Oh, sorry, prtpart appears to be a part of FSWpart package (it's a package for accessing ext3/ntfs filesystems), not the part of solaris distribution. Anyway, "/usr/sbin/format" is a stock utility, and should help you just fine. By the way, if you want to try out zfs without much hassle, in the beginning you can try making a zfs pool on simple files, not messing with file systems, see for example this tutorial: http://flux.org.uk/howto/solaris/zfs_tutorial_01 Cheers, Einar
