If you are using the rpm install method, note that after installing the opensm
package, OpenSM is configured to be off after the next machine reboot. It only
needs to be enabled on the node that acts as the subnet manager, so use the
chkconfig command (as a root user) to enable it on the node where it will be
run:
# chkconfig opensmd on
The command to disable it on reboot is:
# chkconfig opensmd off
You can start opensmd without rebooting your machine by typing:
# /etc/init.d/opensmd start
You can stop opensmd again by typing:
# /etc/init.d/opensmd stop
If you want to pass any arguments to the OpenSM program, modify the following
file, and add the arguments to the OPTIONS variable:
/etc/init.d/opensmd
For example:
# Use the UPDN algorithm instead of the Min Hop algorithm.
OPTIONS="-R updn"
For more information on OpenSM, see the OpenSM man pages, or look on the
OpenFabrics web site.
SRP
SRP stands for SCSI RDMA Protocol. It was originally intended to allow the SCSI
protocol to run over InfiniBand for Storage Area Network (SAN) usage. SRP
interfaces directly to the Linux file system through the SRP Upper Layer Protocol
(ULP). SRP storage can be treated as another device.
In this release, two versions of SRP are available: QLogic SRP and OFED SRP.
QLogic SRP is available as part of the QLogicIB-Basic, Rocks Roll, and Platform
OCS downloads. It is not available as a part of the RPM downloads.
SRP has been tested on targets from Engenio™ (now LSI Logic
®
) and DataDirect
Networks™.
NOTE:
Before using SRP, the SRP targets must already be set up by your system
administrator.
