NAME

     /usr/mdec/sgivol -- configure SGI Volume Header


SYNOPSIS

     /usr/mdec/sgivol [-fq] device
     /usr/mdec/sgivol [-fq] -i [-h vhsize] device
     /usr/mdec/sgivol [-fq] -r vhfilename diskfilename device
     /usr/mdec/sgivol [-fq] -w vhfilename diskfilename device
     /usr/mdec/sgivol [-fq] -d vhfilename device
     /usr/mdec/sgivol [-fq] -m vhfilename vhfilename device
     /usr/mdec/sgivol [-fq] -p partno partfirst partblocks parttype device


DESCRIPTION

     The /usr/mdec/sgivol program prepares an SGI Volume Header to be used to
     boot NetBSD.  The SGI PROM is able to load executables within the header,
     which in turn are used to load the kernel from another file system.


OPTIONS

     The following options are available:

     -f      Force the operation.  Do not ask the user before proceeding.

     -h      Set the size of the newly initialized volume header in blocks.
             One block is 512 bytes.  The default volume header size is 3135
             blocks (1.53MB).

     -q      Suppress output.


PARTITION TYPES

     The numerical partition types for the volume header include:

                 0:  Volume Header
                 1:  Replicated Tracks
                 2:  Replicated Sectors
                 3:  Raw
                 4:  BSD4.2 file system
                 5:  SysV file system
                 6:  Entire Volume (all disk blocks)
                 7:  EFS
                 8:  Logical Volume
                 9:  Raw Logical Volume
                10:  XFS
                11:  XFS Log
                12:  XLV Volume
                13:  XVM Volume


EXAMPLES

     To display the existing volume header and partition table on disk
     ``sd0'':
           sgivol sd0

     To initialize a new volume header 42 512-byte blocks large on disk
     ``sd0'':
           sgivol -i -h 42 sd0

     To copy a file boot from the volume header to local file /tmp/boot on
     disk ``sd0'':
           sgivol -r boot /tmp/boot sd0

     To copy a local file /usr/mdec/ip2xboot to the volume header as boot on
     disk ``sd0'':
           sgivol -w boot /usr/mdec/ip2xboot sd0

     To delete the existing file boot from the volume header on disk ``sd0'':
           sgivol -d boot sd0

     To move (rename) an existing file file1 to file2 in the volume header on
     disk ``sd0'':
           sgivol -m file1 file2 sd0

     To change partition 0 to type 4 (BSD4.2) beginning at block offset 3200
     and continue for 28000 blocks on disk ``sd0'':
           sgivol -p 0 3200 28000 4 sd0
