3.2 Disk Partitioning
3.2.3 IRIX 5.X
IRIX has the physical devices in /dev, with disk entries in /dev/dsk (block devices) and /dev/rdsk (raw devices) for each of partitions 0 --> 7, in the form dksXdYsZ. X, Y, and Z are numbers, with X starting at 0 for your default SCSI interface, Y starting at 1 for your first disk, and Z going from 0 through 7. Additionally there are raw device entries for the volume and volume header partitions, in the form dksXdYvol and dksXdYvh, respectively. for the root disk you can also reference the root device as /dev/root and /dev/rroot, for the block and character devices, respectively. There are similar entries for swap, /dev/swap and /dev/rswap; usr, /dev/usr and /dev/rusr; and an access to the header, /dev/rvh.
