[Linux-cluster] help reqd. - VMware ESX 3.5 fencing

Wed Feb 20 15:37:56 UTC 2008

the script i sent to you was, or it should have been this one, apologies if I miscopied, as I tried lots of scripts when I was searching for the good one at the time. 

it uses the VMware::VIM2Runtime wich is the ESX 3.xx perl library

#!/usr/bin/perl

Hi,

I am facing some issues on trying to fence a node using "fence_vmware" Perl script. This script is attached in this mail.

I have a single standalone physical machine installed with VMware ESX 3.5. On top of this I have created 2 VMs with guest OS as Rhel5.1 AP. In both the VMs I have installed VMware Perl APIs. I have kept "fence_vmware" script at /sbin directory on both the VMs. My cluster.conf file is also attached in this mail. I have not configured any service becoz I want only to test VMware fencing agent here.

Through conga on trying to fence a node, I am getting following errors in my /var/log/messages.

Feb 18 21:12:24 p2pv6 fence_node[5723]: agent "fence_vmware" reports: Global symbol "$RELEASE_VERSION" requires explicit package name at /sbin/fence_vmware line 102.

Feb 18 21:12:24 p2pv6 fence_node[5723]: Fence of "p2pv5.tr.unisys.com" was unsuccessful

My initial guess is this fencing agent script can only be run with old VMware Perl APIs. Please correct me. Is there any way to run this script in my current environment?

If anyone is having a working script for VMware ESX 3.5 server, please pass it.

Thanks,

Santosh

VC is the virtual center server, i understood from your mail that you're using virtual infrastructure, but you question points out the fact that you maybe are using standalone ESX server ?

in our configuration we use an ESX farm of 4 servers managed by the VC server where we connect with the VI client

<fencedevice name="your_fence_method" agent="fence_vi3" ipaddr="yourserver_ip" port="your_vm_name" login="xxx" passwd="yyyyy"/>

though I don't know if it works on standalone server, maybe you would have ton install the VMI perlmodules described inside the script to you ESX 3.5 server

Thanks Marry for the script. I will test and let you know. By the way what's this VC server? Is it the system where I am running my VI client?

Can you please elaborate little more on this configuration like where I will keep this script, what will I mention in my cluster.conf file and etc.

Thanks,

Santosh

hello,

i'm using this script for VI 3 and  ESX3.02 i guess it would work for you too, cannot remember where I found it though :-)

note that you have to send the restart request to your VC server and not to the ESX server

Hi,

Does anybody have configured fencing in VMware ESX 3.5 environment? I appreciate any help.

I have got some info from http://www.tournament.org.il/run/index.php?/archives/140-VMware-Fencing-in-RedHat-Cluster-5-RHCS5.html .

This script given here is for VMware server. Any idea whether it will work for ESX 3.5 server or not?

My system configurations are as follows.

Host machine    : Unisys ES7000-one with host OS as VMware ESX 3.5

Guest Machines: Guest OS as Rhel5.1 AP

I am connecting to host machine using VMware VI 3.0.

Thanks,

Santosh
