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

NOTE:

This command does not stop and unload the driver if the driver is already loaded.

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.
