 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=<disknumber>

   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 so10.1.0.0.0

 

 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  /*Mounttimestamp              */

   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.
