Delete a Fibre Channel Fault Domain
Delete a Fibre Channel fault domain if all ports have been removed and it is no longer needed.
Prerequisites
• The Storage Center Fibre Channel front-end I/O ports must be congured for legacy mode. In virtual port mode, fault domains cannot
be deleted.
• The fault domain must contain no FC ports.
Steps
1 If you are connected to a Data Collector, select a Storage Center from the drop-down list in the left navigation pane.
2 From the SYSTEM menu, select Ports.
The Ports view is displayed.
3 Click the Front End Ports tab.
4 Expand Fibre Channel and click the fault domain link.
The FC Fault Domain view is displayed.
5 On the Summary tab, click (More Actions) and select Delete FC Fault Domain from the drop-down menu.
The Delete FC Fault Domain dialog box opens.
6 Click OK.
Grouping iSCSI 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 modied on SCv2000 or SCv3000 series storage systems. Storage Center creates and
manages fault domains on these systems.
iSCSI VLAN Tagging Support
iSCSI ports in a fault domain can be congured to use a VLAN ID. For each Storage Center, one of two levels of VLAN functionality is
available depending on the Storage Center OS version, Storage Center controller model, and iSCSI hardware. Basic VLAN functionality is
referred to as single-VLAN tagging, and enhanced VLAN functionality is referred to as multi-VLAN tagging.
Single-VLAN Tagging
If a Storage Center supports single-VLAN tagging, a maximum of 1 VLAN ID can be congured for each iSCSI I/O port. An iSCSI I/O port
can belong to only one fault domain, and all ports in the same fault domain use the same VLAN ID.
Single VLAN tagging is supported by all Storage Center versions compatible with Unisphere.
