HP StorageWorks Fabric OS 6.1.1 administrator guide (5697-0235, December 2009)

334 Using the FC-FC routing service
creating and updating the LSAN fabric matrix. See the Fabric OS Command Reference for a complete
description of this command.
Best practice: Use this feature in a backbone fabric in which all FC routers are running Fabric OS 6.1.0 or
later.
When you set up LSAN zone binding on the local FC router (running Fabric OS 6.1.0 or later), the resultant
matrix database is automatically distributed to all of the 6.1.0 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 6.1.0.
If a new FC router joins the backbone fabric, the matrix database is automatically distributed to that FC
router.
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 make sure that both backbone fabrics have the same matrix settings.
FC router matrix definition
Depending on how the backbone fabric is structured, you can specify pairs of FC routers that can access
each other. For the metaSAN shown in Figure 41 on page 333, 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.
LSAN fabric matrix definition
With LSAN zone binding, you can specify pairs of fabrics that can access each other. Using the metaSAN
shown in Figure 41 on page 333 as an example, the following edge fabrics can access each other:
• Fabric 1 and Fabric 2
• Fabric 2 and Fabric 3
• Fabric 4 and Fabric 5
• Fabric 5 and Fabric 6
You can use the fcrLsanMatrix command with the -lsan option to create the corresponding LSAN fabric
matrix:
fcrlsanmatrix --add -lsan 1 2
fcrlsanmatrix --add -lsan 2 3
fcrlsanmatrix --add -lsan 4 5
fcrlsanmatrix --add -lsan 5 6
Fabrics that are not specified are part of the default binding and can access other edge fabrics that are not
specified. So Fabrics 7, 8, and 9 can access each other, but cannot access Fabrics 1 through 6.
