Examine the performance and accessibility of virtual machines to diagnose problems in the Virtual SAN cluster. Verify Drivers, Firmware, Storage I/O Controllers Against the VMware Compatibility GuideUse the Virtual SAN Health Service to verify whether your hardware components, drivers, and firmware are compatible with Virtual SAN. Examining Performance in a Virtual SAN ClusterMonitor the performance of virtual machines, hosts, and the Virtual SAN datastore to identify potential storage problems. Network Misconfiguration Status in a Virtual SAN ClusterAfter you enable Virtual SAN on a cluster, the datastore is not assembled correctly because of a detected network misconfiguration. Virtual Machine Appears as Noncompliant, Inaccessible or Orphaned in Virtual SANThe state of a virtual machine that stores data on a Virtual SAN datastore appears as noncompliant, inaccessible or orphaned because of failures in the Virtual SAN cluster. Attempt to Create a Virtual Machine on Virtual SAN FailsWhen you try to deploy a virtual machine in a Virtual SAN cluster, the operation fails with an error that the virtual machine files cannot be created. Stretched Cluster Configuration Error When Adding a HostBefore adding new hosts to a stretched cluster, all current hosts must be connected. If a current host is disconnected, the configuration of the new host is incomplete. Stretched Cluster Configuration Error When Using RVC to Add a HostIf you use the RVC tool to add a new host to a stretched cluster, the configuration of the new host is incomplete. Cannot Add or Remove the Witness Host in a Stretched ClusterBefore adding or removing the witness host in a stretched cluster, all current hosts must be connected. If a current host is disconnected, you cannot add or remove the witness host. Disk Group Becomes LockedIn an encrypted Virtual SAN cluster, when communication between a host and the KMS is lost, the disk group can become locked if the host reboots.
