Fabric OS v7.1.0a Release Notes v1.0 Page 5 of 41
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.
Note: This warning is not applicable if the current firmware version is not FOS v7.1.0. 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. Please refer to “FOS Migration Considerations” section of this
document for additional considerations.
