This article helps determine which hosts are compatible for protected HA virtual machines using the prettyPrint.sh script.
This article can also be used to proactively show compatibility, or show when a failover occurred after the event.
Note: VMware recommends gathering all FDM files as soon as possible after a failure. Performing any actions (such as removing a host, reconfiguring VMware HA Cluster, or unregistering/registering a virtual machine) complicates log analysis and root cause analysis.
For information about collecting diagnostic information, see:
Symptoms:
- An unexpected failover occurs in a VMware HA cluster and certain virtual machines do not failover.
- vSphere HA cluster experiences a host failure or a host isolation and one or more virtual machines has failed to failover.
- One or more virtual machines do not successfully failover.
