For example: FCR:Admin > fcrlsanmatrix --fabricview -lsan LSAN MATRIX is activated Fabric ID 1 Fabric ID 2 4 5 4 7 10 19 Default LSAN Matrix: 1 2 8 Dual backbone configuration When dual backbones share edge fabrics, one of the backbones is selected to be the owner of the edge fabric which sends device state updates to the other backbone through the shared edge fabric. When the 'LSAN Zone binding' feature is enabled, the LSAN Zone Matrix settings for the shared edge fabrics must be the same on both backbones. Both backbone fabrics must have the same LSAN Zone Matrix settings. If the settings are different, the outcome will be inconsistent. Both backbone fabrics will end up having the setup of the owner fabric which can change on reboot or on a port disable or enable. Setting the maximum LSAN count You can set the maximum number of LSAN zones, or LSAN count, that can be configured on the edge fabrics. By default, the maximum LSAN count is set to 3000. You can increase the maximum LSAN count to 5000 without disabling the switch. The maximum number of LSAN devices supported is 10,000, which includes both physical and proxy devices. If you have 3000 LSAN zones, but have not exceeded the 10,000 device limit, you can increase the LSAN count to 5000. All FC routers in the same backbone fabric should have the same maximum LSAN count defined, to prevent the FC routers from running into indefinite state. Asymmetric LSAN configurations due to different maximum LSAN counts could lead to different devices being imported on different FC routers. To display the current LSAN limit: switch:admin> fcrlsancount LSAN Zone Limit 3000 To set the new LSAN zone limit: switch:admin> fcrlsancount 5000 LSAN Zone Limit 5000 For information on how to display the new maximum LSAN count after it has been changed, see "Monitoring resources" on page 338. NOTE: Since the maximum number of LSANs is configured for each switch, if there is a different maximum LSAN count on the switches throughout the metaSAN, the device import/export will not be identical on the FC routers. Enter the same maximum LSAN count for all the FC routers in the same backbone that supports this feature. Verify the configured maximum limit against the LSANs configured using the fcrresourceShow command. Configuring backbone fabrics for interconnectivity If you want devices in backbone fabrics to communicate with devices in edge fabrics, follow the steps in the section "To set up LSAN zone binding:" on page 335. However, instead of configuring the LSAN in the second edge fabric, configure the LSAN in the backbone fabric. 336 Using the FC-FC routing service
