Create a SAS Fault Domain

Create a SAS fault domain to group SAS front-end ports for failover purposes on SC4020 or SC5020 controllers.

1. If the Dell 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, select Fault Domains, then click Create SAS 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 SAS ports to add to the fault domain.
   When pairing SAS ports into the fault domain:

   • Use one port from each controller.
   • Make sure the paired ports have the same port number and are connected to the same server.
6. Click OK.
