Grouping Fibre Channel I/O Ports Using Fault
Domains
Front-end ports are categorized into fault domains that identify allowed port movement when a controller reboots or a port fails.
Ports that belong to the same fault domain can fail over to each other because they have connectivity to the same resources.
NOTE: Fault domains cannot be added or modified on SCv2000 or SCv3000 series storage systems. Storage Center
creates and manages fault domains on these systems.
Create a Fibre Channel Fault Domain
Create a Fibre Channel fault domain to group Fibre Channel ports for failover purposes.
Prerequisites
The Fibre Channel ports to add to the fault domain must be unconfigured. Ports that are already added to a fault domain or
designated as back-end ports cannot be added to a new fault domain.
● In virtual port mode, all Fibre Channel ports that are connected to the same Fibre Channel fabric should be added to the
same fault domain.
● In legacy mode, each pair of primary and reserved ports connected to the same Fibre Channel fabric should be added to a
unique fault domain. The primary port should be located on a different controller than the secondary port.
About this task
NOTE:
Fibre Channel ports are always configured in Virtual Port Mode on SCv2000 and SCv3000 series storage systems.
Legacy Mode is not supported.
Steps
1. If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.

3. In the Storage tab navigation pane, click Fault Domains, then click Create Fibre Channel Fault Domain.
The Create Fault Domain dialog box opens.
4. In the Name field, type a name for the fault domain.
5. In the Ports table, select the Fibre Channel ports to add to the fault domain. All Fibre Channel ports in the fault domain
should be connected to the same Fibre Channel fabric
6. Click OK.
Rename a Fibre Channel Fault Domain
