Thanks... very helpful. I noticed though that once a disk is formatted or put into a zpool the cyl no. is no longer given, but then the size is shown I did also find a diffeent answer too. `iostat -En ' Appears to give both the names and the sizes. But not sure it would still be useful in the case you describe. _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
