Infiniband port status UP but can't open UMAD port ((null):0)

My system has 2 infiniband devices, one of which has both the ports up.

$> ibstatus
  Infiniband device 'mlx4_0' port 1 status:

  Infiniband device 'mlx4_1' port 2 status:
          default gid:     fe80:0000:0000:0000:0002:c903:000f:0a6c

Now, when I check the ib port state by lid,

 $> ibportstate  -L 10x22 enable
 ibwarn: [14836] mad_rpc_open_port: can't open UMAD port ((null):0)
 ibportstate: iberror: failed: Failed to open '(null)' port '0'

I am not sure about the reason for this error message. Am I missing something?

Does the corresponding umad device file exist (this is typically /dev/infiniband/umad0) ?

Also, on the system I have access to, permissions of /dev/infiniband/umad0 are set by default such that normal users can't access them:

crw-rw---- 1 root root 231, 0 Feb  1 16:00 /dev/infiniband/umad0

so you could use sudo to run your command (or relax the permissions of /dev/infiniband/umad0).

It maybe just a typo here on SO, but you are specifying LID as 10x22. As LID is supposed to be a hexadecimal number, the 1 is extraneous. It should be just a 0x22.
