fcrLsanMatrix
Corrective actions:
• Any new router added to the backbone fabric automatically triggers a matrix merge. If a router does not
support the matrix merge feature, the router cannot join the backbone fabric. Make sure that all legacy FCR
switches in the backbone support the matrix merge feature, otherwise the feature is not supported.
• Use fcrlsanmatrix --fabricview -lsan | -fcr to confirm that all the switches in the backbone have the same
LSAN and FCR Binding matrix. If not, there are two solutions. The first solution is to modify one FCR or both
to make them the same and then activate the FCRs. The second solution is to zero out the database of one
FCR to signal that this FCR accepts the database from the other FCR once the change is activated.
To zero out the database, execute the following commands:
- fcrlsanmatrix --add -lsan 0 0
- fcrlsanmatrix --add -fcr 00:00:00:00:00:00:00:00 00:00:00:00:00:00:00:00
- fcrlsanmatrix --apply -all
• In a dual backbone configuration, execute fcrlsanmatrix --fabricview on the FCR switches to confirm that the
shared edge fabric FIDs have the same access in both backbones.
• Execute fcrlsanmatrix --display -lsan | -fcr and fcrproxydevshow -a. Check that the LSAN Binding matrix in
the cache is not in conflict with the existing import/export devices that are displayed on the FCR switch. If there
is a conflict, do one of the following:
- Update the LSAN/FCR Binding matrix in the cache to allow access for the FIDs that have imported
devices.
- Remove the conflicting import/export devices by updating the LSAN zone in the edge fabrics.
- Disable the conflicting devices.
Error message (2)
There may be other FCR switches in the backbone that do not support the LSAN Binding feature or do not have
the same fcrlsanmatrix settings.
Please refer to the man page for the corrective action.
Corrective actions:
• Verify that all FCR switches in the backbone support the LSAN Binding features.
• Execute fcrlsanmatrix --fabricview to confirm that all the switches in the backbone have the same LSAN
Binding matrix. If not, clear the LSAN Binding feature on all the switches and reapply the same LSAN Binding
matrix on all the FCR switches in the backbone.
• In a dual backbone configuration, use fcrlsanmatrix --fabricview on the FCR switches to confirm that the
shared edge fabric FIDs have the same access in both backbones.
Refer to the Fabric OS Message Reference manual for further diagnostic information.
Examples To add the LSAN Zone Matrix data (For the following example, assume that the backbone has the following online
edge fabrics (FIDs): 1, 2, 4, 5, 7, 8, and 10. Currently, FIDs 14 and 19 are not available.):
switch:admin> fcrlsanmatrix --add -lsan 4 5
switch:admin> fcrlsanmatrix --add -lsan 4 7
switch:admin> fcrlsanmatrix --add -lsan 10 14
switch:admin> fcrlsanmatrix --add -lsan 10 19
To remove an entry from the LSAN matrix:
switch:admin> fcrlsanmatrix --remove -lsan 10 14
