Deleting Continuous Access Xp Volume Pairs (Pairsplit-S) - HP xp12000 User Manual

• Port, Group, and LUN of the selected LU.
• S/N and SSID of the RCU (MCU if connected to the RCU).
• Priority: Initial copy priority (blank after initial copy operation is complete).
• Pace: Number of tracks (1-15) for the copy.
• Fence: Fence level.
• Never: Never fence the operation.
• Data: Fence when the MCU cannot successfully execute an update copy operation for any reason.
• Status: Fence only if the MCU cannot change the S-VOL status to the same status as the P-VOL. For
synchronous mode only.
• ErrLvl: Error level of pair (Group or LU) (Async LUs only).
• Range:
• Group: Resync all split or suspended Continuous Access XP Async pairs in the same group as
selected pair.
• LU: Resync only selected Continuous Access XP Async pairs.

Deleting Continuous Access XP volume pairs (Pairsplit-S)

Delete a Continuous Access XP pair from the MCU only when it is no longer necessary to maintain a
remote copy of the P-VOL. When a Continuous Access XP pair is deleted from the MCU, the MCU stops all
Continuous Access XP copy operations for that pair and changes the pair status of the P-VOL and S-VOL to
SMPL. After a Continuous Access XP pair is deleted, the MCU continues accepting all subsequent write
I/O operations to the P-VOL and does not track P-VOL updates.
Delete a Continuous Access XP pair from the RCU only for disaster recovery (see
disaster recovery
the RCU changes the S-VOL pair status to SMPL, but does not change the pair status of the corresponding
P-VOL. When the MCU performs the next Continuous Access XP operation, the MCU detects that the S-VOL
status changed, and changes the P-VOL status to PSUS-pairsplit-S to RCU. To restart a pair deleted from the
RCU, delete the pair from the MCU, and create the pair from the MCU using the appropriate initial copy
option (Entire or No Copy) to restart the pair.
To delete all Continuous Access XP Async pairs in a consistency group, delete pairs from the MCU. The
Continuous Access XP pair status changes to Deleting when the pairsplit-S operation is accepted by the
MCU and RCU, and changes to SMPL after the internal pairsplit-S process is complete. To delete
Continuous Access XP Async pairs according to consistency status (for example, for disaster recovery),
delete the pairs from the RCU.
CAUTION: When you delete a Continuous Access XP pair from the RCU, remember that the S-VOL and
P-VOL are identical (for example, same volume label), and take appropriate precautions to prevent a
system problem due to duplicate volumes.
Use the Pairsplit-S command to delete one or more Continuous Access XP pairs. When the Pairsplit-S
command is selected, the Pairsplit-S pane appears. Use the Pairsplit-S pane to change Pairsplit-S options
