    Replacing NICs

    radio_müsli Novice

      Hi All


      We need to replace faulty NICs (same Type into same Slot) on our ESX Servers. I've done this on one machine and after starting up one VM everythings seems to work fine. However I noticed that the MAC adresses in esx.conf did not change and still show the values of the replaced (old) NIC:



      net/pnic/child0002/duplex = "auto"

      /net/pnic/child0002/mac = "00:18:fe:2e:51:1d"

      /net/pnic/child0002/name = "vmnic2"

      /net/pnic/child0002/speed = "auto"

      /net/pnic/child0002/virtualMac = "00:50:56:5e:51:1d"



      ifconfig shows the MAC adress as: vmnic2 Link encap:Ethernet HWaddr 00:1F:29:0D:AC:71 which is correct for the new NIC


      I ran the following commands


      • /usr/sbin/esxcfg-boot -p

      • /usr/sbin/esxcfg-boot -b

      • /usr/sbin/esxcfg-boot -rg


      and rebooted the server, however esx.conf still shows the old values. Anyone have an idea?

          Got this reply from VMware Tech Support:  >>Engineering confirmed the entry recorded on esx.conf is taken on the install/config proccess and afterwards the software never makes use of that entry again, so everything should be fine for you. In any case you could manually change the esx.conf file for cosmetic reasons but that won't make a difference in your normal operations.<< There's nothing to do
