On a SGI's ARCS systems all disks (even CD) must have a IRIX volume header vh(7M) and partitions. A typical IRIX bootable volume consists of the following partitions:

Partition # Use
0 Root Filesystem partition
1 Swap partition
7 Volume Body partition
8 Volume Header partition
10 Whole Disk partition

The Volume Header partition must start at the first sector on the disk. It contains the disk label in the first sector, and a rudimentary filesystem (readable by the PROM Monitor) in the rest of the partition.
