In the following example, the host has a failed bootdisk (c0t0d0). Fortunately, the system is using DiskSuite, with a mirror at c0t1d0. The following sequence of steps can be used to restore the system to full redundancy.

screen not found
Can't open input device
Keyboard not present. Using ttya for input and output.
