Primary Volume

The P-VOL information.

Values:

• LDEV ID: The P-VOL's LDEV identifier

• LDEV Name: The P-VOL's LDEV name

• Capacity: The P-VOL's volume capacity

• CLPR: The P-VOL's CLPR number

Copy Type

The pair type.

Values:

• SI-L1: SI L1

• SI-L2: SI L2

• TI: HTI

Snapshot Group

HTI only.

The snapshot group name.

If you have not assigned the pair to a snapshot group, this item is blank.

Status

The status for the pair.

For more information about pair status, click Show All Contents and then select In-System Replication to navigate to the desired software and status information.

Snapshot Date

HTI only.

The date and time that you acquired the snapshot.

Secondary Volume

The S-VOL information.

Values:

• LDEV ID: The S-VOL's LDEV identifier

• LDEV Name: The S-VOL's LDEV name

• Capacity: The S-VOL's volume capacity

• CLPR: The S-VOL's CLPR number

Pool Name (ID)

HTI only.

The pool name and identification number.

Mirror Unit

The mirror unit number.

Resync Type

The type of resynchronization.

Values:

• Normal Copy (Primary > Secondary)

A full forward resynchronization from the P-VOL to the S-VOL. The differential data is updated to the S-VOL.

• Reverse Copy (Secondary > Primary)

Resyncs the pairs from S-VOL to P-VOL. The differential data is updated to the P-VOL.

You cannot use Reverse Copy with the following pair:

• An SI L2 pair.

• Quick Resync (Primary > Secondary)

A forward resynchronization from the P-VOL to the S-VOL where data is not copied or resynchronized. The volumes are paired ("PAIR" status). The update copy operation copies the differential data to the S-VOL.You can use Quick Resync with the SI pairs only.

• Quick Restore (Secondary > Primary)

Swaps the P-VOL and S-VOLs. The update copy operation copies the differential data to the S-VOL. Only SI pairs can be selected. You cannot use Quick Restore with the following pairs:

• SI L2 pairs

• Only one of the P-VOL or S-VOL is DP-VOL pair

• SI pairs which has HTI pairs in P-VOL or/and S-VOL pairs

Default: Normal Copy (Primary > Secondary)

For more information about the methods you can use to resynchronize pairs, see the topic on types of pair resynchronization by clicking Show All Contents and then selecting In-System Replication to navigate to the desired software and information.

Copy Pace

SI only.

The system option that determines the rate at which you want the VSP G200, G400, G600 storage system to copy data.

Values:

• Slower: Improved host server I/O performance but slower processing speed.

• Medium: Average processing speed and host server I/O performance.

• Faster: Faster processing speed but slower host server I/O performance.
