two hosts sharing the same data fia SAN?

[Anton Shterenlikht]

Hello

I've 2 separate freebsd boxes, each connected
vi fibre to a disk array. I'd like to have
a set of disk units to be read/write accessible
to both boxes. Seems this is not allowed with just
UFS. If one box mounts the disk units, then the
other box cannot mount them, i.e. seems the
disks cannot be mounted on both boxes simultaneously.
How can this be achived?

I've had a quick look at HAST, but it seems the
model their is different.

Thanks

Anton
