VASA – Error while removing an entry for the provider in the providerCache

Some time ago, I hooked our Virtual Volume (VVol) capable storage array up to a vSphere 6.5 cluster. I did a few preliminary tests, such as adding the VASA (vSphere APIs for Storage Awareness) Provider, creating the VVol datastore, observing the creation of the Protocol Endpoints (PEs), and of course creating some virtual machines as […]

One of the hosts in our four node cluster hit an issue, which meant that the storage on that host was no longer available to the VSAN datastore.
