R21xx-HP FlexFabric 11900 FCoE Command Reference

Usage guidelines

The fabric reconfiguration triggers principal switch selection, domain ID assignment, and FC address

assignment throughout the fabric.

Auto fabric reconfiguration occurs in the event of network faults or fabric merges as follows:

• When two fabrics are merged:

{ The switches automatically perform a disruptive reconfiguration if the domain ID lists overlap.

{ The system automatically performs a non-disruptive reconfiguration if the principal switch

information of the two fabrics is different and the domain ID lists are not empty or overlapping.

• When the principal switch in a fabric is down, the system automatically performs a non-disruptive

reconfiguration.

This command is available only when the fabric configuration function is enabled.

Examples

# Enable the auto fabric reconfiguration function for the switch in VSAN 1.

<Sysname> system-view

[Sysname] vsan 1

[Sysname-vsan1] domain auto-reconfigure enable

Related commands

Use domain configure enable to enable the fabric configuration function for the switch in a specified

VSAN.

Use undo domain configure enable to disable the fabric configuration function for the switch in a

specified VSAN.

Syntax

Default

The fabric configuration function is enabled in each VSAN.

Usage guidelines

After being enabled with the fabric configuration function, FCF switches exchange messages to select the

principal switch. Then, the principal switch dynamically assigns domain IDs to all switches in the fabric.

Therefore, to dynamically build a fabric, you must enable the fabric configuration function on switches.

To statically set up a fabric, you must disable the fabric configuration function on switches and manually

configure domain IDs for the switches.
