  Breakdown:

 

   kfbh.endian 

     kf3.h   /* endianness of writer */

       Little endian = 1 

       Big endian = 0

 

   kfbh.hard   

     kf3.h   /* H.A.R.D. magic # and block size */ 

 

  kfbh.type

    kf3.h    /* metadata block type               */

 

  kfbh.datfmt

    kf3.h   /* metadata block data format        */

 

  kfbh.block

    kf3.h   /* block location of this block      */

      blk -- Disk header should have T=0 and NUMB=0x0

      obj -- Disk header should have TYPE=0x8 NUMB=

    blk and obj values are derived from a series of macros in kf3.h.  See

    "KFBL Macros" in kf3.h for more information.

 

  kfbh.check

    kf3.h   /* check value to verify consistency */

 

  kfbh.fcn

    kf3.h   /* change number of last change      */­

    

  kfdhdb.driver

    kf3.h   /* OSMLIB driver reserved block  */

       If no driver is defined "ORCLDISK" is used. 

     

  kfdhdb.compat

    kf3.h   /* Comaptible software version   */

      example: 0x0a100000

      You get:     

          a=10 1=1 so 10.1.0.0.0

 

  kfdhdb.dsknum

    kf3.h   /* OSM disk number               *

      This is the disk number.  The first disk being "0".  There can be up to

      ub2 disks in a diskgroup.  This allows for 65336 disks 0 through 65335.

 

  kfdhdb.grptyp

    kf3.h   /* Disk group type               */

 

  kfdhdb.hdrsts

    kf3.h   /* Disk header status            */

      This is what is used to determine if a disk is available or not to

      the diskgroup.  0x03 is the correct value for a valid status.

 

  kfdhdb.dskname   /* OSM disk name       */

  kfdhdb.grpname   /* OSM disk group name */

  kfdhdb.fgname    /* Failure group name  */

  kfdhdb.capname   /* Capacity grp, unused*/

    kf3.h

 

  kfdhdb.crestmp   /* Creation timestamp            */

  kfdhdb.mntstmp   /* Mount timestamp               */

    kf3.h To derive the hi and low time`from an unformated dump use the

    "KFTS Macros" in kf3.h.

 

  kfdhdb.secsize

    kf3.h   /* Disk sector size (bytes)      */

      This is the physical sector size of the disk in bytes. All I/O's to the

      disk are described in physical sectors. This must be a power of 2. An

      ideal value would be 4096, but most disks are formatted with 512 byte

      sectors. (from asmlib.h)

 

  kfdhdb.blksize

    kf3.h   /* Metadata block (bytes)        */

      

  kfdhdb.ausize

    kf3.h   /* Allocation Unit (bytes)       */

 

  kfdhdb.mfact

    kf3.h   /* Stride between phys addr AUs  */

    

  kfdhdb.dsksize

    kf3.h   /* Disk size in AUs              */

      Mulitply by AUs to get actual size of disk when added. 

        

  kfdhdb.pmcnt

    kf3.h   /* Permanent phys addressed AUs  */

      Number of physically addressed allocation units.

 

  kfdhdb.fstlocn

    kf3.h   /* First FreeSpace table blk num */

      Used to find freespace.

 

  kfdhdb.altlocn

    kf3.h   /* First Alocation table blk num */

      Used to find alocated space.

 

  kfdhdb.f1b1locn

    kf3.h   /* File Directory blk 1 AU num   */

      Beginging for file directory.
