Hi Pravein,
Do you happen to have any errors in dmesg output ?
Also, can you post the output of ibdev2netdev ?
Kindest regards,
Raslan Darawsheh

Hi Raslan,
Thanks for your reply.
The lsmod o/p is below :
$ lsmod | grep mlx5_
mlx5_ib 364544 0
ib_uverbs 131072 2 rdma_ucm,mlx5_ib
mlx5_core 1294336 1 mlx5_ib
mlxfw 24576 1 mlx5_core
psample 20480 1 mlx5_core
devlink 45056 1 mlx5_core
ib_core 311296 8 rdma_cm,ib_ipoib,iw_cm,ib_umad,rdma_ucm,ib_uverbs,mlx5_ib,ib_cm
mlx_compat 45056 10 rdma_cm,ib_ipoib,iw_cm,ib_umad,ib_core,rdma_ucm,ib_uverbs,mlx5_ib,ib_cm,mlx5_core

Hi Parvein,
Can you kindly confirm that the kernel drivers (mlx5_ib, mlx5_core) are loaded?
(lsmod | grep mlx5_)
If not please try to restart the kernel driver:
/etc/init.d/openibd force-restart
Kindest regards,
Raslan Darawsheh
