Hi Guys,

I’m just running into a strange problem, I try to through SRP to a target and can find the target by ibhosts and ibsrpdm. but when I run command like below to add target on initiator, it crashes the system immediately(system reboot)

echo

-n max_cmd_per_lun=256,id_ext=0002c903005836ae,ioc_guid=0002c903005836ae,dgid=fe800000000000000002c903005836af,pkey=ffff,service_id=0002c903005836ae,initiator_ext=0x0002c90300583b53

>/sys/class/infiniband_srp/srp-mlx4_0-1/add_target

the target works well with intiator on MLNX_OFED-2.0, but this problem occurs on MLNX_OFED-1.5.3, anyone has met this issue before or has any suggestion? thanks a lot.

Environment:

Initiator:

SLES 11 SP2, MLNX_OFED-1.5.3-3.0.0, firmware

2.9.1/2.11(two HCAs on initiator, no bonding, tried replace firmware but

didn’t help)

Target:

Mellanox ConnectX-3 HCA, target and initiator connect

through switch.

Just to let you know that only SRP-Initiator is included in MLNX_OFED for Linux (1.5.3 & 2.0), which is actually based on open source from OpenFabrics, however, this package does not include an SRP Target. It’s within the storage-vendor provider’s responsibility to supply, support and ensure SRP target is fully

compatible with OpenFabrics. This may explain the problem you encountered.
