DKINFO(8)                   System Manager's Manual                  DKINFO(8)



NAME
       dkinfo - report information about a disk's geometry and partitioning

SYNOPSIS
       /usr/etc/dkinfo disk [ partition ]

DESCRIPTION
       dkinfo  gives  the  total  number  of  cylinders, heads, and sectors or
       tracks on the specified disk, and gives this information along with the
       starting  cylinder  for  the  specified  partition.  If no partition is
       specified on the command line, dkinfo reports on all partitions.

       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 iden-
       tify  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.

EXAMPLE
       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
