2. In the secondary system: a. Start the snap pools' vdisks. For details see Starting a vdisk on page 119. b. Start the secondary volumes' vdisks. c. Reattach the secondary volumes. To reattach a secondary volume 1. In the Configuration View panel, right-click the secondary volume and select Provisioning > Reattach Replication Volume. 2. In the main panel, click Reattach Replication Volume. A message indicates whether the task succeeded or failed. • If the task succeeds, the secondary volume's status changes to "Establishing proxy" while it is establishing the connection to the remote (primary) system in preparation for replication; then the status changes to Online. The replication set is ready to resume replication operations. • If the reattach operation fails and says it is unable to get the primary volume's link type, the vdisk that contains the secondary volume may not have completed its startup activities. Wait approximately one minute for these activities to complete, then retry the operation. If this message continues to occur, check the event log to better understand the condition and for an indication of how to correct it. Exporting a replication image to a snapshot If the system is licensed to use remote replication, you can export a replication image to a new standard snapshot. For example, you could export a replication image from a secondary volume for use on the remote system. The standard snapshot will reside in the same snap pool, take a snapshot license, and be independent of the primary replication image, which can continue to be used as a sync point. The standard snapshot can be used like any other standard snapshot, and changes to it will not affect the replication image. The standard snapshot is subject to the snap pool's deletion policies. If the snap pool reaches its critical threshold, the snapshot may be deleted, even if it is mapped. If you want to preserve the standard snapshot's data, you can create a standard volume from the snapshot; see Creating a volume copy on page 69. NOTE: The export task will not succeed if the resulting snapshot would exceed license limits. To export a replication image to a snapshot 1. In the Configuration View panel, right-click a replication image and select Provisioning > Export Snapshot. 2. In the main panel, optionally change the default name for the snapshot. A snapshot name is case sensitive; cannot already exist in a vdisk; cannot include a comma, double quote, or backslash; and can have a maximum of 20 bytes. 3. Click Export Snapshot. A message specifies whether the task succeeded or failed. 4. Click OK. If the task succeeds, in the Configuration View panel the snapshot appears under the secondary volume on the remote system. Changing the primary volume for a replication set If a replication set's primary system goes offline, you can set the secondary volume to be the primary volume so hosts can access that volume and the replicated data it contains. Scheduled replications can continue on the remote system while the primary system remains offline. When the secondary volume becomes the primary volume, it only retains the replication images that the primary volume had and deletes any images that the primary volume did not have. Because the secondary volume may not have successfully replicated all the images associated with the primary volume, the secondary volume might have a subset of the primary volume's images. 120 Using Remote Snap to replicate volumes
