HA error on one of the hosts in ESX4 cluster. Internal AAM error???
I have decided to turn HA availability on our ESX4 3 host cluster.
All Hosts are running ESX 4.0.0 294855 and all are identical hardware with same amount of CPU, memory etc.
The first 2 hosts successfully are now part of the HA but the 3rd host attempts to configure HA and then comes up with an error:
"cmd addnode failed for primary node: internal AAM error - agent could not start: unknown HA error"
It seems like it has to install a HA agent on each host but for some reason it doesnt want to install on the last host.
Does anyone know why I might be getting this error. Only today did we patch this host up to be the same version as the rest. I have been doing this gradually over the last few days.
Any assistance would be greatly appreciated.
