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
