Cause:
=======
Strange behavior of some HW IPMI implementations (for example IBM x3550, brand new supermicro motherboard).
Consequence:
============
Old behavior:
perhaps (chassis power status)
chassis power off
chassis power status (wait for this to return "off")
chassis power on
chassis power status (wait for this to return "on")
and the BMC controller for some difficult to understand reason shuts itself
down after the "chassis power off", so it will be not able to power on machine.
Fix:
====
Add support for power cycle command, which doesn't shut BMC controller.
Result:
=======
Old behavior is default, so nothing change without reconfiguration. But now, there is new method option, which can have value cycle, what will cause a new behavior (use ipmi power cycle command).
Example of usage:...
<fencedevices>
<fencedevice agent="fence_ipmilan_new" ipaddr="1.2.3.4"
login="root" name="ipmifd1" passwd="password" method="cycle" />
