Contributors

You can use the Suspend option and Resume option to control when to synchronize the data on the primary volume and the secondary volume in a mirrored pair.

About this task

If a mirrored pair is manually suspended, the mirrored pair will not synchronize until it is manually resumed.

Steps

  1. Select Storage › Synchronous Mirroring.

  2. Select the mirrored pair that you want to suspend or resume, and then select either More › Suspend or More › Resume.

    The system displays a confirmation.

  3. Select Yes to confirm.

Results

System Manager performs the following actions:

  • Either suspends or resumes data transfer between the mirrored pair without removing the mirror relationship.

  • For a suspended mirrored pair:

    • Displays Suspended in the Mirrored Pair table.

    • Logs any data that was written to the primary volume of the mirrored pair while synchronization is suspended.

  • For a resumed mirrored pair, writes the data automatically to the secondary volume of the mirrored pair when synchronization is resumed. A full synchronization is not required.
