I'm running into an unusual problem that perhaps someone may have resolved.
A couple of my ESXi 5.1 hosts do not see a datastore. However, the datastore FC LUN is mounted and active. VMs that are on this active LUN are also running. Running esxtop, I can see the device with data being written to it.
I've run a rescan all/vmfs a few times but I keep on see the following error:

So far, the VMs and the hosts seem to be stable. Has anyone run into the same issue?
