•
Mirror: Assigns a master journal group to the primary data volume, assigns a restore journal
group to the secondary data volume, and also assigns a mirror ID to the volume pair.
◦
M-JNL: Assigns a master journal group to the primary data volume. M-JNL does not
display journal group numbers used by Universal Replicator.
◦
Mirror ID: Assigns a mirror ID to the volume pair.
◦
R-JNL: Assigns a restore journal group to the secondary data volume.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 (that is, channel type). 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. 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.
◦
◦
Total Mirror(s): Indicates the sum of the following numbers:
(1) The number of mirrors registered in the master journal.
