1. The S5100 is connected to a megabit switch. The network ports on the switch are correctly mapped to the service network ports on the S5100. 2. A number of error codes can be detected by logging in to the OSM and then choosing Performance > iSCSI Error Codes after services are started on the S5100.
Step 1 Execute the ethtool command to forcibly set the operating mode to the full-duplex mode. Step 2 Execute the debug bash command to access the background. Step 3 Execute the ethtool -s eth? autoneg off command. Step 4 Execute the ethtool -s eth? duplex full command.
1. The service network ports on the S5100 and the network ports on the switch are not uniquely mapped. Moreover, error codes persist even after these ports are uniquely mapped. Therefore, the problem is irrelevant to the link between both devices. 2. R&D engineers find that the rates and working modes of the S5100 and the megabit switch are inconsistent. Specifically, the S5100 network adapter works at the rate of 100 Mbit/s in half-duplex mode, while the megabit switch works at the rate of 100 Mbit/s in full-duplex mode.
If a GE network is required later on, you can execute the ethtool -s speed 1000 command to forcibly set the switch rate to 1000 Mbit/s.
