Fabric OS v6.4.3f Release Notes v1.0 Page 108 of 149
Defect ID: DEFECT000322883
Technical Severity: High
Summary: Brocade 48000 running FOS v6.2.0x are unable to upgrade to v6.3.x when a GE port is
present and is persistently disabled.
Symptom: After a firmware download from FOS 6.2 to FOS 6.3, active CP may fail to come online
completely. After rebooting CP to recover, if CP is downgraded to FOS v6.2 code again, the
CP is left with an invalid configuration. The invalid configuration prevents the CP from
successfully upgrading again. A good CP with a valid configuration could be affected by the
misconfigured CP if it is HA synced with this CP. This applies to FR4-18i only.
Workaround: Enable all persistently disabled GE port prior to the first upgrade. If a downgrade is
performed already, configuremove the configuration and download a valid configuration
to restore the CP.
