High availability - host failure number

[fred974]

Hi,

I have enabled HA in my pool of 4x host running xe pool-ha-enable heartbeat-sr-uuids=<UUID>.

QUESTION: Do I also need to set the maximum host failure number? As I have 4x hosts, am I correct to think that I will need to set it to 3?

[09:31 uk ~]# xe pool-ha-compute-max-host-failures-to-tolerate
4

Do I simply leave everything as is or do I manually set the value to 3 with xe pool-param-set ha-host-failures-to-tolerate=**3** uuid=<Pool_UUID>

Thank you
