Virtual Center shutdowns all VMs in HA cluster

[AlexOsh]

Hello.

I have a question about vCenter machine. We deployed

vmware ESX 4.0 HA cluster on 3 IBM blade servers. The vCenter machine resides

on a VM on the same cluster. When we tried to reload a physical switch (in the

IBM blade center), all our VMs on the cluster were powered off automatically.

If the vCenter VM is powered off, then everything is fine - the reload of the

switch doesn't power the VMs off (and the net is ok - all machines start

working through another switch in the IBM bladecenter). If the vCenter machine

powers on (manually), all other machines, which were powered off, are powered

on too (automatically, obviously, with the help of the vCenter machine). How

can I tune the vCenter machine, so it could not power the machines on/off by

itself automatically?

ESX 4.0 (162856)

Hi,

Right click your cluster, edit settings. Select "Virtual Machine Options" under "Vmware HA" and choose the host isolation response you want for the entire cluster and/or individual VM's. If you don't have redundant network connections between your ESX machines you probably want to leave the VM's powered on for when you need to do network maintenance or your switch dies. You should probably also disable HA while doing maintenance. You should consider building some network redundancy if this is a production environment.

Hope it helps!
