Configuring the fabric reconfiguration

IMPORTANT:
The fabric reconfiguration function takes effects only when the fabric configuration function is enabled.
The fabric reconfiguration occurs in the case of a network reconstruction (for example, two fabrics are
merged) or external intervention (for example, the administrator uses a command to initiate
reconfiguration). The fabric reconfiguration triggers principal switch selection, domain ID assignment,
and FC address assignment throughout the fabric.
The fabric reconfiguration includes the following categories:
Disruptive reconfiguration—Floods the Reconfigure Fabric (RCF) frames throughout the fabric, and
•
notifies all switches to perform a disruptive reconfiguration. During the reconfiguration procedure,
each switch clears all data for renegotiation, and data transmission in the fabric is disrupted.
Non-disruptive reconfiguration—Floods the Build Fabric (BF) frames throughout the fabric, and
•
notifies all switches to perform a non-disruptive reconfiguration. During the reconfiguration
procedure, each switch tries to save the last running data for its domain ID to remain unchanged.
Thus, data transmission in the fabric is not disrupted.
Depending on the triggering conditions, the fabric reconfiguration falls into auto reconfiguration and
manual reconfiguration.
When two fabrics are merged:
•
The switches automatically perform a disruptive reconfiguration if the domain ID lists overlap.
