The disk specification here is a disk name of the form xxn, where xx is the controller device abbreviation (ip, xy, etc.) and n is the disk number. The partition specification is simply the letter used to identify that partition in the standard UNIX system nomenclature. For example, `/usr/etc/dkinfo xy0' reports on the first disk in a system controlled by a Xylogics controller; `/usr/etc/dkinfo xy0g' reports on the seventh partition of such a disk.
A request for information on my local disk, an 84 MByte disk controlled by a Xylogics 450 controller, might look like this:
#/usr/etc/dkinfo xy0 xy0: Xylogics 450 controller at addr ee40, unit # 0 586 cylinders 7 heads 32 sectors/track a: 15884 sectors (70 cyls, 6 tracks, 12 sectors) starting cylinder 0 b: 33440 sectors (149 cyls, 2 tracks) starting cylinder 71 c: 131264 sectors (586 cyls) starting cylinder 0 d: No such device or address e: No such device or address f: No such device or address g: 81760 sectors (365 cyls) starting cylinder 221 h: No such device or address #
