Resuming SnapMirror operations

After completing a nondisruptive upgrade or downgrade, you must resume any SnapMirror relationships that were suspended.

Before you begin

Existing SnapMirror relationships must have been suspended by using the snapmirror quiesce command, and the cluster must have been nondisruptively upgraded or downgraded.

  1. Resume transfers for each SnapMirror relationship that was previously quiesced: snapmirror resume *

    This command resumes the transfers for all quiesced SnapMirror relationships.
  2. Verify that the SnapMirror operations have resumed: snapmirror show

    Example

    TDC-DM7K::> snapmirror show

    Source            Destination  Mirror  Relationship  Total             Last

    4 entries were displayed.

    For each SnapMirror relationship, verify that the Relationship Status is "Idle". If the status is "Transferring", wait for the SnapMirror transfer to complete, and then reenter the command to verify that the status has changed to "Idle".

After you finish

For each SnapMirror relationship that is configured to run on a schedule, you should verify that the first scheduled SnapMirror transfer completes successfully.
