Updating mirror relationships

You can initiate an unscheduled mirror update of the destination. You might have to perform a manual update to prevent data loss due to an upcoming power outage, scheduled maintenance, or data migration.

Before you begin

The mirror relationship must be in a Snapmirrored state.

About this task

For Infinite Volumes with storage classes, if new constituents have been added to the source Infinite Volume since the mirror relationship was created, you cannot use System Manager to update the destination Infinite Volume.

Instead, you should use OnCommand Workflow Automation.

Steps

  1. Click Protection > Relationships.
  2. Select the mirror relationship for which you want to update the data, and click Operations > Update .
  3. Choose one of the following options:
    • Select On demand to perform an incremental transfer from the recent common Snapshot copy between the source and destination volumes.
    • Select Select Snapshot copy and specify the Snapshot copy that you want to transfer.
  4. Optional: Select Limit transfer bandwidth to to limit the network bandwidth used for transfers and specify the maximum transfer speed.
  5. Click Update.
  6. Optional: If you are initiating data transfers on an Infinite Volume, click Run in Background to run the operation in the background.
    It takes longer to update an Infinite Volume than a FlexVol volume.
  7. Verify the transfer status in the Details tab.
