VCM not provisioning NIC's correctly

Greetings

I wish to share a problem I am having in the hopes a solution can be found. 

On a freshly imaged VC module, I have attached the uplinks, have created an ethernet network and created a server profile for the BL460c blades in my BladeSystem c7000 g3 Enclosure. Following this, I have booted a previously working Centos 7.6 system, that previously had 2 NIC's available, enumerated as eno49 and 50. 

Upon booting Centos, I am immediately presented with messages such as:

bnx2x - BAD MCP validity signature
bnx2x - FW failed to respond. 
Unregistered net device.... etc


The command "ip a" only shows the lo interface. 

 
Finally, running lshw -c network, shows all controllers but no interaces:

lshw -c network

width: 64 bits

configuration: latency=0


All the way to number 6 unclaimed controllers... On an idential working system, I show network interfaces 0 and 1 only

This is being managed on a VC FlexFabric-20/40 F8 Module (4.80 FW).

Please let me know if I can provide any further information, or if there are any ideas. Thanks!

E-fuse the blade.  Or, if you have physical access to the enclosure, remove the blade and re-insert it.

Re: VCM not provisioning NIC's correctly

Hi,

How many servers are present in the enclosure?

Is this the only server you are facing the issue?

What is the NIC status in the VCM ?

Try unassigned and reassign a new profile.

Try efuse the blade.

Thanks

Re: VCM not provisioning NIC's correctly

Thanks for the replies. Based on your suggestion, I have tripped the e-fuse, but the situation remains the same: the blade is unable to enumerate its networking hardware.

I should mention there are 16 blades in the enclosure and this is affecting 2. I have attempted adding and removing these blades from profiles, tripping the e-fuse, attempting a network boot, and even attempting to install NIC drivers from HPE website (which also fails because card is not detected). I should also mention, booting from ISO of different OS, NIC's are also not detected. 

In the VCM when viewing the networking hardware of the individual blade, the information shown is the same as any working blade in the enclosure:

Re: VCM not provisioning NIC's correctly

Hi,

When you say NIC card is not detected, can you check by swapping the server from this bay to any other bay bay where server is working. If that does not work can you remove swap the NIC card to rule out the hardware issue.

Let me know the outcome.

Thanks
