Restarting InfiniPath
When the driver status appears abnormal on any node, you can try restarting (as
a root user). Type:
# /etc/init.d/openibd restart
These two commands perform the same function as restart:
# /etc/init.d/openibd stop
# /etc/init.d/openibd start
Also check the /var/log/messages file for any abnormal activity.
