If an X mark is added to the end of the device ID (00:00:3C X, for example), the LDEV that
the number indicates is a Thin Provisioning virtual volume. For details on virtual volumes, see
the HP StorageWorks XP24000/XP20000 Thin Provisioning Software User's Guide.
•
P-VOL Fence Level: Select the fence level for the new pair(s). The fence level determines the
conditions under which the MCU will reject write operations to the P-VOL. Never is automatically
set for an asynchronous pair. See
for further information on this
option.
◦
Never: The P-VOL will never be fenced.
◦
Data: The P-VOL will be fenced when the MCU cannot successfully execute an update
copy operation for any reason.
◦
Status: The P-VOL will be fenced only if the MCU is not able to change the S-VOL status
to suspended when an update copy operation fails.
•
Asynchronous Parameters (async only):
Error Level: Error level for the new pair(s): Group or LU.
•
The Cancel button cancels the settings you have made and closes the Change Pair Option
dialog box. The Set button sets the parameters and closes the Change Pair Option dialog box.
To set the parameters on multiple volumes at once without changing individual parameters per
volume, make the box for parameters that you do not want to change blank. Only the parameters
that you input will be changed.
To change the fence level or error level pair option for one or more XP Continuous Access pairs:
1.
Connect to the MCU of the pair(s) for which you want to change the pair option, and open
the XP Continuous Access main window.
2.
In the tree, select a port, host group, desired CU, or upper CU grouping.
3.
In the list, select the pair(s) for which you want to change the pair option. When a port is
selected in the tree, the pair(s) can be selected from the current volume list.
Select either XP Continuous Access Synchronous pairs or XP Continuous Access Asynchronous
pairs (not both). Use the Display Filter as needed to display the desired pairs (for example,
select Async only)
4.
Right-click, and click Change Pair Option to open the Change Pair Option dialog box (see
“Change Pair Option Dialog Box (Synchronous and Asynchronous)” (page 129)
).
5.
On the Change Pair Option dialog box, select the desired pair option for the selected pair(s),
and click Set to close the Change Pair Option dialog box. The preview list displays the
requested change pair option operation(s).
6.
Verify the requested operation(s) in the preview list.
To change one or more operations, select the operation(s) from the preview list, right-click,
and click Modify. To remove one or more operations, select the operation(s), right-click, and
click Delete. To cancel all operations, select all the operations in the preview list, right-click,
and click the Delete command, or click the Cancel button.
7.
To perform the change pair option, click the Apply button.
If one or more operation(s) did not start normally, the preview list displays only the operation(s)
that did not start normally. An error code is displayed in the Error Code column in the preview
list. To display an error message, select one LU, right-click, and click Error Detail. After you
see an error message, click OK to close the error message.
8.
On the Pair Operation window, verify that the change pair option operation(s) completed
successfully.
If an error occurs, you can display the error message by right-clicking on the operation and
clicking the Error Detail command.
