2. In the Storage pane, select a Storage Center.
3. Click the Storage tab.
4. In the Storage tab navigation pane, select the remote Storage Center.
5. In the right pane, click Configure iSCSI Connection. The Configure iSCSI Connection wizard appears.
6. Clear the check box for each iSCSI port that you want to remove from the connection. If you remove all iSCSI ports, the remote
Storage Center is disconnected from the local Storage Center.
7. When you are done, click Finish.
Creating and Managing Replication QoS
Definitions
Replication Quality of Service (QoS) definitions definitions control how bandwidth is used for replications, Live Volumes, and Live
Migrations. Create a QoS definition before you create a replication, Live Volume, or Live Migration.
Create a QoS Definition
Create a QoS definition to control how bandwidth is used to send replication and Live Volume data between local and remote Storage
Centers. A QoS definition is also required to create a Live Migration of a volume.
Prerequisites
The Storage Center for which you want to configure a QoS definition must be added to Storage Manager.
Steps
1. Click the Replications & Live Volumes view.
2. Click the QoS Nodes tab.
3. In the right pane, click Create QoS Node. The Create Replication QoS wizard appears.
4. Select the Storage Center for which you want to create a QoS node, then click Next. The Create page appears.
5. Configure the attributes of the QoS definition.
a) In the Name field, type a name for the QoS definition.
b) In the Link Speed field, specify the speed of the link in megabits per second (Mbps) or gigabits per second (Gbps).
c) Select the Bandwidth Limited check box, then click Finish. The wizard closes and the Edit Replication QoS Schedule dialog
box appears.
6. Configure bandwidth limits for replications and Live Volumes associated with the QoS definition.
a) Limit bandwidth for a time range by clicking the first cell in the range and dragging to the last cell in the range, then right-click the
selection and select the percentage of available bandwidth that can be used.
NOTE:
If you select Blocked for a time range, no data is transferred during that period for all replications, Live
Volumes, and Live Migrations that are associated with the QoS node. This can cause synchronous replications to
become unsynchronized. Live Migrations that use only blocked QoS nodes cannot be completed.
b) Limit bandwidth for other time ranges as needed.
7. When you are finished, click OK.
Rename a QoS Definition
Use the Edit Settings dialog box to rename a QoS Definition.
Steps
1. Click the Replications & Live Volumes view.
2. Click the QoS Nodes tab, then select the QoS definition.
3. In the right pane, click Edit Settings. The Edit Replication QoS dialog box appears.
4. In the Name field, type a name for the QoS definition.
5. Click OK.
