Disabling failover on a traffic isolation zone

NOTE

Traffic isolation zones are only configurable on a Fabric OS device.

If failover is disabled, be aware of the following considerations:

• Ensure that there are non-dedicated paths through the fabric for all devices that are not in a TI

zone.

• If you create a TI zone with just E_Ports, failover must be enabled. If failover is disabled, the

specified ISLs will not be able to route any traffic.

• Ensure that there are multiple paths between switches. Disabling failover locks the specified

route so that only TI zone traffic can use it.

ATTENTION

If failover is disabled, use care when planning your TI zones so that non-TI zone devices are not

isolated. If this feature is not used correctly, it can cause major fabric disruptions that are difficult

to resolve.

Use this procedure to disable failover on a traffic isolation zone.

1. Select Configure > Zoning > Fabric.

The Zoning dialog box displays.

2. Click the Zone DB tab if that tab is not automatically displayed.

3. Select an FC fabric from the Zoning Scope list.

This identifies the target entity for all subsequent zoning actions and displays the zoning

database for the selected entity.

4. Right-click the traffic isolation zone you want to disable failover on in the Zones list and clear

the Configured Failover check box.

5. Click OK or Apply to save your changes.

A message displays informing you that any zones or zone configurations you have changed will

be saved in the zone database, and warning you to make sure no other user is making changes

to the same areas.
