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
