-1 fails, Node-2 should continue to function and pickup the functions that Node-1 was doing. Or I am totally confuse here?

If u take a internal disk as quorum disk...one of the nodes cannot connect to this ressource
