OK, I've set the stonith action to "poweroff" and I already had quarum action set to "ignore". The "poweroff" makes is much easier to re-set "stonith-enabled" to "false" so that I can get two systems online again. ;-)<BR>
<BR>
However, I was more hoping to be able to reboot the fenced system without triggering a reboot (or halt) of the working system. Here are some specifics:<BR>
<BR>
SLES11 HAE (GA)<BR>
external/ipmi<BR>
two HA servers

And the relevant pair of constraints:

<FONT SIZE="2"> <rsc_location id="stonith_hikari2_on_hikari" node="hikari2" rsc="ipmi_stonith_hikari2" score="-INFINITY"/></FONT>

Any suggestions as to what needs changing so that the stonith deathmarch can be avoided?<BR>
