After an upgrade to ESXi 5.5 from ESXi 5.1, all the networking on the host stopped working, as I had already upgraded other BL490c G7 blades with (seemingly) identical hardware but upon upgrading this one the NICS were detected but there was no connectivity through the chassis, the flex-10 to the host. All checks on the BladeSystem controllers and the ESXi OS seemed to show all was working fine and connected, there were no errors on the ports within the BladeSystem. So I attempted the following: https://communities.vmware.com/thread/463557?tstart=0 esxcli system module set --enabled=false --module=elxnet esxcli system module set --enabled=true --module=be2net Reboot host, after a reboot the networking was operational, it appears this is a driver issue within VMware. To revert the changes: esxcli system module set --enabled=false --module=be2net esxcli system module set --enabled=true --module=elxnet Reboot host, networking went back to the failed state again. However this driver was working on (seemingly) identical hardware fine. So I checked the firmware version on a working and not working host: On Host2 (an identical machine to the faulty Host1): # esxcli network nic get -n vmnic0 Advertised Auto Negotiation: true Advertised Link Modes: 10000baseT/Full Auto Negotiation: false Cable Type: Current Message Level: -1 Driver Info: Bus Info: 0000:02:00:0 Driver: elxnet Firmware Version: 4.2.401.6 Version: 10.5.121.7 Link Detected: true Link Status: Up Name: vmnic0 PHYAddress: 0 Pause Autonegotiate: false Pause RX: true Pause TX: true Supported Ports: Supports Auto Negotiation: false Supports Pause: true Supports Wakeon: true Transceiver: Wakeon: MagicPacket(tm)
On Host2 we get: # esxcli network nic get -n vmnic0 Advertised Auto Negotiation: true Advertised Link Modes: 10000baseT/Full Auto Negotiation: false Cable Type: Current Message Level: -1 Driver Info: Bus Info: 0000:02:00:0 Driver: elxnet Firmware Version: 3.102.517.703 Version: 10.5.121.7 Link Detected: true Link Status: Up Name: vmnic0 PHYAddress: 0 Pause Autonegotiate: false Pause RX: true Pause TX: true Supported Ports: Supports Auto Negotiation: false Supports Pause: true Supports Wakeon: true Transceiver: Wakeon: MagicPacket(tm) Notice the firmware on the card if different, this should be upgraded to the same version, that way it resolves the issue. Upgraded the NIC firmware, rebooted the host afterwards the networking operated as expected. http://h20564.www2.hpe.com/hpsc/swd/public/readIndex?sp4ts.oid=4194638&swLangOid=8&swEnvOid=54 |
