Hi there,<BR>
<BR>
I suppose I should ask all the obvious questions, like:<BR>
<BR>
</SPAN></FONT><UL><LI><FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>does your IB card have an IP address assigned to it?
</SPAN></FONT><LI><FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>does it have the right netmask configured for the address?
</SPAN></FONT><LI><FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>do the other machines on the IB network also have addresses on them with the correct netmasks?
</SPAN></FONT><LI><FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>have you tested TCP/IP on any other hosts in your cluster and confirmed that it is working as expected?<BR>
</SPAN></FONT></UL><FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'><BR>
I don’t have a lot of experience with broken IB cards, but they’re just as subject to IP misconfiguration as Ethernet can be ... I don’t recall offhand if there are hardware layer diagnostics for the (I’m assuming Voltaire) card itself, but there probably are, and they could help you verify physical connectivity. However, assuming your IP configuration is both valid and usable, if it’s still inoperable, then you probably have a bad card. Have you tried the other IB port (if the card has more than one), or swapping another IB card from another host that you know to be working?<BR>

I ran the vstat command and found one of the port_state is 'port_initialize'.<BR>
What does 'port_initialize' mean? Dose it mean my ib card is broken?<BR>
