Description:
Info
Due to a regression in Fabric OS (FOS) v7.4.2b, a switch may experience port bounces during a firmware upgrade to FOS v7.4.2b, or during warm recovery events such as a high availability fail-over (hafailover) or high availability reboot (hareboot). This regression only exists in FOS v7.4.2b. No other FOS releases are affected by this issue. If a switch is running a lower FOS version do not upgrade to FOS v7.4.2b. If any ports bounce when upgrading to FOS v7.4.2b, then the same port bounce events will be observed on any future warm recovery (hafailover, hareboot) while running FOS v7.4.2b. If ports do not bounce when upgrading to FOS v7.4.2b, then the switch will be at risk for port bounce events on a future warm recovery under the following known conditions: On non-virtual fabric mode switches with shared area ports, any device or port change that transitions the shared area ports from F_port to non-F_port before the warm recovery On virtual fabric mode enabled switches on a logical switch that is not the default or base switch where two or more distinct paths exist with inter-Chassis links (ICL), inter-switch links (ISL), or inter-fabric links (IFL) between the logical switch and its neighbor In the case of switch warm recovery, FOS raslog will capture logging of C3-1037 and/or C3-1041 (or C3-1042), or C2-1037 and/or C2-1034 (or C2-1035) warning messages at the time of the port bounces. NOTE: For ports that do not bounce when upgrading to FOS v7.4.2b and are beyond the above known conditions, the potential risk of port bounce during warm recovery events is small but cannot be completely eliminated. Upgrading from FOS v7.4.2b to FOS v7.4.2c is not affected by this issue.
Scope
The following platforms running or being upgraded to FOS v7.4.2b are affected by this issue: HPE SN8000B 8-Slot Backbone Director Switch HPE SN8000B 4-Slot SAN Director Switch HPE DC SAN Backbone Director Switch HPE DC04 SAN Director Switch HPE 1606 Extension SAN Switch HPE 8/40 SAN Switch HPE 8/80 SAN Switch HPE StoreFabric SN4000B SAN Extension Switch HPE StoreFabric SN6000B Fibre Channel Switch HPE StoreFabric SN6500B Fibre Channel Switch
Resolution
Hewlett Packard Enterprise recommends upgrading to FOS v7.4.2c. FOS v7.4.2b was removed from the HPE Support Center to prevent customers from encountering this issue during a firmware upgrade. For customers who have planned to upgrade their switches to FOS v7.4.2b to address: https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-a00039785en_us HPE now recommends an upgrade to FOS v7.4.2c instead. For switches that are already running FOS v7.4.2b without encountering port bounces, there is no immediate need to upgrade. HPE recommends upgrading to FOS v7.4.2c at your earliest convenience.
