I m using RHCS, and one of the important part is to have fencing working for my environment. Normally using a physical server, i can simply used the ILO as my fence device. However as guest machine inside esxi, sending reboot instruction via ILO fencing, will actually reboot the host/physical machine.

Is there anyway in vsphere/esxi management part that i can assign ILO to a specific vm guest machine, so that fencing will only affected a single vm guest.

I m using the latest vmware vsphere hypervisor.

or is there any other choice of fencing and reliable ?

  • The iLO will not be aware of the guests, it sounds to me like you need to talk to the APIs of the Hypervisor. – SpacemanSpiff Apr 18 '11 at 2:11
  • thanks spacemanSpiff, i think the only way is by developing my own fence agent using vi toolkit or via hypervisor soap interface. – abi aqil Apr 18 '11 at 3:33

I did a quick google for "RHCS vsphere fence agent" and found this link, which references a third-part script that sounds like it does what you want.

I have no idea if it'll help, I just mashed some keys at google because your problem sounded interesting :)


You need to use fence_vmware_soap which is available in RHCS or CentOS 6.2 or later.


There's no way to do this. Why don't you explain better what you're actually trying to achieve and we may be able to help you.

  • I don't know why this got downvoted, it can't be done, that's the answer. I did try offer to help the user if they came back to me with extra details. – Chopper3 Jul 20 '11 at 13:47
