Ok. Thanks for clarifying this
You can test fence_ilo2 from command line (if you try a reboot from
command line I suggest to set the host into maintenance mode in oVirt as
otherwise oVirt tries to fence the host too and ILO/IPMI interfaces
sometimes show strange behavior when resetting it twice):
# /usr/sbin/fence_ilo2 --help
These same blades was configured in the past with RHCS and RHEL 5.x
I've already used fence_ilo2, fence_drac5 and fence_ipmilan in both
RHEL/CentOS 5.x and 6.y
I remember in the past the logic changed regarding fencing
So sometimes there was this workflow depending on agent and its
actions' support:
poweroff
status
poweron
And sometimes there were problems in timing responses so that the node
remained in power off state.
I also opened a bug for this with an improved suggestion, I don't
remeber right now some years ago for the python script
So the question is about how gui settings translates into fence_ilo2
generated command so that I can reproduce it
Thanks for the suggestion about putting host into maintenance
If ilo fencing isn't working as expected (e.g. host gets powered
off
instead of rebooted even if action is set to reboot you could try if
fence_ipmilan does the trick. You could also check if you're using the
latest BIOS version...
Eventually I'll try it.
Blades bios is the latest available as they don't receive updates any more.
For iLO2 fw I think they are on 2.x version even if the better release
probabbly was around 1.80
I'll check also this
