The role of the vSphere HA cluster is:

To implement each ESXI host, when a single point of failure occurs, transfer the virtual machine resources of that host to other ESXI hosts to run. To meet this function, you must have the same network configuration (such as distributed network) and shared storage.

Implement cluster step 1, create a new cluster

2. Add and drag each ESXI host to a new cluster

About ESXI5.5. On the warning notice, the solution:

In ESXi5.0, the DataStore HeartBeat function is added, requiring at least two or more shared storage. That is to say

Das.heartbeatdsperhost to change the amount of detection signal data storage required. The valid value is 2-5, and the default is 2.

Das.ignoreinsufficienthbdatastore is used to disable the created configuration problem if the host does not have sufficient vSphere HA detection signal data storage. The default is false.

ESXi warns that there is only one DataStore:

1. Select HA- configuration-vSphere HA- Advanced option.

2. Enter das.ignoreinsufficienthbdatastore in the options window and true in the numeric window.

Note: after establishing the cluster, modify the configuration item first, and then pull the host, which takes effect faster.

3. Failure experiment steps
