• Volume: Port - G-ID, LUN of the selected volume.
NOTE:
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
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:
for each volume, set the parameter values you do not want to change to blank. Only the parameters
you input are changed.
