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
