Note: R-JNL does not display journal group numbers used by Universal
Replicator.
• DKC: Allows you to select the serial number (the LDKC number) and the
controller ID (model name that indicates the model) of the secondary
storage system. This option also allows you to specify the path type (i.e.,
channel type).
Note: The secondary storage system must be the same for all pairs being
created during one operation.
• Initial Copy: Allows you to specify whether to start the initial copy
operation after the volume pair is created. The default is Entire.
– Entire: The initial copy operation will start after the volume pair is
created. When the initial copy operation executes, all data on the
primary data volume will be copied to the secondary data volume.
– None: The initial copy operation will not start after the volume pair is
created. The primary storage system starts copying of update data as
needed.
Caution: The user must ensure that the primary data volume and
secondary data volume are already identical when using None.
– Delta: No initial copy operation will start after the volume pair is
created. The status of the volume pair will change to Hold which means
that the pair is for delta resync operation.
• Priority: Allows you to specify priority (scheduling order) of the initial copy
operations (1-256). The default setting is 32.
Note: If the time out error occurs during the Add Pair operation, the copy
operation may not be executed correctly in the order that you have set
with the Priority parameter. The time out error may be caused by the CU
configuration or a remote copy path error. Review the error, release the
pair with the error, and then retry the Add Pair operation.
• Error Level: Allows you to specify the range used for splitting a pair when
a failure occurs. The default is Group.
– Group: If a failure occurs with a pair, all pairs in the mirror where the
pair belongs will be split.
– Volume: If a failure occurs with a pair, only the pair will be split.
• CFW: Allows you to specify whether to copy cache-fast-write data to the
secondary data volume. The default is Only P-VOL.
– Only P-VOL: Does not copy cache-fast-write data to the secondary
data volume.
– Copy to S-VOL: Copies cache-fast-write data to the secondary data
volume.
• M-JNL Information: Displays information about the master journal.
– Current Mirror(s): Indicates the number of mirrors registered in the
master journal.
