When running Acropolis 4.6.1 with ESXi as the hypervisor, it is possible you will miss some storage statistics about the virtual machines, like in this screenshot.

When hovering over the column “Used storage”, a strange message appears… This message is “Data is not available because this cluster’s version is older than the current version of Prism Central.” It is even weirder, when you don’t even use Prism Central in your environment.

When you see this message, don’t panic. It is a little bug in the Prism web interface. Several customers logged a call with Nutanix support. A fix will be supplied. Today they told me, it will be in one or two months, that the date is not confirmed yet.
