who quickly answered my question and pointed me in the correct direction.

Here is my original question:

Here is the answer:

If you want 2 machines presenting 1, you want clustering and this is not a
capability of LSM. LSM will let you build multi-disk/striped/mirrored
volumes from a bunch of disks on 1 machine. You need TruCluster software,
licenses, special hardware etc. etc. to start up clustering.


Thanks again even though I should of known better:)
