If you’re using IPoIB, you can use standard TCP/IP diagnostic tools the same way you would on an Ethernet link (ifconfig, ping, traceroute, telnet, etc.)<BR>
<BR>
If you’re using a copper-to-optical converter in your data path as well, the Emcore MIAs have link lights on them which will tell you if a physical link is present (check the documentation). I know with STP InfiniBand connectors, there is some ambiguity about terminology with some vendors and manufacturers, and the fibre arrangement doesn’t provide a lot of wiggle room.<BR>

<BR>
It meant that viblnd couldn't find a port whose link state was active <BR>
on the hca InfiniHost_III_Ex0, i.e. no link on the device was usable.<BR>
<BR>
Was there any other error messages from viblnd before this one? <BR>
</SPAN></FONT></BLOCKQUOTE><FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>There was no error messages but a related message <BR>
like 'ADDRCONF(NETDEV_UP):ipoib0: link is not ready'.<BR>

How can I check the link on the device? Thanks in advance.<BR>
