/dev/rdsk/* devices are character based devices, not block based. In general, character based devices have to be accessed serially (and don't do buffering), versus block devices which buffer and allow random access to the data. If you use: ls -lL /dev/*dsk/c3d1p0 you should see that the /dev/dsk/c3d1p0 device is a block based device and /dev/rdsk/c3d1p0 (via the first letter of the 'ls' output).
So while /dev/rdsk/xxx and /dev/dsk/xxx point to the same hardware, the access methods that are available via the two interfaces are very different. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
