Traffic Isolation Zoning

Determining ports for the TI Zone

To find the device ports, use the MVS display command. The following example will display the
paths to device 1002 and where it is connected:
D M=DEV(1002)
Response is:
DEVICE 1002

DEST LINK ADDRESS
where DD= domain ID of switch//
PATH ONLINE
CHP PHYSICALLY ONLINE Y
PATH OPERATIONAL

Enhanced TI Zoning

Enhanced Traffic Isolation Zones allow you to specify a preferred and exclusive path through a
cascaded fabric for a particular flow by defining a set of devices or ports to appear in more than
one Enhanced TI Zone. A preferred path is one that has failover enabled and an exclusive path has
failover disabled. An exclusive path in the following topologies is beneficial as it will limit the
number of hops between switches:
•
•
•
Enhanced TI Zoning for the topologies listed above is available only on the following platforms
running Fabric OS v6.4.0 or later:
•

•
Triangular topology
The triangular topology shown in
center recovery functions. In this topology, a switch is located in each of three sites and connected
to the other two forming a triangle. In most environments, the purpose of this configuration is to
give the host application the ability to connect to storage media at the other two sites, which allow
it to recover from an outage at either site. Meanwhile, the storage systems constantly synchronize
between the two storage sites.
