Configure Back-End IO Ports
On SCv2000 series controllers, ports must be configured before they can be used as back-end ports. After Storage Manager
configures the port, it is also added to a fault domain.
Prerequisites
• The Storage Center must be a SCv2000 series storage system.
• The port cannot be already configured.
Steps
1. Expand the Dell Storage Manager menu, and then click Storage.
2. In the SC Series tab, select a Storage Center to open the Storage Center view.
3. Click the Storage tab, and then click the Fault Domains subtab.
4. Click the Unconfigured Ports tab.
5. Select an unconfigured SAS IO port.
6. Click Configure as Back-End.
Storage Manager configures the port as a back-end port.
Grouping Fibre Channel IO 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: For user interface reference information, click Help.
Create a Fibre Channel Fault Domain
Create a Fibre Channel fault domain to group FC ports for failover purposes.
Prerequisites
The FC ports that will be added 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 FC ports that are connected to the same FC fabric should be added to the same fault domain.
• In legacy mode, each pair of primary and reserved ports connected to the same FC 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 must be configured in Virtual Port Mode when using SCv2000 series controllers. Legacy
Mode is not supported.
Steps
1. Expand the Dell Storage Manager menu, and then click Storage.
2. In the SC Series tab, select a Storage Center to open the Storage Center view.
3. Click the Storage tab, and then click the Fault Domains subtab.
4. In the Fault Domains subtab, click New → Fibre Channel Fault Domain. The Create Fibre Channel Fault Domain dialog box
