A new LUN has been provisioned to all hosts in a vSphere 5.x cluster. On one host a new VMFS
datastore has been created.
How will the new datastore be discovered by the other ESXi 5.x hosts?

A.
A rescan of all host bus adapters is periodically performed by ESXi hosts to detect new VMFS
datastores.

B.
New VMFS volumes are automatically added to members of a cluster by vCenter 5.

C.
A manual refresh is required on each ESXi 5.x hosts to discover new VMFS datastores.

D.
A refresh of all host bus adapters is periodically performed by ESXi hosts to detect new VMFS
datastores.

Explanation:

You need to manually refresh every ESXi 5.x host to get it to discover newly added VMFS
datastores.
