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.
