2.2 Disk Partitions

2.2.2 SunOS 5.X

SunOS 5.X defines the partitions as numbers, rather than names. Also, instead of calling it a partition it's now called a slice. The root slice is then 0, slice 1 is swap and slice 2 covers the entire disk.

On a SunOS 5.X the disk might be formatted something like this:

# format sd0

format> partition

partition> print

Volume: nyssa

Current partition table (original):

Total disk cylinders available: 1866 + 2 (reserved cylinders)

2 backup wm 0 - 1865 510.23MB (1866/0/0) 1044960 entire disk

7 unassigned wm 1246 - 1865 169.53MB (620/0/0) 347200 /opt

where Flag indicates writable/mountable (wm) and writable/unmountable (wu).
