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