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 show journal group numbers used by Universal Replicator for Mainframe.

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 show journal group numbers used by Universal Replicator for Mainframe.

CT Group: Specify a consistency group. This option cannot be changed after a pair has been
created.

DKC: Select the serial number with the number of LDKC and the controller ID with the model
name 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: Specify whether to start the initial copy operation after the volume pair is created.
The default is Entire.

Entire: The initial copy operation starts after the volume pair is created. When the initial
copy operation executes, all data on the primary data volume is copied to the secondary
data volume.

None: The initial copy operation does not start after the volume pair is created. The
primary storage system starts copying of update data as needed. Ensure that the primary
data volume and secondary data volume are already identical when using None.

Delta: No initial copy operation starts after the volume pair is created. The status of the volume
pair changes to HOLD or HOLDING, which means that the pair is ready for the delta resync
operation.

Priority: Specify priority (scheduling order) of the initial copy operations (1-256). The default
setting is 32.

If the timeout error occurs during the paircreate operation, the copy operation may not be
executed correctly in the order that you have set with the Priority parameter. The timeout 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 paircreate operation.

Error Level: 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 consistency group where the pair
belongs are split.

LU: If a failure occurs with a pair, only the pair are split.

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:

(1) The number of mirrors registered in the master journal

(2) The number of mirrors to be added by the Paircreate window

(3) The number of mirrors for volumes in the Preview list in the Pair Operation window

Set: Applies the settings to the Preview list in the Pair Operation window (

“Pair Operation

Window” (page 122)

).

Cancel: Discards the settings and closes the window.
