Can not create srpt entry with targetcli in Rocky 8.5

Rocky Linux General

I have a Rocky 8.5 system with an Infiniband HCA and when I try to create a srpt entry with targetcli I get the error
/srpt> create 0xfe8000000000000008c0eb0300e36a72
Could not create SRPTFabricModule in configFS

The HCA

ibstatus

Infiniband device ‘mlx5_0’ port 1 status:

/srpt> create ib.fe8000000000000008c0eb0300e36a72

Any suggestion?

On CentOS 7.x9 the procedure works fine. I have seen that the RDMA configuration in RH/Roocky 8.4 onward is different from CentOS 7.9 but the ib_srpt kernel module seems is active

lsmod| grep srpt

ib_srpt 16384 0
mlx_compat 16384 12 rdma_cm,ib_ipoib,mlxdevm,ib_srpt,iw_cm,ib_umad,ib_core,rdma_ucm,ib_uverbs,mlx5_ib,ib_cm,mlx5_core

I understand now that on the node is installed OFED package MLNXOFEDv55103 and in the documentation
https://docs.nvidia.com/networking/display/MLNXOFEDv551032/SRP+-+SCSI+RDMA+Protocol
is reported
“This package, however, does not include an SRP Target.”
I will try on other “vanilla” Rocky system to see if it works and I will report.
