Overview Fabric OS (FOS) v7.1.0a is a patch release based on FOS v7.1.0. All hardware platforms and features supported in FOS v7.1.0 are also supported in FOS v7.1.0a. Warning - Applicable only if upgrading from FOS v7.1.0: Before upgrading the firmware to FOS v7.1.0a from FOS v7.1.0, you must run the supportSave command to save any existing error log information. Once the switch is upgraded to FOS v7.1.0a, any previously existing error log entries on the switch will be permanently lost - only new error log entries created while running FOS v7.1.0a will be retained.

For example, if the upgrade is being performed from FOS v7.0.x or FOS v6.4.x to FOS v7.1.0a, the existing error log entries will be preserved even after upgrading to FOS v7.1.0a.
