6.
Click Set to close the Paircreate pane and set parameters.
The list changes to the Pair Settings Parameter list (Paircreate). The Pair Settings Parameter list
(Paircreate) is updated by parameter settings and displays all pairs being created. Initial copy
options and pair options selected are applied to all pairs, but you can modify options for
each pair individually as needed (see
“Modifying parameters and deleting LUs” (page 96)
).
7.
From the Pair Settings Parameter list (Paircreate), check the RCU S/N and SSID, S-VOL, and
copy options for each pair. You can modify options as needed (see
). Ensure that all XP Continuous Access options for each new pair
are correct.
8.
To execute the paircreate requests quickly, select the Use Time-Saving Mode check box above
the Pair Settings Parameter list (Paircreate).
9.
Click Apply on the XP Continuous Access main pane to create (start) specified XP Continuous
Access pairs. The MCU starts initial copy operations according to the initial copy priority and
maximum initial copy activities setting of the RCU.
10. In the XP Continuous Access main pane, verify that new XP Continuous Access pairs are
displayed correctly (COPY status) in the Volume list. To monitor the status of new pairs, click
Refresh to update information in the Volume list, or use the Pairdisplay pane (see
XP Continuous Access pair status for LUs and LDEVs (Pairdisplay)” (page 96)
) to monitor
detailed status of each pair.
The Paircreate operation is rejected if the P-VOL is in the correction access or correction copy
state. If this occurs, wait for the volume state to change and repeat this procedure. If the status
is not displayed correctly, ensure that the correct CU image is selected.
CAUTION:
If a timeout error occurs when the Use Time-Saving Mode option is selected, access
the XP Continuous Access main pane, and confirm the volumes on which the paircreate operation
could not be performed. Deselect the Use Time-Saving Mode option for failed volumes, and retry
the paircreate operation.
After the Paircreate pane closes, the list changes to the Pair Settings Parameter list (Paircreate).

•
Port, Group, and LUN of the LU in the connected disk array.
•
S/N and SSID of the RCU (MCU if you are connected to the RCU).
•
Port, Group, and LUN of the LU to be the S-VOL.
•
Type: Synchronous or Asynchronous of the pair created.
•
Mode: Entire: Copy all cylinders. No Copy: Do not copy.
•
Fence: Conditions under which the MCU rejects write operations to the P-VOL: Never, Data,
or Status.
•
Pace: Number of tracks (1-15) for initial copy.
•
Priority: Priority (scheduling order) of initial copy operations.
•
Diff: In the measurement of the Cylinder or the Track, XP Continuous Access manages
differentials among data.
