HP StorageWorks Continuous Access XP user guide for the XP10000/XP12000 (December 2005)

102 Continuous Access XP for the XP10000/XP12000
• Range: Range for deleting the asynchronous pair: Group, LU, or C/T.
Changing pair options (Change Pair Option)
Use the Change Pair Option command to change pair options, Fence level and Error level (asynchronous
pairs only). When the Change Pair Option command is selected, the Change Pair Option pane appears.
From the Change Pair Option pane, change pair options.

• Volume: Port - Host group - LUN of the selected volume.
NOTE: If # is added to the end of the LDEV number, such as 00:3C#, the LDEV is an external
volume. For details about external volumes, see the HP StorageWorks External Storage XP User
Guide.
• P-VOL Fence Level: Select the fence level for the new pairs. The fence level determines the conditions
under which the MCU rejects write operations to the P VOL. Never is automatically set for an
asynchronous pair. See ”Considering the P-VOL fence-level setting” on page 106 for more information
about this option.
• Never: P-VOL is never fenced.
• Data: P-VOL is fenced when the MCU cannot successfully execute an update copy operation for any
reason.
• Status: P-VOL is fenced only if the MCU cannot change the S-VOL status to suspended when an
update copy operation fails.
• Asynchronous Parameters (async only):
• Error Level: Error level for the new pairs: Group or LU.
NOTE: To set parameters on multiple volumes at one time without changing individual parameters
for each volume, set the parameter values you do not want to change to blank. Only the parameters
you input are changed.
• Cancel button: Cancels settings made and closes the Change Pair Option panel.
• Set button: Sets parameters and closes the Change Pair Option panel.
1. Connect to the MCU or RCU of the pairs to be changed, and start Continuous Access XP.
2. From the CU Number/Port Number tree on the Continuous Access XP main pane, click the number of
the correct CU image.
3. From the Volume list, click the Continuous Access XP volume pairs to be modified. Select either
Continuous Access XP Sync or Async pairs, but not both.
4. Right-click, and click Change Pair Option. The Change Pair Option pane appears.
5. Click the pair options for selected pairs, and click Set to close the Change Pair Option pane and set
parameters. The list changes to the Pair Settings Parameter list (Change Pair Option). Repeat this step
as needed to change pair options for pairs.
