Questions HA

[edgee]

Hi all!!

I have configured 2 ESX server 3.5. Then I have a virtual machine with Virtual Center 2.5. I have created my cluster and then I have configurated HA. Everything worked fine but suddenly my two hosts become "disconnected" and virtual center hangs. If i connect directly to one ESX all machines are running and Host looks like fine. 5 minutes later the situation starts again. I think there is no communication problem, event viewer does not show any error.

The most important erorrs are the following:

"The host is reporting error in it's attemps to provide HA support"

I have tried to reconfigure HA ad works fine jus fr a while, then the hosts become again disconnected.

Any ideas??

Thanks!

try removing the hosts from the cluster, destroy the current cluster, create a new cluster, move your hosts back into the new cluster and enable HA again.

Ok, tomorrow I will try this !

Another error is the following:2

"Insufficient resources to satisfy configured failover level for HA", I have 16 GB available on each node and I have only one virtual machine with 2 gb of memory assigned.

Should resolve the problem destorying my cluster and making a new one?

Thanks again

This has to do with the quantity of hosts that you have in the cluster, and the number of host failures allowed. If you have only 2 hosts, that number can't be larger than 1. Are both the hosts' HA working properly? Try and right click on the cluster, and choose "reconfigure for HA"

I also normally use the setting: Allow to power up even if VM violates availability contraints,

Most of the memory I have assigned to VMs isnt fully utilized anyway, I dont want my VMs staying powered off after a host failure because VC thinks there isnt enough resource in the cluster,
