The following error displays during the final step of the configuration for a VMware High Availability (HA) cluster attached to five datastores:
The number of heartbeat datastores for host is 0, which is less than required.
What condition would cause this error?
A. One of the hosts in the cluster is not attached to the datastores planned for use with HA.
B. The hosts in the cluster do not have Storage DRS configured on one or more of their datastores.
C. One of the hosts in the cluster has an invalid Storage Policy configured on one or more of their datastores.
D. The hosts in the cluster contain one or more datastores configured with a 1 MB block size.
Correct Answer: A
Explanation/Reference:
Explanation:
A: When vSphere HA is enabled the vSphere HA master host sends heartbeat messages to the slave hosts. Thus if the heartbeat for a host is 0 then it is because that host, even though part of the cluster, is not attached to the datastore.
Incorrect Answers:
B: Storage DRS is used to make correct placement decisions for workload balancing and is not indicated by a heartbeat of 0.
C: Having an invalid storage policy will not result in a heartbeat datastores setting of 0.
D: The block size of the hosts in the HA cluster is not indicative of the heartbeat datastores setting of 0.
