When trying to add a host to a cluster this error is encountered at validation time -
"Cluster primary datastore is not valid. Cause Unable to find datastore with name xxxxxx for the cluster xxxx"
VCF 5.X
The primary datastore name has changed.
A new primary datastore is being used in the environment - this change has not been reflected in the SDDC Manager database.
Please contact Broadcom Support to assist with implementing the resolution.
