• Volume: Port - G-ID - 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
• S-VOL Write: Default is Disable.
• Enable: The S-VOL of this Continuous Access XP pair is available to receive read and write
I/Os while the Continuous Access XP pair is split. If you select Enable and you want to
resync the pair later, select S-VOL in the Suspend Kind option to ensure that P-VOL and S-VOL
bitmaps are merged at the MCU. This option is available only when the selected volume
is a Continuous Access XP P-VOL.
• Disable: The S-VOL of this pair accepts I/Os only while the pair is split.
• Suspend Kind: Default is S-VOL.
• S-VOL: The P-VOL accepts all subsequent write I/O operations, and the MCU tracks updates
while the pair is split. Subsequent write I/O operations to the P-VOL are permitted or rejected,
depending on fence level of the pair. This setting is available from the MCU and RCU. Used
this setting to keep the P-VOL online. All Continuous Access XP Asynchronous pairs have
this setting.
• P-VOL Failure (available only for Continuous Access XP Synchronous and only when connected
to the MCU): The MCU rejects all write I/O operations to the P-VOL while the pair is split,
regardless of the P-VOL fence-level setting. Use this setting to maintain synchronization of the
Continuous Access XP pair.
• Asynchronous Parameters:
• Suspend Range:
Group: The MCU and RCU splits all other Continuous Access XP Async pairs in the same
consistency group as the specified pairs. This option is available only when one pair is selected.
LU: The MCU and RCU splits only the specified Continuous Access XP Async pairs (even if error
level of the pair is group).
