How LSAN zone binding works
LSAN zone binding uses an FC router matrix, which specifies pairs of FC routers in the backbone
fabric that can access each other, and an LSAN fabric matrix, which specifies pairs of edge fabrics
that can access each other.
You set up LSAN zone binding using the fcrLsanMatrix command. This command has two options:
-fcr and -lsan. The -fcr option is for creating and updating the FC router matrix, and the -lsan option
is used for creating and updating the LSAN fabric matrix.
NOTE
Best practice: Use this feature in a backbone fabric in which all FC routers are running Fabric OS
v6.1.0 or later.
When you set up LSAN zone binding on the local FC router (running Fabric OS v6.1.0 or later), the
resultant matrix database is automatically distributed to all of the v6.1.0 or later FC routers in the
backbone fabric. You do not need to set up LSAN zone binding on the other FC routers unless those
FC routers are running Fabric OS versions earlier than v6.1.0.
If a new FC router joins the backbone fabric, the matrix database is automatically distributed to
that FC router.
Note the following for FC routers running a Fabric OS version earlier than 6.1.0:
•The matrix database is not automatically distributed from this FC router to other FC routers.
•You must manually configure the LSAN fabric matrix on these FC routers to match the other FC
routers in the backbone fabric.
If you have a dual backbone configuration, where two backbone fabrics share edge fabrics, the
LSAN fabric matrix and FC router matrix settings for the shared edge fabrics must be the same on
both backbone fabrics. The matrix databases are not automatically propagated from one backbone
fabric to another, so you must ensure that both backbone fabrics have the same matrix settings.
NOTE
You can use LSAN zone binding along with the LSAN tagging to achieve better scalability and
performance. See “LSAN zone policies using LSAN tagging” on page 481 for information about using
the Enforce LSAN tag.
FC router matrix definition
Depending on the structure of the backbone fabric, you can specify pairs of FC routers that can
access each other. For the metaSAN shown in Figure 75, the following FC routers can access each
other:
•FC router 1 and FC router 2
•FC router 3 and FC router 4
Because there is no device sharing between the two groups of FC routers, you can use the
fcrLsanMatrix command with the -fcr option to create the corresponding FC router matrix:
fcrlsanmatrix --add -fcr wwn1 wwn2
fcrlsanmatrix --add -fcr wwn3 wwn4
where wwn1, wwn2, wwn3, and wwn4 are the WWNs of the four FC routers.
Now edge fabrics 1, 2, 3, 7, and 8 can access each other, and edge fabrics 4, 5, 6, and 9 can
access each other; however, edge fabrics in one group cannot access edge fabrics in the other
group.
