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 congured for legacy mode. In virtual port mode, fault domains cannot
be deleted.
The fault domain must contain no FC ports.
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, expand Fault Domains, then expand Fibre Channel and select a fault domain.
The FC Fault Domain view is displayed.
4 Click Delete FC Fault Domain.
The Delete FC Fault Domain dialog box opens.
5 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 modied 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 congured 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 congured 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 Storage Manager.
Multi-VLAN Tagging
If a Storage Center supports multi-VLAN tagging, a maximum of 64 VLAN IDs can be congured for each iSCSI I/O port. An iSCSI I/O port
can belong to up to 64 fault domains—one for each VLAN.
Multi-VLAN tagging is supported by Storage Centers that meet the multi-VLAN tagging requirements.
