Hi,

We have to change some of our network card on our hyperscale x appliance.We want to know if we have to  use the procedure for refreshing hyperscale x appliance nodes just to reconfigure network or is there any other ways ?

Regards

Hi @nhaing 

The only thing that will be need to done manually in case network interface name. With the new card the MAC and interface name is likely to change. 

ifcfg files created for the interfaces will be ineffective if the network name doesn’t match.

Try the steps and see if it helps:

  • Verify the names and MAC address of the current interfaces by running ip link and ip a.
  • Remove the existing card and insert new cards. Run the ip link command to find the new interface names and MAC address.
  • Edit the file /etc/udev/rules.d/70-persistent-net.rules which would look like below. Put the MAC address to the corresponding interface.
    ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{type}=="1", ATTR{address}=="3c🇪🇨ef:1a:cc:8a", NAME="enpsf1"
    ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{type}=="1", ATTR{address}=="3c🇪🇨ef:1a:cc:8b", NAME="enpsf2"
    ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{type}=="1", ATTR{address}=="3c🇪🇨ef:3d:ea:98", NAME="enpsf3"
    ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{type}=="1", ATTR{address}=="3c🇪🇨ef:3d:ea:99", NAME="enpsf4"
    ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{type}=="1", ATTR{address}=="3c🇪🇨ef:3d:ea:d0", NAME="enpsf5"
    ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{type}=="1", ATTR{address}=="3c🇪🇨ef:3d:ea:d1", NAME="enpsf6"
  • Ensure that the physical layout is appropriate on the switch side for any LACP side config.
