A
Using QLogic SRP
If you installed QLogic SRP as part of the QLogicIB-Basic download, 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 a root
user):
# ibsrpdm
In the output, look for lines similar to these:
GUID: 0002c90200402c04
ID: LSI Storage Systems SRP Driver 200400a0b8114527
service entries: 1
service[ 0]: 200400a0b8114527 / SRP.T10:200400A0B8114527
GUID: 0002c90200402c0c

ID: Data Direct Networks SRP Target System
service entries: 1
service[ 0]: f60b04ff01000021 / SRP.T10:21000001ff040bf6
Note that not all the output is shown here; key elements are expected to
show the match in Step 3.
