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<\/p>\n\n\n\n
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<\/p>\n\n\n\n
BladeSystem.<\/p>\n\n\n\n
So I attempted the following:<\/p>\n\n\n\n

However this driver was working on (seemingly) identical hardware fine. So I checked the firmware version on a working and not working host:<\/p>\n\n\n\n On Host2 (an identical machine to the faulty Host1):<\/p>\n\n\n\n # esxcli network nic get -n vmnic0<\/p>\n\n\n\n Advertised Auto Negotiation: true<\/p>\n\n\n\n Advertised Link Modes: 10000baseT\/Full<\/p>\n\n\n\n Auto Negotiation: false<\/p>\n\n\n\n Cable Type:<\/p>\n\n\n\n Current Message Level: -1<\/p>\n\n\n\n Driver Info:<\/p>\n\n\n\n Bus Info: 0000:02:00:0<\/p>\n\n\n\n Driver: elxnet<\/p>\n\n\n\n Firmware Version: 4.2.401.6<\/p>\n\n\n\n Version: 10.5.121.7<\/p>\n\n\n\n Link Detected: true<\/p>\n\n\n\n Link Status: Up<\/p>\n\n\n\n Name: vmnic0<\/p>\n\n\n\n PHYAddress: 0<\/p>\n\n\n\n Pause Autonegotiate: false<\/p>\n\n\n\n Pause RX: true<\/p>\n\n\n\n Pause TX: true<\/p>\n\n\n\n Supported Ports:<\/p>\n\n\n\n Supports Auto Negotiation: false<\/p>\n\n\n\n Supports Pause: true<\/p>\n\n\n\n Supports Wakeon: true<\/p>\n\n\n\n Transceiver:<\/p>\n\n\n\n Wakeon: MagicPacket(tm)<\/p>\n\n\n\n On Host2 we get:<\/p>\n\n\n\n # esxcli network nic get -n vmnic0<\/p>\n\n\n\n Advertised Auto Negotiation: true<\/p>\n\n\n\n Advertised Link Modes: 10000baseT\/Full<\/p>\n\n\n\n Auto Negotiation: false<\/p>\n\n\n\n Cable Type:<\/p>\n\n\n\n Current Message Level: -1<\/p>\n\n\n\n Driver Info:<\/p>\n\n\n\n Bus Info: 0000:02:00:0<\/p>\n\n\n\n Driver: elxnet<\/p>\n\n\n\n Firmware Version: 3.102.517.703<\/p>\n\n\n\n Version: 10.5.121.7<\/p>\n\n\n\n Link Detected: true<\/p>\n\n\n\n Link Status: Up<\/p>\n\n\n\n Name: vmnic0<\/p>\n\n\n\n PHYAddress: 0<\/p>\n\n\n\n Pause Autonegotiate: false<\/p>\n\n\n\n Pause RX: true<\/p>\n\n\n\n Pause TX: true<\/p>\n\n\n\n Supported Ports:<\/p>\n\n\n\n Supports Auto Negotiation: false<\/p>\n\n\n\n Supports Pause: true<\/p>\n\n\n\n Supports Wakeon: true<\/p>\n\n\n\n Transceiver:<\/p>\n\n\n\n Wakeon: MagicPacket(tm)<\/p>\n\n\n\n Notice the firmware on the card if different, this should be upgraded to the same version, that way it resolves the issue.<\/p>\n\n\n\n Upgraded the NIC firmware, rebooted the host afterwards the networking operated as expected.<\/p>\n\n\n\n http:\/\/h20564.www2.hpe.com\/hpsc\/swd\/public\/readIndex?sp4ts.oid=4194638&swLangOid=8&swEnvOid=54<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" 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.
