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.
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
®
).
Using QLogic SRP
If you have installed QLogic SRP as part of the QLogicIB-Basic download, you will
need to configure it according to the steps shown in the QLogic ULP and Tools
Reference Guide (OFED+ Users Guide).
Using OFED SRP
To use OFED SRP, follow these steps:
1. Add the line SRP_LOAD=yes to the module list in
/etc/infiniband/openib.conf to have it automatically loaded.
2. Discover the SRP devices on your fabric by running this command (as root):
# ibsrpdm
NOTE:
Before using SRP, the SRP targets must already be set up by your system
administrator.
