This option is used to enable Delta Resync with no host
update I/O by copying only differential JNL instead of
copying all data.
The HUR Differential Resync configuration is required.
Mode 506 = ON:
Without update I/O: Delta Resync is enabled.
With update I/O: Delta Resync is enabled.
Mode 506 = OFF (default):
Without update I/O: Total data copy of Delta Resync is
performed.
With update I/O: Delta Resync is enabled.
Note:
Even when mode 506 is set to ON, the Delta Resync may
fail and only the total data copy of the Delta Resync
function is allowed if the necessary journal data does not
exist on the primary subsystem used for the Delta Resync
operation.

- C/T displays the value of when JNL copy is completed.
Mode 530 = OFF (default):
C/T displays the value of when JNL restore is completed.
Note:
At the time of Purge suspend or RCU failure suspend, the
C/T of Universal Replicator for Mainframe displayed by
Business Continuity Manager or Storage Navigator may
show earlier time than the time showed when the pair was
in the Duplex state.
