Fencing with IPMI Sunfire

[janzun]

Hi,

Im trying to configure fencing with ipmi in Sunfire x2200, but it has only the 'power off/cycle' avility, nor 'power up', it puts the mng interface off and its not possible to up de server.

Is it enough for safe fencing/HA?

Hi,
I think it'll be ok.
fencing a node is powering it off , to be sure they are no write to the shared storage.

Ok, it works but it needs a special configuration:

Sunfire 2200 cant power up through ipmi, but 'fencing_ipmilan' exec a on-off command by default when it received a 'reboot' signal, so server goes down forever. You need to change the method to 'cycle':

* cli:

# fence_ipmilan -a 1.2.3.4 -l user -p pass -o reboot -M cycle

* cluster.conf:

<fencedevice agent="fence_ipmilan" name="janzun" lanplus="1" ipaddr="1.2.3.4" login="user" passwd="pass" method="cycle" power_wait="5"/>

Now it works
