A vSphere operator finds this error message: Device or filesystem with identifier [naa.6000eb31dffdc33a000000000000002a] has entered the All Paths Down state. What should the operator conclude from th

An APD state refers to a storage device, not a host, so the host is not necessarily inaccessible.

An APD state refers to a storage device, not a host, and automated recovery of VMs is not directly related to the APD state of the storage.

The 'All Paths Down' (APD) state indicates that an ESXi host has lost all connectivity to a storage device identified by its NAA ID. When a device enters the APD state, it means that the ESXi host no longer detects any active paths to that storage device, implying a permanent or prolonged failure of the storage or its connectivity, making recovery uncertain or unlikely without manual intervention.

The 'All Paths Down' state implies that all known paths to the device are gone and the device is considered failed or permanently unavailable, rather than temporarily inaccessible and expected to become available.
