VMware vNIC placement order not adhered to Cisco UCS configuration – How to fix it?

It is better to use Cisco UCS Consistent Device Naming CDN + ESXi 6.7, but in same casses. It is necessary fix manualy according KB – How VMware ESXi determines the order in which names are assigned to devices (2091560) .

Here is an example How to fix it:

Check current mapping

[~] esxcfg-nics -l
 Name    PCI           MAC Address       
 vmnic0  0000:67:00.0  00:25:b5:00:a0:0e 
 vmnic1  0000:67:00.1  00:25:b5:00:b2:2f 
 vmnic2  0000:62:00.0  00:25:b5:00:a0:2e 
 vmnic3  0000:62:00.1  00:25:b5:00:b2:4f 
 vmnic4  0000:62:00.2  00:25:b5:00:a0:3e 

[~] localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal alias list
 Bus type  Bus address            Alias
 pci       s00000002:03.02        vmnic4
 pci       s00000002:03.01        vmnic3
 pci       s0000000b:03.00        vmnic0
 pci       s0000000b:03.01        vmnic1
 pci       p0000:00:11.5          vmhba0
 pci       s00000002:03.00        vmnic2
 logical   pci#s0000000b:03.00#0  vmnic0
 logical   pci#s0000000b:03.01#0  vmnic1
 logical   pci#s00000002:03.01#0  vmnic3
 logical   pci#s00000002:03.02#0  vmnic4
 logical   pci#p0000:00:11.5#0    vmhba0
 logical   pci#s00000002:03.00#0  vmnic2

Fix transfer table for physical devices

Bus type  Bus address            Alias
 pci       s0000000b:03.00        vmnic0 --> vmnic3
 pci       s0000000b:03.01        vmnic1 --> vmnic4
 pci       s00000002:03.00        vmnic2 --> vmnic0
 pci       s00000002:03.01        vmnic3 --> vmnic1
 pci       s00000002:03.02        vmnic4 --> vmnic2

Fix commands for physical devices

localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal alias store --alias vmnic0 --bus-address s00000002:03.00 --bus-type pci

 localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal alias store --alias vmnic1 --bus-address s00000002:03.01 --bus-type pci

 localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal alias store --alias vmnic2 --bus-address s00000002:03.02 --bus-type pci

 localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal alias store --alias vmnic3 --bus-address s0000000b:03.00 --bus-type pci

 localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal alias store --alias vmnic4 --bus-address s0000000b:03.01 --bus-type pci

Fix transfer table for logical devices

[~] localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal alias list
 Bus type  Bus address            Alias
 logical   pci#s0000000b:03.00#0  vmnic0 --> vmnic3
 logical   pci#s0000000b:03.01#0  vmnic1 --> vmnic4
 logical   pci#s00000002:03.00#0  vmnic2 --> vmnic0
 logical   pci#s00000002:03.01#0  vmnic3 --> vmnic1
 logical   pci#s00000002:03.02#0  vmnic4 --> vmnic2

Fix commands for logical devices

localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal alias store --alias vmnic0 --bus-address pci#s00000002:03.00#0 --bus-type logical

localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal alias store --alias vmnic1 --bus-address pci#s00000002:03.01#0 --bus-type logical

localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal alias store --alias vmnic2 --bus-address pci#s00000002:03.02#0 --bus-type logical

localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal alias store --alias vmnic3 --bus-address pci#s0000000b:03.00#0 --bus-type logical

localcli --plugin-dir /usr/lib/vmware/esxcli/int/ deviceInternal alias store --alias vmnic4 --bus-address pci#s0000000b:03.01#0 --bus-type logical

Reboot

reboot

Crosscheck – Now we have target order

[~] esxcfg-nics -l
 Name    PCI           MAC Address       
 vmnic0  0000:62:00.0  00:25:b5:00:a0:2e 
 vmnic1  0000:62:00.1  00:25:b5:00:b2:4f 
 vmnic2  0000:62:00.2  00:25:b5:00:a0:3e 
 vmnic3  0000:67:00.0  00:25:b5:00:a0:0e 
 vmnic4  0000:67:00.1  00:25:b5:00:b2:2f
