DBCS double byte character set
Delta Resync A method used in a 3DC Multi-Target configuration to synchronize a predefined delta resync
pair (a UR pair consisting of a local site volume and a remote site volume) by copying only the
differences between the volumes in the pair.
Delta Resync pair A UR copy pair for performing Delta Resync. This copy pair is either in HOLD, HOLDTRNS,
HOLDER, or NODELTA status.
device address A unique number assigned to each device in the LCU. When combined with the LCU number,
provides a unique identifier for a volume in the storage system. Also known as the unit number

This function disconnects the primary site copy pair from the secondary site copy pair and tests
the secondary site to determine if the DR configuration is operating normally. When the test ends,
you must resynchronize the primary site with the secondary site.
DISPLAY command An operator command used to display the status of BCM Monitor. You can specify this command
in the MODIFY command to display the current valid value of the parameter in the YKMONOPT
