Virtual Fabric Considerations For Traffic Isolation Routing; Dedicated Path With Virtual Fabrics; Creating A Ti Zone In A Logical Fabric - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

• Use care if defining TI zones with ports that are shared across Admin Domains because of the limitation
that a given port can appear in only one TI zone.
Best practice: Do not use ports that are shared across Admin Domains in a TI zone.

Virtual Fabric considerations for Traffic Isolation Routing

This section describes how TI zones work with Virtual Fabrics. See Chapter 6,
on page 173 for information about the Virtual Fabrics feature, including Logical Switches and Logical
Fabrics.
TI zones can be created in a Logical Fabric like in regular fabrics, with the following exceptions:
• The disable failover option is not supported in Logical Fabrics that use XISLs.
• To create a TI zone for a Logical Fabric that uses XISLs, you must create two TI zones: one in the Logical
Fabric and one in the base fabric. The combination of TI zones in the base fabric and Logical Fabric
sets the path through the base fabric for Logical Switches.
The TI zone in the Logical Fabric includes the extended XISL (XISL) port numbers, as well as the F_Ports and
ISLs in the Logical Fabric.
The TI zone in the base fabric reserves XISLs for a particular Logical Fabric. The base fabric TI zone should
also include ISLs that belong to Logical Switches participating in the Logical Fabric.
Figure 50 shows an initiator and target in a Logical Fabric (FID1). The dotted line indicates a dedicated
path between initiator and target. The dedicated path passes through the base fabric over an XISL.
(Figure 50 shows only physical ISLs, not logical ISLs.) To create the TI zones for this dedicated path, you
must create a TI zone in the Logical Fabric (FID1) and one in the base fabric.
