Managed Disks in Windows 2003

While setting up windows cluster in 2003, my external array which is
logically partiotioned into P and Q appear as one disk group.
If i wanted to setup an active/active SQL cluster, how can i seperate into 2
groups, so that one node owns P and SQL instance 1 has data files on P and
the other node owns Q with another SQL instance owning Q. I didnt see a
managed disk dialog during the 2003 windows cluster instance.
Consult with your extenal array vendor documentation/support. It may be that your array cannot present virtual disks (like many high-end SANs can). This may mean that you need disk sets made up of different physical disks to present 2 "disks" to your cl
uster. eg physical disks 1, 2+3 are drive P, while physical disks 4 and 5 are drive Q. Don't forget that you'll also need a separate disk for the Quorum. So, in your configuration you'll need to have AT LEAST 3 separate disks to present to your cluster
. What sort of external array are you using?
|||MSCS looks at the physical layer, not the partition level. So you can have 4
partitions on a single disk, but MSCS will display this as one physical disk
resource. The only way to achieve an active/active configuration would be to
add another physical disk...can't be done with your current config.
