We set them both to 1 as show below. We now get a configuration error DTCCTC059 (TCP/IP recognizes link adapter address is invalid.) We set them back to 0 and 1 and we can get the links up again. Netstat Devlinks show both sides Ready with no error status. Netstat Gate show the route with flags UHS. As soon as we ping from one side or the other we get the Unit Check. Netstat Devlinks show bytes out going up but nothing on bytes in. Side being pinged now show error status on Netstat Devlinks Ron >lpar one >---------- >attach 448 tcpip 720 >attach 449 tcpip 721 > >lpar two >---------- >attach 508 tcpip 720 >attach 509 tcpip 721 > >> >; lpar one tcp/ip device/link >DEVICE CTCVDEV4 CTC 720 >LINK CTCVLNK4 CTC 1 CTCVDEV4 > >; lpar two tcp/ip device/link >DEVICE CTCVDEV4 CTC 0720 >LINK CTCVLNK4 CTC 1 CTCVDEV4 MTU 1500 > > >
