• Initial is displayed when neither data volume is paired yet (initial copy not performed).

Status

Status of the mirror.

Resync Mode

The type of mirror resynchronization to be performed.

• Normal: Resynchronizes split pairs in the mirror that are in PSUS or PSUE status (open systems) or Suspend status (mainframe systems).
• Delta: Runs the delta resync operation for all pairs in the mirror.
• Return to standby: Recovers the status of pairs in the mirror from HLDE to HOLD for open systems (Hlde to Hold for mainframe).

• Model/Serial Number: Storage system model name and serial number.
• Journal ID: Journal identifier.

Path Group ID

Number of Data VOLs

Number of volumes associated with the journal.

With the delta resync configuration, the number of data volumes registered to the journal of the mirrors not for delta resync is displayed. The number of volumes registered to the journal of the delta resync mirrors (whose status is Hold, Holding, or Hold(Failure)) is not displayed.

Data Capacity

Total capacity of all the data volumes.

With the delta resync configuration, the total capacity of the data volumes registered to the journal of the mirrors not for delta resync is displayed. The total capacity of the data volumes registered to the journal of the delta resync mirrors (whose status is Hold, Holding, or Hold(Failure)) is not displayed.

• The column is blank if the remote command device is not assigned to the mirror.
• A hyphen (-) indicates the remote command device cannot be assigned to the mirror.

CTG ID

Consistency group identifier.

CTG Utilization

Whether the consistency group is shared by multiple storage systems.

• Single: The consistency group consists of a single pair of primary and secondary storage systems.
• Multi: The consistency group consists of multiple storage systems.

Delta Resync Failure

Processing to take place if delta resync cannot be performed.

• Entire Copy: All data in the P-VOL is copied to the S-VOL.
• No Copy: No data is copied to the S-VOL.
