In a vSphere High Availability (vSphere HA) cluster, which condition can be detected by datastore heartbeating?
In a vSphere High Availability (vSphere HA) cluster, datastore heartbeating is used to detect network isolation. When a host is network isolated, it cannot communicate with the master host over the management network. Datastore heartbeating allows the master host to determine if the isolated host is still operational by checking for heartbeats through the shared datastore. If heartbeats are not detected, it indicates that the host has failed, network isolation has occurred, or the host is in a network partition, allowing the master host to take necessary actions such as restarting virtual machines.
When the master host in a vSphere HA cluster can not communicate with a slave host over the management network, the master host uses datastore heartbeating to determine whether the slave host has failed, is in a network partition, or is "network isolated". If the slave host has stopped datastore heartbeating, it is considered to have failed and its virtual machines are restarted elsewhere.
B, yes
B 484/500 27-APR-2023
All-Paths-Down (APD) A datastore is shown as unavailable in the Storage view. A storage adapter indicates the Operational State of the device as Dead or Error. All paths to the device are marked as Dead. You are unable to connect directly to the ESXi host using the vSphere Client The ESXi host shows as Disconnected in vCenter Server
B is correct, you know? https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-0502B198-F5F7-4101-969C-C5B6F364C678.html#GUID-0502B198-F5F7-4101-969C-C5B6F364C678
