2. Select a mirror ID (0 to 3) from the Mirror ID list.
3. Select a restore journal from the R-JNL list. Only journal numbers between 000 and 0FF
display.
NOTE: The M-JNL list does not display journal numbers used by Continuous Access Journal
Z.
7. From the CT Group list, specify the consistency group number. If possible, assign the consistency
group number matching the Continuous Access Journal journal number (best practice).
8. In the DKC list, select the secondary system, which must be the same for all pairs created in
the operation. Secondary systems are identified in the list by serial number, LDKC number,
controller ID, model name, and ID (Path Gr. ID).
When the system is not connected to a P9500, only 0 (default) is available for Path Gr. ID.
If a pair is already created in the mirror being used, you must select the same secondary
system as the existing pair.
9. In the Initial Copy list, select one of the following:
• Entire, to create the Cnt Ac-J pair relationship and copy the data from primary to secondary
volumes immediately.
• None, to create the Cnt Ac-J pair relationship but copy no data from primary to secondary
volumes. If you select this option, the data in the P-VOL and S-VOL must be identical.
• Delta, to create the Cnt Ac-J pair for a delta resync. The initial copy operation does not
start and the pair status changes to HOLD or HOLDING.
10. In the Priority list, specify the scheduling order for this initial copy operation, if the number of
initial copies in the operation is greater than the maximum concurrent copy setting. 1 to 256
can be specified, 32 is the default.
See “Maximum initial copy operations and priorities” (page 24) if running more initial copies
than previously specified.
If a time-out error occurs during the Paircreate operation, the copy operation might not have
been executed in the order that you 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 Paircreate operation.
11. In the Error Level list, select one of the following options for the action to take if a failure occurs
during this operation:
• Mirror, to split all pairs in the failed pair’s mirror. Mirror is the default.
• LU, to split only the pair that failed.
12. Click Set to close the Paircreate dialog box.
13. In the Preview list check your settings.
• To modify a setting, right click and select Modify.
NOTE: If you right click more than one volume in the Preview list and select Modify,
the Select Other S-VOL(s) list in the Paircreate dialog box indicates No Change. To change
the setting, select another option from the list.
• To cancel a setting, right click and select Cancel.
14. Click Apply to apply the settings and create pairs.
