2.7.3 Using the prtconf Command
Similar to the show-devs command run at the ok prompt, the prtconf command
displays the devices that are configured.
The prtconf command identifies hardware that is recognized by the Solaris OS. If
hardware is not suspected of being bad yet software applications are having trouble
with the hardware, the prtconf command can indicate if the Solaris software
recognizes the hardware, and if a driver for the hardware is loaded.
2.7.3.1 Options
TABLE 2-14 describes options for the prtconf command and how those options can
help troubleshooting.
The following example shows output for the prtconf command.
