Linux, RHEL taking away a network device

(This is a different situation than my previous posts

I am using RHEL 6.4

I have to take away a ethernet device (specifically a VMWare CPI dev 0, passthrough)

My intention is to disconnect this already configured device and replace it with another working adapter

Should I

remove the current ifcfg-eth3 file before I remove the device

If so, how should I do this ?

Thanks

It is up to you.

You can simply move it to OLD for reference

mv /etc/sysconfig/network-scripts/ifcfg-eth3  /etc/sysconfig/network-scripts/OLD-ifcfg-eth3
ifdown eth3

Open in new window


Second command would take it down (off line).

Should I do this before or after I power down the VM and remove the device, or does it matter

It shouldn't matter.
