When I've done this in the past its been a pool export, reconfigure storage, pool import procedure. In my dark PowerPath days I recall PowerPath couldn't handle the using the emcpower# disk name. You had to format the emcpower device and create you're zpool on the "emcpower1a" slice. This may have changed in the newer versions of PowerPath (the last version I ran was 5.0.0_b141). I've since switched to using Sun MPxIO for multipathing. Its worked fine so far its certain to support you're ZFS config. Just export you're pool, run the "stmsboot -e" commmand, reboot, and re-import you're pool. -Alex _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
