• Display the static and default/dynamic binding of the backbone to show which edge fabrics or FCRs
can access each other.
• Verify that the information in the cache is valid and does not disrupt existing import/export devices.
• Run this command with the quickmode option to derive the LSAN Zone matrix from the current
import/export database.
NOTES The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
OPERANDS If no operands are specified, this command displays the persistent LSAN Zone matrix information. The
following operands are optional:
--add -lsan FID FID | -fcr wwn wwn
Adds the pair of edge fabrics or FCR members that can access each other. If you
specify --add with zero (0) value for FID or 00:00:00:00:00:00:00:00 for wwn, the
command returns the cache to default mode.
--remove -lsan FID FID | -fcr wwn wwn
Removes the entry of the pair of FIDS. If no longer specified, the edge fabric
assumes the default behavior.
--apply -lsan | -fcr | -all
Applies the information from the cache to the persistent memory only if there is no
effect on the existing import/export devices. Otherwise, an error message is
displayed.
--cancel -lsan | -fcr
Cancels the data that was not applied; reverts to the persistent information.
--display -lsan | -fcr | -all
Displays the information saved in the cache.
--fabricview -lsan | -fcr
Views all the static and default/dynamic fabric binding in the backbone.
--verify -lsan | -fcr
Verifies if the LSAN Zone information previously entered and stored in the cache
can be successfully applied. The data is okay if the apply operation does not
cause disruption to the traffic.
--quickmode
Derives the LSAN Zone matrix from the import/export setup.
DIAGNOSTICS Error message (1)
LSAN Matrix in the cache conflicts with existing import/export devices and may disrupt traffic. Please
refer to the man page for the corrective action.
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.
