Sure. You can also use ibstat or ibv_devinfo tool if they are installed. 
But it's not very
convenient in some cases.

E.g.
A customer upgrades FW on HCAs and encounters issues. During triage, 
it's much easier
to study customer uploaded log files when remotely testing different FW 
files.

Thanks.
