fcrlsanmatrix --fabricview The following is an example: FCR:Admin > fcrlsanmatrix --fabricview LSAN MATRIX is activated Fabric ID 1 Fabric ID 2 4 5 4 7 10 19 Default LSAN Matrix: 1 2 8 See the Fabric OS Command Reference Manual for additional information on the fcrlsanmatrix command. Dual backbone configuration When dual backbones share edge fabrics, one of the backbone is selected to be the owner of the edge fabric which sends device state updates to the other backbone through the shared edge fabric. With 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 portdisable/enable. Maximum LSAN count The fcrlsancount command lets you configure the maximum number of LSANs, or LSAN count, that can be configured on the edge fabric, which is up to 5000 without disabling the switch. By default, the maximum LSAN count is set to 3000. This command lets you create more LSANs on your edge fabric where needed. The maximum devices supported is still 10000. This command is also supported in Secure Fabric OS. The fcrlsancount command assumes that all the FCRs in the same LSAN fabric matrix or backbone have the same maximum number of LSAN count defined, to protect all the FCRs from running into indefinite state. Asymmetric LSAN configurations due to different maximum LSAN counts could lead to different devices being imported on different FCRs. The following example shows the use of the fcrlsancount command that allows you to display the current LSAN limit or to set the maximum LSAN Zone count: 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, page 256. Since the maximum number of LSANs is configured per switch, if there is a different maximum LSAN count on the switches throughout the metaSAN, then the device import/export will not be identical on the FCRs. You should enter the same maximum LSAN count for all the FCR switches in the same backbone that support this feature. Verify the configured maximum limit against the LSANs configured using the fcrresourceshow command. Fabric OS 5.3.0 administrator guide 249
