It's in band isn't it? I experienced performance problems when checking against Dell PERC cards(megaraid firmware) with MegaCLI -LdPdInfo and MegaCLI -PDList, the io_wait queue was thrashed as reported by iostat resulting many slow queries on the MySQL host. Looks like hardware problems(including disk failure) are detected by IPMI hardware, namely BMC. I considered monitoring hardware events out band, and implemented as nagios passive checks on IPMI nodes. I also wrote a simple tutorial at http://svn.savannah.gnu.org/viewvc/trunk/contrib/pet/README?root=freeipmi&view=markup, and the passive check is discussed in section 2.2 NAGIOS INTEGRATION; there is also example configuration at http://svn.savannah.gnu.org/viewvc/trunk/contrib/pet/ipminodes.cfg?root=freeipmi&view=markup. It requires FreeIPMI-1.1.1 on the receiver host though, which will be released shortly in one or two weeks. How do you think about it?
