Resync Pairs window

Use this window of the Resync Pairs wizard to resynchronize a pair.

For more information about using this wizard, see the topic on resynchronizing pairs by selecting In-System Replication to navigate to the desired software and information.

Selected Pairs table

The following table describes the items in this table in the Resync Pairs window of the Resync Pairs wizard.

Item	Description
Primary Volume	The P-VOL information. Values: LDEV ID: The P-VOL's LDEV identifier LDEV Name: The P-VOL's LDEV name Attribute: The P-VOL's attribute. Capacity: The P-VOL's volume capacity CLPR: The P-VOL's CLPR ID
Copy Type	The pair type. Values: SI-L1: SI L1 SI-L2: SI L2 TI: HTI
Snapshot Group	The snapshot group name. For non-HTI pairs, a hyphen is displayed. If the pair is a Thin Image pair and the snapshot group is not set, a blank is displayed.
Status	The status of the pair. For more information about pair status, select In-System Replication to navigate to the desired software and status information.
Snapshot Date	HTI pairs only. The date and time the snapshot was acquired. For non-HTI pairs, a hyphen is displayed.
Secondary Volume	The S-VOL information. Values: LDEV ID: The S-VOL's LDEV identifier LDEV Name: The S-VOL's LDEV name Attribute: The S-VOL's attribute. Capacity: The S-VOL's volume capacity CLPR: The S-VOL's CLPR ID
Pool Name (ID)	The pool name and identification number. For non-HTI pairs, a hyphen is displayed.
Mirror Unit	The mirror unit number.
Cascade	Indicates whether cascade pairs can be created. Enabled: Cascade pairs can be created. Disabled: Cascade pairs cannot be created. For non-HTI pairs, a hyphen is displayed.
Type	The pair type. Snapshot: The pair has the snapshot attribute. Clone: The pair has the clone attribute For non-HTI pairs, a hyphen is displayed.
Topology ID	The topology ID, which indicates the layer of the pair based on the mirror unit. The topology ID consists of the LDEV ID of the volume (root volume for Thin Image pairs), which is the base of the target pair, and the mirror unit number.
Resync Type	The type of resynchronization. Values: Normal Copy (Primary Secondary) (default) 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 SI L2 or SIz pair sharing the P-VOL with an FCv2/FCSE 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 SI or SIz 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. Can be selected for SI or SIz pairs. You cannot use Quick Restore with the following pairs: SI L2 pairs Only one of the P-VOL or S-VOL is DP-VOL SI pairs with HTI pairs in P-VOL and S-VOL SIz pairs sharing the P-VOL with an FCv2/FCSE pair For more information about the methods you can use to resynchronize pairs, see the topic on types of pair resynchronization by selecting In-System Replication to navigate to the desired software and information.
Copy Pace	SI and SIz pairs only. For HTI pairs, you cannot select the rate. The system option that determines the rate at which you want the storage system to copy data. A hyphen appears for HTI pairs. 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.
