Re: [Linux-cluster] need help - Fencing problem



Hello Sir,

 1st and 2nd option passed successfully.
i also try to run command with ilo's name and it run successfully so there is no issue of DNS.

i ) when i try to run fence_node command i get the following error:

[root node1 ~]# fence_node node2.drctmb.com
agent "fence_ilo" reports: Unable to connect/login to fencing device

ii) when i try to fence through Luci i get following error:

Sep 10 11:13:10 tmb luci[24270]: Unable to retrieve batch 1700106142 status from node2.drctmb.com:11111: fence_node failed:

Please let me know if there is any other why for troubleshoot

Thank you.

Regards,
Girishkumar

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.

-Ben
