Here’s a quick way to find out what hardware is installed in your Solaris system, including RAM, CPUs, PCI cards, and external devices. The output will usually include the size of each memory chip in the system.
The one trick to using this command is to make sure you use the backtick instead of a single quote around the
uname -i. The backtick is typically shift tilde and forces the command between the backticks to be executed and substituted in to that part of the command.
prtdiag actually displays system diagnostic information. I’ve used this on Solaris 7 through 10. The best parts is you do not even need to be root to execute this.
For more info on
prtdiag check out the man page.
