You can mount a datastore you previously unmounted. You can also mount a datastore on additional hosts, so that it becomes a shared datastore.

A VMFS datastore that has been unmounted from all hosts remains in inventory, but is marked as inaccessible. You can use this task to mount the VMFS datastore to a specified host or multiple hosts.

If you have unmounted an NFS or a virtual datastore from all hosts, the datastore disappears from the inventory. To mount the NFS or virtual datastore that has been removed from the inventory, use the New Datastore wizard.

A datastore of any type that is unmounted from some hosts while being mounted on others, is shown as active in the inventory.

1

In the vSphere Web Client navigator, select vCenter Inventory Lists > Datastores

2

Right-click the datastore to mount and select one of the following options:

Mount Datastore

Mount Datastore on Additional Hosts

Whether you see one or another option depends on the type of datastore you use.

3

Select the hosts that should access the datastore.
