Using prtdiag to troubleshoot system problems

The prtdiag command on Solaris systems is both a script and an executable. The script, /usr/sbin/prtdiag, does a little fact checking -- such as whether your "uname -i" command yields a proper response; it should be your platform designation (e.g., SUNW,Sun-Fire-V240) and then runs the "real" prtdiag from its /usr/platform location. On a Sun Fire V240, for example, that location should be /usr/platform/SUNW,Sun-Fire-V240/sbin/prtdiag. The /usr/platform/`uname -i`/sbin/prtdiag command should work on any system. The command at this location is the binary that collects the information that prtdiag displays.

Even without its verbose (-v) option, prtdiag provides a lot of information on your system's components, including a status indicators such as "okay" and "online" for various system components. The output shown below is a portion of the prtdiag output, showing the status of I/O devices. It took me a while to realize that "MB" represents the motherboard.
