Synchronization states

The RDNSYNCSTATE parameter indicates the controller's synchronization state.
Given a redundant controller pair, synchronization is the act of transferring configuration
and execution data from the primary controller to the secondary so that the secondary has
the same information as the primary when it is needed to transition into the primary role.
Synchronization is only possible for a compatible redundant controller pair; when a
compatible partner is found, the controller transitions from the 'No Partner State' to the
'Partner Visible State.' Initial-sync is the act of performing first time transfer of
synchronization data; during this time the controllers are in the 'Sync in Progress' State.
The redundant controller pair enters the 'Synchronization Maintenance State' upon
initial-sync completion. While in the Synchronization Maintenance State, the secondary

Redundancy compatibility parameter - RDNCMPT
State
Incompatible The partner's Major revision is not supported.
Incompatible The partner's Minor revision is not supported.
Incompatible Mismatched compatibility types (i.e. different platform
firmware).
Incompatible Incompatible indication for those platforms sensitive to
difference in firmware versions when firmware versions
differ and the platform does not support OPM (there are
no known examples of this platform type).
Incompatible Attempting to migrate across more than one major
release. For example, migration between R101 and
R300 is not allowed.
Incompatible Device Indexes of potential redundant partner modules
are not properly configured as consecutive odd/even
pair.
Incompatible Mismatched factory data (i.e. different platform
hardware).
Incompatible Mismatched compatibility types (i.e. different platform
firmware).
Incompatible The partner compatibility message format is undefined
or not supported.
Incompatible The partner module is executing from boot firmware
(e.g. partner is in the Alive, Ready, or Fail State). To
be compatible, both partners must be executing from
application firmware.
