What steps must be taken to make the datastore visible to ESXiA?

A new LUN has been presented to two ESXi hosts, ESXiA and ESXiB. The LUN can be seen from both servers. A new VMFS volume is created on the LUN using a vSphere Client attached to ESXiB. The new datastore is visible on ESXiB. but not on ESXiA. What steps must be taken to make the datastore visible to ESXiA?
