Enum Description
A datastore can become inaccessible due to a number of reasons as
defined in this enum InaccessibleReason.
The reason for a datastore being inaccessible is reported in
inaccessibleReason.
APD ("All Paths Down") is a condition where a SAN or NFS storage has
become inaccessible for unknown reasons. It only indicates loss of
connectivity and does not indicate storage device failure or
LUN removal (Permanent Device Loss or PDL)
A difference between APD and PDL is that APD may recover
in which case all use cases will start to work as before. In case of PDL
the failed datastore/device is unlikely to recover and hence the device
path information and data cache will be emptied. If the PDL condition
recovers, the failed datastores have to be added back to the host. Once
in PDL a datastore cannot be added back until there are no longer any
open files on the datastore.
PDL is not linked to the APD and can happen at any time with or without APD
preceding. If APD and PDL occur at the same time, APD will be reported first.
Once (and if) the APD condition clears, PermanentDataLoss will be reported if
PDL condition still exists.
