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 replication destination volume for use on the remote system. The resulting snapshot takes a snapshot license and is independent of the source replication image, which can continue to be used as a sync point. The exported snapshot can be used like any other standard snapshot, including being mapped or deleted. Changes to this snapshot will not affect the replication image. NOTE: The 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 and cannot already exist in a vdisk. A name cannot include a comma, double quote, or backslash. 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 destination volume on the remote system. Changing the external view for a replication set If a replication set's source system goes offline, you can switch the external view to the destination volume on the remote system so hosts can access that volume and the replicated data it contains. Scheduled replications can continue on the remote system while the source system remains offline. If the source system comes back online, you can switch the external view back to the source volume. To change the external view to the destination volume 1. On the destination system, in the Configuration View panel, right-click the replication set's destination volume and select Provisioning > Set Replication External View. 2. In the main panel, select the destination volume in the list. 3. Click Set Replication External View. A message indicates whether the task succeeded or failed. If it succeeded, in the Configuration View panel the volume's designation changes from Destination Volume to External-view Volume. NOTE: The offline source volume remains designated a external-view volume. To change the external view back to the source volume 1. On the source system: a. Create a standard snapshot (page 66) to preserve the source volume's last data level. b. In the Configuration View panel, right-click the source volume and select Provisioning > Set Replication External View. c. In the main panel, select the source volume in the list. d. Click Set Replication External View. A message indicates whether the task succeeded or failed. 2. On the destination system: a. Replicate the destination volume (page 107) to synchronize at the last valid common sync point. This will replicate any data changes made in the destination volume back to the original source volume.

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 replication destination volume for use
on the remote system. The resulting snapshot takes a snapshot license and is independent of the source
replication image, which can continue to be used as a sync point. The exported snapshot can be used like
any other standard snapshot, including being mapped or deleted. Changes to this snapshot will not affect
the replication image.
NOTE:
The 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 and cannot already exist in a vdisk. A name cannot include a comma, double quote, or
backslash.
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
destination volume on the remote system.
Changing the external view for a replication set
If a replication set's source system goes offline, you can switch the external view to the destination volume
on the remote system so hosts can access that volume and the replicated data it contains. Scheduled
replications can continue on the remote system while the source system remains offline.
If the source system comes back online, you can switch the external view back to the source volume.
To change the external view to the destination volume
1.
On the destination system, in the Configuration View panel, right-click the replication set's destination
volume and select
Provisioning > Set Replication External View
.
2.
In the main panel, select the destination volume in the list.
3.
Click
Set Replication External View
. A message indicates whether the task succeeded or failed. If it
succeeded, in the Configuration View panel the volume's designation changes from Destination Volume
to External-view Volume.
NOTE:
The offline source volume remains designated a external-view volume.
To change the external view back to the source volume
1.
On the source system:
a.
Create a standard snapshot (page 66) to preserve the source volume's last data level.
b.
In the Configuration View panel, right-click the source volume and select
Provisioning > Set
Replication External View
.
c.
In the main panel, select the source volume in the list.
d.
Click
Set Replication External View
. A message indicates whether the task succeeded or failed.
2.
On the destination system:
a.
Replicate the destination volume (page 107) to synchronize at the last valid common sync point. This
will replicate any data changes made in the destination volume back to the original source volume.
