HP BL490c G7 Blade within a c7000 BladeSystem Chassis with Flex-10 Networking Fails after ESXi 5.5 Upgrade

posted 22 Aug 2016, 12:05 by Tristan Self

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.
