Solaris Common Messages and Troubleshooting Guide

SYSTEM HANGS DURING BOOT

Cause

When the user boots a system, it hangs after the boot up messages "root on," "swap on," and "dump on." After the system displays these messages, the LEDs will flash and the system hangs.

This is the result of an earlier fsck that deleted devices under the /dev directory. Check for the /dev/console device and if it is missing, make one.
