Parameters

disruptive: Initiates a disruptive reconfiguration. If you do not specify this keyword, the command initiates a nondisruptive reconfiguration.

Usage guidelines

Only FCF switches and VSANs operating in FCF mode support this command.

This command takes effect only when the fabric configuration feature is enabled.

A fabric reconfiguration triggers a principal switch selection phase.

A fabric reconfiguration can be disruptive or nondisruptive.

• Disruptive reconfiguration—Floods 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 and performs renegotiation, and data transmission in the fabric is disrupted.

• Nondisruptive reconfiguration—Floods Build Fabric (BF) frames throughout the fabric and notifies all switches to perform a nondisruptive 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.

For fabric settings that do not take effect immediately (for example, switch priority), you can perform a disruptive reconfiguration to make them take effect.

Examples

# Manually initiate a disruptive reconfiguration in VSAN 1.
