Do you mean "replace"? Are you going to replace the adapter with the same type? Just make sure that after the change the adapter device name (ent0, en0) and the IP-address is the same as before. So don't rmdev -dl the device if it is the same type (don't flush the adapter's CuAt information).
HACMP is nice when you want to exchange hardware as the service can be running on another node while the repair is going on. You can start HACMP on the repaired node and fallback the resource group after the new device is configured as its predecessor was.
