VMware HA Problem with Update 3

This is taken from Mr. Scott Lowe, and the VMware KB.

To fix the problem, users have two options:

   1. Disable virtual machine failure monitoring within the VMware HA cluster.
   2. Reconfigure the host to change the heartbeat delay.

To reconfigure the host to change the heartbeat delay, follow the steps below:

   1. Disconnect the host from VC (right-click on the host in the VI Client and select “Disconnect”).
   2. Login to the VMware ESX server via SSH and obtain root permissions. Remember that best practices specify not to allow root SSH login, so you’ll need to login as an ordinary user and then use “su -” to become root.
   3. Using a text editor such as nano or vi, edit the file “/etc/vmware/hostd/config.xml” and set the value of heartbeatDelayInSecs to 0, like this:
      <vmsvc>
      <heartbeatDelayInSecs>0</heartbeatDelayInSecs>
      </vmsvc>
   4. Restart the management agents on the VMware ESX server.
   5. Reconnect the host in VC (right-click on the host in the VI Client and select “Connect”).

No information is yet available on when this issue will be fixed.
