ipmitool differs a lot in Solaris and Linux. How can I use ipmitool in these servers (on Sun, IBM and other hardwares) to detect the power supply status?
I'd recommend you to look at FreeIPMI which is very similar for the systems and how developers claim it is easier in setup and has better portability in comparison with ipmitool. To setup power supply monitoring you can use there Powerman (http://code.google.com/p/powerman/) by adding in powerman.conf
You can look for additional options here (http://www.gnu.org/software/freeipmi/freeipmi-faq.html).
