Add Ports to an iSCSI Fault Domain
After you connect additional iSCSI ports to an existing iSCSI network, add the iSCSI ports to the fault domain that corresponds to the
network.
Prerequisites
• If the fault domain is physical, the iSCSI ports that will be added to the fault domain must not belong to a fault domain.
• If the fault domain is physical, each iSCSI port that you want to add to the fault domain must be assigned an IP address, subnet mask,
and gateway in the same network as the iSCSI control port for the fault domain.
• If the fault domain is virtual, the iSCSI ports you want to add to the fault domain must support the Multi-VLAN Tagging feature.
Steps
1. If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
2. Click the Storage tab.
3. In the Storage tab navigation pane, expand Fault Domains, then expand iSCSI and click the fault domain.
4. In the right pane, click Edit Settings.
The Edit Fault Domain Settings dialog box opens.
5. In the Ports table, click Add Ports to Fault Domain.
The Add Ports to Fault Domain dialog box opens.
6. In the Select the ports to add table, select the iSCSI ports to add to the fault domain. All iSCSI ports in the fault domain should be
connected to the same Ethernet network.
7. (Virtual fault domain only) Assign a VLAN IP address to each selected port by editing the corresponding field in the VLAN IP Address
column. Each port must have an IP address in the same network as the iSCSI control port.
