See the
ib_qib
man page for more details.
Configure the ib_qib Driver State
Use the following commands to check or configure the state. These methods will
not reboot the system.
To check the configuration state, use this command. You do not need to be a root
user:
$ chkconfig --list openibd
To enable the driver, use the following command (as a root user):
# chkconfig openibd on 2345
To disable the driver on the next system boot, use the following command (as a
root user):
# chkconfig openibd off
Start, Stop, or Restart ib_qib Driver
Restart the software if you install a new QLogic OFED+ Host Software release,
change driver options, or do manual testing.
QLogic recommends using
/etc/init.d/openibd
to stop, stat and restart the
ib_qib driver. For using the command line to stop, start, and restart (as a root user)
the ib_qib driver use the following syntex:
# /etc/init.d/openibd [start | stop | restart]
This method will not reboot the system. The following set of commands shows
how to use this script.
When you need to determine which ib_qib driver and OpenFabrics modules are
running, use the following command. You do not need to be a root user.
$ lsmod | egrep ’ipath_|ib_|rdma_|findex’
NOTE
This command does not stop and unload the driver if the driver is already
loaded nor will it start the driver.
!
WARNING
If QLogic Fabric Manager, or OpenSM is configured and running on the
node, it must be stopped before using the
openibd
stop
command, and
may be started after using the
openibd start
command.
