When you have a protection relationship that is broken because the source volume is disabled and the destination is made a read/write volume, reverse resynchronization enables you to reverse the direction of the relationship so that the destination becomes the new source and the source becomes the new destination.

Reverse Resync dialog box

When you have a protection relationship that is broken because the source volume is disabled and the destination is made a read/write volume, reverse resynchronization enables you to reverse the direction of the relationship so that the destination becomes the new source and the source becomes the new destination.

When a disaster disables the source volume in your protection relationship, you can use the destination volume to serve data by converting it to read/write, while you repair or replace the source, update the source, and reestablish the relationship. When you perform a reverse resync operation, data on the source that is newer than the data on the common Snapshot copy is deleted.

Before reverse resync

Displays the source and destination of a relationship before a reverse resync operation.

  • Source Volume

    The name and location of the source volume before a reverse resync operation.

  • Destination Volume

    The name and location of the destination volume before a reverse resync operation.

After reverse resync

Displays what the source and destination of a relationship is after a reserve resync operation.

  • Source Volume

    The name and location of the source volume after a reverse resync operation.

  • Destination Volume

    The name and location of the destination volume after a reverse resync operation.

Command buttons

The command buttons enable you to perform the following actions:

  • Submit

    Begins the reverse resynchronization process.

  • Cancel

    Closes the Reverse Resync dialog box without initiating a reverse resync operation.
