Administrator Guide

Rename a Fibre Channel Fault Domain
The fault domain name allows administrators to identify the fault domain.
1. Select a Storage Center from the Storage view. (Data Collector connected Storage Manager Client only)
2. Click the Storage tab.
3. In the Storage tab navigation pane, expand Fault Domains → Fibre Channel, then select the fault domain.
4. In the right pane, click Edit Settings. The Edit Settings dialog box opens.
5. In the Name eld, type a name for the fault domain.
6. Click OK.
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 IO 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. Select a Storage Center from the Storage view. (Data Collector connected Storage Manager Client only)
2. Click the Storage tab.
3. In the Storage tab navigation pane, expand Fault Domains→ Fibre Channel, then select the fault domain.
4. In the right pane, click Delete. The Delete Fault Domain dialog box appears.
5. Click OK.
Grouping iSCSI 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.
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 IO port. An iSCSI IO
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 IO port. An iSCSI IO
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.
