Configure InfiniPath 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 root:
$ chkconfig --list openibd
To enable the driver, use the command (as root):
# chkconfig openibd on 2345
To disable the driver on the next system boot, use the command (as root):
# chkconfig openibd off
Start, Stop or Restart InfiniPath
Restart the software if you install a new InfiniPath release, change driver options,
or do manual testing.
You can start, stop, or restart (as root) the InfiniPath support with:
# /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. Note the following:
If OpenSM is configured and running, it must be stopped before the
openibd
stop command, and must be started after the openibd start
command. Omit the commands to start/stop opensmd if you are not running
it on that node.
NOTE:
This command does not stop and unload the driver if the driver is already
loaded.
