While trying to Unmount a datastore I am getting following warning. The Datastore Heartbeating settings of the Cluster is having following option checked - "Select any of the cluster datastores taking into account my preference" with no datastore selected.

Shall I proceed with unmounting that datastore? Please help me to Unmount the datastore properly.

Completely normal if the datastore is bsing used for VMware HA.

Safe to proceed, but you may want to check how many datastores you have being used as a VMware HA heartbeat, this can be changed in HA Cluster settings.

By default 2 datastores are used for VMware HA Datastores.

Thank you for your quick reply. I have few queries. I will very helpful for me if you clear my concerns.

1. Why is this datastore giving warning while the Datastore Heartbeating settings of the Cluster having following option checked - "Select any of the cluster datastores taking into account my preference" with no datastore selected.


2. As per the warning if I proceed with Unmounting it will restart any powered-on VM on the host. Will this happen? Can you please confirm.

3.  How do I confirm whether the cluster is using 2 datastores or not for HA purpose?

4. The datastore is having hearbeat files. Will there be any problem if I proceed?

configure at least two datastores you want to use. (not the one you want to dismount)

2. As per the warning if I proceed with Unmounting it will restart any powered-on VM on the host. Will this happen? Can you please confirm.

no. VMware HA, restarts VMs, when a Host fails. FDM agent uses a combination of networking and datastore heartbeats to determine if a host has failed.

3.  How do I confirm whether the cluster is using 2 datastores or not for HA purpose?

check configuration.


4. The datastore is having hearbeat files. Will there be any problem if I proceed?

reconfigure to use a different datastore.
