NOTE:
If you select and right-click more than one volume in the Preset list and select Modify, the
Paircreate pane appears, and the Select Other S-VOL(s) list displays No Change. To change the
setting with this list, select another item from the list.
• Mirror ID: Assigns a master journal group to the primary data volume, assigns a restore journal
group to the secondary data volume, and assigns a mirror ID to the volume pair.
• M-JNL: Assigns a master journal group to the primary data volume.
NOTE:
M-JNL does not display journal group numbers used by Universal Replicator for z/OS.
NOTE:
M-JNL displays only journal groups containing journal volumes belonging to the CLPR where
the selected volumes belong.
• Mirror ID: Assigns a mirror ID to the volume pair.
• R-JNL: Assigns a restore journal group to the secondary data volume.
NOTE:
R-JNL does not display journal group numbers used by Universal Replicator for z/OS.
• CT Group: Consistency group.
NOTE:
You cannot change his option after a pair is created.
• DKC: Secondary array's serial number and controller ID. You can also specify the path type
(for example, channel type).
NOTE:
The secondary array must be the same for all pairs being created during one operation.
• Initial Copy: Specifies whether the initial copy operation is started after the volume pair is created.
• 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. This is the default.
• None: The initial copy operation does not start after the volume pair is created. The primary
array starts copying update data as needed.
CAUTION:
You must ensure that the primary and secondary data volumes 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, which means the pair is for contingency delta resync operations.
• Priority: Priority (scheduling order) of the initial copy operations (1-256). The default is 32.
