QLogic OFED+ Host Software User Guide, Rev. B

3–TrueScale Cluster Setup and Administration
Managing the TrueScale Driver
Normally, this configuration file is set up correctly at installation and the drivers are
loaded automatically during system boot once the RPMs have been installed.
However, the ib_qib driver has several configuration variables that set reserved
buffers for the software, define events to create trace records, and set the debug
level.
If you are upgrading, your existing configuration files will not be overwritten.
See the ib_qib man page for more details.
Configure the TrueScale 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
NOTE:
This command does not stop and unload the driver if the driver is already
loaded.
Start, Stop, or Restart TrueScale
Restart the software if you install a new QLogic OFED+ Host Software release,
change driver options, or do manual testing.
QLogic recommends using the QLogic IFS Installer TUI to stop, stat and restart
the IPoIB driver. Refer to the QLogic Fabric Software Installation Guide for more
information. For using the command line to stop, start, and restart (as a root user)
the TrueScale support use the following syntex:
# /etc/init.d/openibd [start | stop | restart]
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.
