Viewing and configuring LSAN zones
10
• A required name convention. The name of an LSAN zone begins with “LSAN_”. The LSAN name
is case insensitive; for example, lsan_ is equivalent to LSAN_, Lsan_ and so on.
• Members must be identified by their port WWN, because PIDs are not necessarily unique
across fabrics.
To enable device sharing across multiple fabrics, you must create LSAN zones on the edge fabrics
(and optionally on the backbone fabric, as well), using normal zoning operations to create zones
with names that begin with the special prefix “LSAN_”, and adding host and target WWNs from
both local and remote fabrics to each local zone as desired. Zones on the backbone and on
multiple edge fabrics that share a common set of devices will be recognized as constituting a single
multi-fabric LSAN zone, and the devices that they have in common will be able to communicate
with each other across fabric boundaries.
Follow the procedure described in “Creating and populating zones” on page 104 to create LSAN
zones.
VIEWING LSAN DEVICES
An LSAN device can be a “physical device,” meaning that it physically exists in the fabric, or it can
be a “proxy device.” A proxy device represents a real device in a remote fabric. It has a name server
entry and is assigned a valid port ID. When a proxy device is created in a fabric, the real device is
considered to be imported into this fabric. The presence of a proxy device is required for interfabric
device communication.
The LSAN Devices tab displays information about the physical and proxy devices and displays these
devices in a tree on the left side of the window. (If FC-FC Routing is disabled, the tables and tree
nodes in this tab are empty.)
Click the LSAN Devices element in the tree to display a count of all the physical and proxy LSAN
devices. Note that this count is for all of the LSAN fabrics.
