[openib-general] Re: [OpenSM] SA database query tool

[Eitan Zahavi]

Hi James,

Assuming you ask for a remote access to the data through the IB network
(In-Band):
(but actually this will work also in loopback if run on the same IB port)

If you need the query tool for scripting ibis is your best choice.

A quick example for what you need to do to get all NodeInfoRecor's:

ibis -port_num 1 
sacNodeQuery getTable 0 # the zero is the comp mask.

You could also read the ibis.c and the osm_vendor_sa_api.h to see how one
can implement that in C.

You could use umad directly 

Or decide to re-write the exiting software too.
