NOTE:

When creating more than one pair at a time, make sure that the S-VOLs to be assigned automatically

are available. If an S-VOL is not available, you will have to select the S-VOL individually.

Select Other S-VOL(s): Specify how URz automatically will assign secondary data volumes if two

or more primary data volumes are selected in the Pair Operation window.
• Increment: URz increments volume numbers of the resulting secondary data volumes one by

one. For example, if the volume numbers of the three primary data volumes are 01, 02, and

03, the volume numbers of the resulting secondary data volumes will be 11, 12, and 13 if you

select the volume number 11 with the S-VOL drop-down list.

• Input Next: URz users can specify a volume number for each primary data volume. For

example, if two primary data volumes are selected, the URz user must select Input Next,

specify the secondary data volume for the first primary data volume with S-VOL, and then

click Set. Next, the user must specify the secondary data volume for the second primary

data volume with S-VOL, and then click Set.

• Relative to P-VOL: URz calculates the difference between volume numbers of two adjacent

primary data volumes, and then determines volume numbers of secondary data volumes.
For example, if the volume numbers of the three primary data volumes are 01, 05, and 06, the

volume numbers of the resulting secondary data volumes will be 02, 06, and 07 if you select the

volume number 02 with the S-VOL drop-down list.

NOTE:

If you select and right-click more than one volume in the Preview list and then select Modify, the Add

Pair window appears and the Select Other S-VOL(s) drop-down list displays No Change. If you want

to change the setting with this drop-down list, select another item from the drop-down list.

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 (i.e., 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
