Base Secondary Volume

Select when changing Base Secondary Volume setting.

• Port ID: Port identifier.

• Host Group ID / iSCSI Target ID: Host group or iSCSI target identifier.

• LUN ID: LUN identifier.

• Interval: Interval.

Primary Volume Fence Level

TC only

Whether the P-VOL can be written to when the pair is split due to error.

• Data: The P-VOL cannot be written to.

• Status: The P-VOL can be written to only if the primary storage system can change S-VOL status to PSUE; otherwise no.

• Never: The P-VOL can be written to.

Initial Copy Type

Whether data is copied to the S-VOL when the pair is created.

• Entire Volume: Data is copied. The default.

• None: Data is not copied. If you choose this option, you should confirm the data be equal between the P-VOL and S-VOL.

• Delta: Data is not copied. UR only.

If the pair is Universal Replicator pair, the status will be changed to HOLD or HOLDING as a pair for delta resync.

Copy Pace

TC and GAD only

Number of tracks to be copied per remote I/O during the operation. The default is 15. To change the copy pace, enter a number from 1 to 4:

• 1 is slow. This setting limits the impact on host I/O to maintain storage system performance.

• 2 and 3 is medium.

• 4 is fast. This setting increases the impact on host I/O and might result in decreased storage system performance.

If you enter a number from 5 to 15, the speed of 4 (fast copy pace) is used.

ALUA Mode

GAD only

Whether to enable ALUA mode:

• Enable: Use LDEV by ALUA.

• Disable: Does not use LDEV by ALUA.

Initial Copy Priority

Scheduling order for the initial copy operation. Range is 1 to 256; default is 32. For GAD pairs, this is not displayed.

Error Level

UR only

Whether to split all pairs in the mirror if a failure occurs during this operation:

• LU: Only the failed pair is split.

• Mirror: Pairs in the mirror are split.
