I have a 2-host cluster with HP StoreVirtual VSA running as the storage system. I upgraded vSphere from 5.5 to 6.0. After upgrading, I had been receiving some alarms such as "Insufficient resources to satisfy vSphere HA failover on cluster" and "Insufficient vSphere HA failover resources", I then proceeded to disable HA on the cluster. Once doing this, I then receive an issue of "All shared datastores failed on the host x.x.x.x" on one of the hosts.
I believe the HA alarms are being generated because of some problem happening related to the datastores, but I have not been able to resolve this. There does not seem to be any issues related to the shared datastores. The 2 shared datastores are connected and appear to be fully functional. I've created this discussion under HA & FT as I believe this be related. If anyone would have any feedback to share on this, I will be appreciative of any assistance.
Thank you!
