Multiple hosts writing to the same pool won't work, but you could indeed have two pools, one for each host, in a dual active-passive arrangement. That is, you dual-attach the storage with host A talking to pool A and host B talking to pool B. If host A fails, it can 'zpool import -f B' to start serving up the B data. HA-ZFS (part of SunCluster 3.2) will automate this, but for now you can roll your own along these lines.
