About host maintenance mode options for vSAN enabled hypervisor clusters

Hypervisor cluster profiles detect the vSAN configurations on a VMware cluster and are aware of vSAN enabled clusters. Hence, whenever a host which is part of a vSAN enabled cluster is moved to maintenance mode, the host is moved to a data evacuation mode such as Ensure accessibility or Full data migration.

Following are the data evacuation mode scenarios as part of vSAN aware hypervisor cluster profile operations:

  • Ensure accessibility mode: This data evacuation mode is used when the remediate operation is performed from the vSAN aware hypervisor cluster profile.
  • Full data migration mode: This data evacuation mode is used when you:
    • shrink a cluster from the vSAN aware hypervisor cluster profile, or
    • delete a hypervisor profile, or
    • perform an OS redeploy on a hypervisor profile.
