fcrLsanCount 2 fcrLsanCount Synopsis Displays or sets the maximum LSAN count. fcrlsancount [max-lsan-count] Description Use this command to set or display the maximum number of LSAN zones that can be configured on the edge fabric. By default, the maximum LSAN count is set to 3000, which is also the minimum. This command lets you create more LSANs on your edge fabric, up to 5000, if needed to support additional devices. The maximum number of supported LSAN devices is 10,000. When executed without operand, this command displays the current LSAN zone limit. This command assumes that all FCRs in the same LSAN fabric matrix or backbone have the same maximum LSAN count defined in order to protect the FCRs from running into indefinite state. Asymmetric LSAN configurations due to different maximum LSAN counts may lead to different devices being imported on different FCRs. Since the maximum number of LSANs is configured per switch, if there is a different maximum LSAN count on the switches throughout the meta-SAN, the device import or export will not be identical on the FCRs. You should therefore 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. Notes The default LSAN count maximum of 3000 is the Fabric OS v5.2 default. It allows v5.2 to run on the standby CP if the active CP runs firmware v5.3 or later. In this case, you cannot increase the LSAN Zone count to 5000, and if the v5.2 standby CP is coming online in a system where the LSAN count is set to 5000, the HA sync will not be established. In addition, downgrading to a firmware version lower than v5.3 is blocked if the LSAN count is set to 5000. 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 This command has the following operands: max-lsan-count Specifies the maximum LSAN count.
