Monitoring UR pair synchronization rate

You can check the percentage of synchronized data between the P-VOL and S-VOL.

The synchronization rate is displayed in HDvM - SN as follows. In CCI, use the pairdisplay -fc command.

  • When the volume on the local storage system is a P-VOL, the initial copy progress is displayed.
  • When the volume on the local storage system is an S-VOL, the synchronization rate depends on whether the pair is split:
    • If the pair is not split, a hyphen (-) is displayed.
    • If the pair is split, the S-VOL synchronization rate between before and after the split is displayed. For example, if the S-VOL content before and after the split is the same, 100 is displayed.
    CautionIf the pair is split due to initial copy failure, a hyphen (-) is displayed. If initial copy fails, the status Initial copy failed is displayed in the View Pair Properties window.
  • For the following cases, a hyphen (-) is displayed:
    • When the volume in the local storage system is neither a P-VOL nor an S-VOL.
    • When the volume in the local storage system has one of the following pair statuses: HOLD, HOLDING, or HLDE.

Procedure

  1. In the Explorer pane, expand the Storage Systems tree.

  2. Expand the target storage system tree, expand Replication, and click Remote Replication.

  3. In the UR Pairs tab, select the pair whose synchronization rate you want to monitor.

  4. Click More Actions View Pair Synchronization Rate.

    Clicking Refresh View displays the latest synchronization rate.
