7. Click Apply. Within a couple of minutes, the replication set is created and the following changes occur in the Configuration View panel: • Under the primary vdisk: • The selected primary volume changes to a master volume, and is designated as a Primary Volume. • If the secondary volume is on a remote system, the secondary volume appears under the primary volume. • If a replication was performed, under both the primary volume and the secondary volume a replication image appears. • If not already present, the primary volume's snap pool appears. • Under the secondary vdisk: • The secondary volume appears. • If the primary volume is on a remote system, the primary volume appears under the secondary volume. • If a replication was performed, under both the primary volume and the secondary volume a replication image appears. • If not already present, the secondary volume's snap pool appears. Replicating a snapshot If the system is licensed to use remote replication, you can replicate an existing, primary snapshot that is mapped to a host. You can only replicate a snapshot of a volume that is already part of a replication set. If the selected snapshot hasn't already been replicated to a secondary volume, each replication volume in the replication set is requested to replicate the snapshot data. Only snapshot preserved data is replicated; snapshot modified data is not replicated. To replicate a snapshot 1. In the Configuration View panel, right-click a snapshot and select Provisioning > Replicate Snapshot. 2. In the main panel, optionally change the default replication image name. A 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 Initiate Replication. In a few seconds, the following changes occur in the Configuration View panel: • Under both the primary volume and the secondary volume, a replication image appears. Removing replication from a volume If the system is licensed to use remote replication and you no longer want to replicate a volume, you can remove its replication set. When a replication set is removed: • A rollback is automatically performed to the latest available snapshot on the secondary volume to ensure that data is consistent. • Replication volumes associated with the replication set are converted to master volumes. • Any replication images associated with the replication volumes are converted to standard snapshots. Snapshots are converted regardless of the number of snapshots allowed by the system's license. • There is no longer a relationship between the volumes or their snapshots in the two vdisks. To remove replication from a volume 1. In the Configuration View panel, right-click a local primary volume and select Provisioning > Remove Replication Set. 2. In the main panel, click Remove Replication Set. A message indicates whether the task succeeded or failed. If it succeeded, the following changes occur in the Configuration View panel: • Under the primary vdisk: • The primary volume's designation is changed from Primary Volume to Volume 116 Using Remote Snap to replicate volumes

Using Remote Snap to replicate volumes
7.
Click
Apply
. Within a couple of minutes, the replication set is created and the following changes occur
in the Configuration View panel:
•
Under the primary vdisk:
•
The selected primary volume changes to a master volume, and is designated as a Primary
Volume.
•
If the secondary volume is on a remote system, the secondary volume appears under the
primary volume.
•
If a replication was performed, under both the primary volume and the secondary volume a
replication image appears.
•
If not already present, the primary volume’s snap pool appears.
•
Under the secondary vdisk:
•
The secondary volume appears.
•
If the primary volume is on a remote system, the primary volume appears under the secondary
volume.
•
If a replication was performed, under both the primary volume and the secondary volume a
replication image appears.
•
If not already present, the secondary volume’s snap pool appears.
Replicating a snapshot
If the system is licensed to use remote replication, you can replicate an existing, primary snapshot that is
mapped to a host. You can only replicate a snapshot of a volume that is already part of a replication set.
If the selected snapshot hasn’t already been replicated to a secondary volume, each replication volume in
the replication set is requested to replicate the snapshot data. Only snapshot preserved data is replicated;
snapshot modified data is not replicated.
To replicate a snapshot
1.
In the Configuration View panel, right-click a snapshot and select
Provisioning > Replicate Snapshot
.
2.
In the main panel, optionally change the default replication image name. A 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
Initiate Replication
. In a few seconds, the following changes occur in the Configuration View
panel:
•
Under both the primary volume and the secondary volume, a replication image appears.
Removing replication from a volume
If the system is licensed to use remote replication and you no longer want to replicate a volume, you can
remove its replication set. When a replication set is removed:
•
A rollback is automatically performed to the latest available snapshot on the secondary volume to
ensure that data is consistent.
•
Replication volumes associated with the replication set are converted to master volumes.
•
Any replication images associated with the replication volumes are converted to standard snapshots.
Snapshots are converted regardless of the number of snapshots allowed by the system’s license.
•
There is no longer a relationship between the volumes or their snapshots in the two vdisks.
To remove replication from a volume
1.
In the Configuration View panel, right-click a local primary volume and select
Provisioning > Remove
Replication Set
.
2.
In the main panel, click
Remove Replication Set
. A message indicates whether the task succeeded or
failed. If it succeeded, the following changes occur in the Configuration View panel:
•
Under the primary vdisk:
•
The primary volume’s designation is changed from Primary Volume to Volume
