Hello,
Following local experience with ipmi stonith, we've found that certain systems (i.e. Sun X4200)would occasionally fail to perform a reset. Using a power off and then a power on proved far more reliable. So if scripts are likely to find their way into mixed environments then going the route of the lowest common denominator is probably the best / safest way to go ? NB. The script we use has been previously submitted to this list. Cautionary footnote. For more recent server systems that claim ipmi compatibility it appears that the support for ipmi is at the kernel level only (and not via the ilo itself...) so if the system becomes unresponsive and a fencing action is sent, it probably won't have any effect... For these systems we've resorted to using non-ipmi based scripts (i.e. modified rilo etc). ipmi is a useful standard, but as with any standard it helps end users (us) if manufacturers implemented things in a consistent manner :-).
