19 Traffic isolation zoning 11. Click OK to close the dialog box. Activating LSAN zones 1. Select a backbone fabric from the Connectivity Map or Product List. 2. Select Configure > Zoning > LSAN Zoning (Device Sharing). The Zone DB tab of the Zoning dialog box displays. 3. Click Activate. The Activate LSAN Zones dialog box displays. 4. Review the information in this dialog box. 5. Click OK to commit the LSAN zones and activate them in the selected fabrics. A message box displays informing you that the zones you change will be saved in the zone database and asking whether you want to proceed. Click Yes to confirm the activation, or No to cancel the activation. When you click Yes, a busy window displays indicating the activation is in progress. A status field informs you whether the activation succeeded or failed. When it succeeds, icons for the active zone configuration and its zones display green. When it fails, the message includes the reason for the failure. 6. Click OK to close the dialog box. If you click OK without having activated the LSAN zones, a message displays informing you that your changes will be lost. Traffic isolation zoning A Traffic Isolation zone (TI zone) is a special zone that isolates inter-switch traffic to a specific, dedicated path through the fabric. A TI zone contains a list of E_Ports, followed by a list of N_Ports. When the TI zone is activated, the fabric attempts to isolate all inter-switch traffic between N_Ports to only those E_Ports that have been included in the zone. The fabric also attempts to exclude traffic not in the TI zone from using E_Ports within that TI zone. Traffic isolation zoning is only supported with domain and port index number members. A TI zone can have failover enabled or disabled. Disable failover if you want to guarantee that TI zone traffic uses only the dedicated path, and that no other traffic can use the dedicated path. Enable failover if you want traffic to have alternate routes if either the dedicated or non-dedicated paths cannot be used. ATTENTION If failover is disabled, use care when planning your TI zones so that non-TI zone devices are not isolated. If disabled failover is not used correctly, it can cause major fabric disruptions that are difficult to resolve. 606 Brocade Network Advisor SAN User Manual 53-1002167-01
