Each of two nodes also has two (non-shared) internal disks which are
used for the root file system, swap etc. Each shared storage unit has
three disks, The device file names of the three disks on one of the two
storage units are c0t0d0, c0t1d0, and c0t2d0. On the other, they are
c1t0d0, c1t1d0, and c1t2d0.
NOTE Under agile addressing (see “About Device File Names (Device Special
Files)” on page 115), the storage units in this example would have names
such as disk1, disk2, disk3, etc.

Figure 3-21 shows the individual disks combined in a multiple disk
mirrored configuration.
