Hello Mr. Anoop,
I have already try with different host & ilo name but am getting same getting

troubleshoot.
Thank you.

Hi
It seems you are using hostname of cluster nodes at the place of
hostname of ilo (ILO should have separate ip and hostname in DNS)
In below config is node1.drctmb.com assigned as hostname of node or the
hostname of ILO device? It should be hostname of ilo device..
<fencedevices>
> <fencedevice agent="fence_ilo" hostname="node1.drctmb.com"
> login="root" name="NODE1" passwd="redhat123"/>
> <fencedevice agent="fence_ilo" hostname="node2.drctmb.com"
> login="root" name="NODE2" passwd="redhat123"/>
> </fencedevices>
Thanks
Anoop

Hi,
the only reason was that when I used as shared the speed of this device
was
very very low. Marked it as non-shared it works fine. I don?t know the
reason. It was a try-error test,

For what it is worth, our experiences with HP iLO management cards:
iLO found on G1 servers does not need to be licensed, AFAIK, it does not
have the option to do so anyways.
iLO2 found on G2 and beyond does not need to be licensed either, if you
are only using it as a fencing device. We licensed all of ours, because
it enabled useful KVM with remote media capabilities that are superior
than our Raritan KVM infrastructure.
Both management cards should have their firmware updated -- they were
both problematic to us as factory-shipped, but applying their update
packs allowed them to work as advertised.
Also, can't you add "-v" for verbose output and also something like "-D
/tmp/fence.out" to save debugging info to an output file? It might help
some to see where exactly the failure is occuring. Good luck.

Subject: [Linux-cluster] need help - Fencing problem
Hello Everybody,
i am having problem of fencing a cluster node let me explain indetail :
I have installed RHEL 5.4 on HP Prolaint DL280 G5 servers and iLO 2as
fencing device. Am managing cluster through Luci - (Conga). itseems
everything is working fine. I can reboot cluster nodes through Luci and
service get transfer to another node. After rebooting node connect to
cluster automatically without any error.
Problem is i can not do Fence this node through Luci, when i try to
fence any node i get following error :
Sep 8 14:51:16 node2 fence_node[9106]: agent "fence_ilo" reports:
Unable to connect/login to fencing device
Sep 8 14:51:16 node2 fence_node[9106]: Fence of "node1.drctmb.com" was
unsuccessful
my iLO license is : iLO 2 Advanced Evaluation
Do i need to have license of iLO or there is problem in configuration
of cluster ?
how i can check cluster log in details.
Appreciate your help.
Thank you in advance.
Regards,
Girishkumar R Prajapati

2.) What version of PSP you have installed??
3.) If nothing works, I recommend using fence_ipmi

Judging from:
"Sep 8 14:51:16 node2 fence_node[9106]: agent "fence_ilo" reports:
Unable to connect/login to fencing device"
Chances are you are not using the correct username/password/IP or the
ilo is not configured for telnet logins. Try the following:
1. Login to the ilo via telnet from the command line. Be sure to use
the username/password/IP you have in cluster.conf.
2. If that is successful try:
# fence_ilo -v -a "Ilo IP from cluster.conf" -l "Ilo user from
cluster.conf" -p "Ilo passwd from cluster.conf" -o status
The -v will display exactly what the fence agent sees and is very useful
for debugging failing fences. If the status fails send me the output.
3. If the fence_ilo successful try:
# fence_node <node name from cluster.conf>
If all 3 are successful then fencing is setup properly and there may be
a problem running it from Luci, if any of the 3 fail post the error back
to the list and I'll look at it.
