Remove datastore from datastore cluster

[darmstrongnavig]

I am attempting to unmount a datastore that is part of a datastore cluster.  Needless to say, the system does not just want to let it go without making me jump through a bunch of hoops first.  Can someone point me towards some documentation that outlines the steps I need to go through?

No virtual machine resides on the datastore - This is good, there are not any VMs on the datastore

The datastore is not part of a datastore cluster - I want to remove it from the cluster.  How do I do that?

The datatstore is not managed by storage DRS - I figured this out.  I temporarily disabled Storage DRS on the cluster.

Storage I/O control is disabled for this datastore - How do I do this?

The datastore is not used for vSphere HA heartbeat - How do I disable / suspend heartbeat?

Thanks in advance.

You can remove the datastore from the cluster by dragging it into your datacenter via the vSphere client.

You can disable SIOC via a host in the configuration tab -> storage.

You can disable HA heartbeat by disabling HA on your Hosts cluster. Usually when you get this warning it means the datastore is still in use by something. First try the first 2 options and then try removing it before disabling HA on your cluster.

This should resolve the issue on removing it.

Drag and drop got the job done.

Thank you!
