Info
The 32G QSFP optic which is sold as HPE SKU Q2R28A, Q2R29A, Q2R30A, or FRU 881754-001 with label part number 57-1000351-XX may fail to come online after ports are bounced from actions such as: loss of light, port disable then port enable, or cable pulls. After upgrading from an earlier version of HPE B-Series Fabric OS (FOS) to HPE B-Series FOS 8.1.2b, any port that contains this specific 32G QSFP optic will continue to run without issue until the port is bounced. After the port is bounced, if not running in a known working configuration as shown below, the port will fail to come back online. There is no issue with other 32G QSFP part numbers or with other firmware versions. Working Configurations The 32G QSFP is not at risk of failure in the following ICL configurations between a pair of directors in FOS v8.1.2b: Director A ICL Connection Director B Platform Optic Port Speed* Platform Optic Port Speed* HPE StoreFabric SN8600B Director Switch ZUA ASN HPE StoreFabric SN8600B Director Switch ZUA ASN ZUA ASN ZTA ASN ZUA ASN ZTA 32G ZUA = 32G QSFP (label P/N 57-1000351-XX sold as HPE SKU Q2R28A, Q2R29A, Q2R30A, or FRU 881754-001) ZTA = 32G QSFP (label P/N 57-1000331-XX sold as HPE SKU Q0U62A, Q0U91A, Q0U89A, or FRU 871363-001) NOTE : Unique to core (CR) blades on directors, switchShow command output always indicates the operating Port Speed configured on a switch port. PortCfgShow always shows the configured Port Speed on the switch port. Only on core blades, when the configured Port Speed is set to the default "AUTO" (Auto-Negotiate or ASN) speed, switchShow displays the switch port's highest-capable speed. On the X6 director, the switchShow output is 32G. So, when comparing a switch configuration to the above table, it is paramount to look at the configured Port Speed using portCfgShow but not the switchShow output (or the equivalent in other management interfaces). At-risk configurations All other configuration not shown in the above table on the HPE StoreFabric SN8600B Director Switch are "at-risk" and all configurations on the HPE StoreFabric SN6600B SAN Switch are "at-risk". When this issue is experienced, the port with a 32G break-out QSFP optic installed will come up as being in an "In-Sync" or "No-Sync" state.
Scope
To be at risk for this failure, all of the following conditions must be present: The platform model must be an HPE StoreFabric SN8600B Director Switch or HPE StoreFabric SN6600B SAN Switch. The switch must be using a specific 32G QSFP (sold as HPE SKU Q2R28A, Q2R29A, Q2R30A, or FRU 881754-001 with label part number 57-1000351-XX). Other 32G QSFP types are not affected. The switch must be running HPE B-Series FOS 8.1.2b The switch must be operating in an "at-risk" configuration
Resolution
HPE recommends upgrading to HPE B-Series FOS 8.1.2d or later firmware. Any at-risk configuration with 32G break-out QSFP optics sold as HPE SKU Q2R28A, Q2R29A, Q2R30A, or FRU 881754-001 with label part number 57-1000351-XX should remain on HPE B-Series FOS 8.1.2a or earlier versions until the customer is ready to upgrade the configuration to HPE B-Series FOS 8.1.2d (or later) or HPE B-Series FOS 8.2.0a (or later) firmware. Workaround Once the 32G break-out QSFP fails to come online, the only way to recover is to upgrade firmware to a version that contains the fix. Temporary port recovery is only possible by power-cycling the switch; however, the port is again vulnerable to the link failure following another bounce.
