At first I thought you were responding to a thread of last week but it's the wrong newsgroup. Perhaps you would like to post this again on the IBMTCP-L newsgroup as another "experience" under "OSA ARP Takeover - experiences". According to the redbook, you need just "pull the cable". According to my dimly remembered experience, the technician simply logically disabled the interface from the management software running on his PC.
