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