<tt>Before reboot, I tried following operations</tt><br>
<tt>openibd restart</tt><br>
<tt>network restart</tt><br>
<tt>ibcheckerrors</tt><br>
<tt>ibclearerrors</tt><br>
<br>
<tt>But none of them helped. I had no idea what else I could do. So I tried reboot.</tt><br>
<br>
<tt>If I remember correct, the port state was Linkup before rebooting. And now it</tt><br>
<tt>is active</tt><br>
