[Users] Another ibdiagnet question...

[Ira Weiny]

Does anyone understand the "-i <dev-index>" option?

I have a system with 3 cards in it like this (summary from ibstat)[*]:

mlx4_0 (IB)
	port 1: down
	port 2: up
mlx4_1 (Eth)
	port 1: up
	port 2: down
qib0 (IB)
	port 1: up

The "-i" option to ibdiagnet wants (from the man page):

"the index of the device of the port used to connect to the IB fabric (in case of multiple devices on the local system)"

I don't quite understand what that means.  I _thought_ it would mean that mlx4_0 == 1, mlx4_1 == 2, qib0 ==3.

so I tried:

bash-4.1# ibdiagnet -i 1 -p 2
Loading IBDIAGNET from: /usr/lib64/ibdiagnet1.5.7
-W- Topology file is not specified.
    Reports regarding cluster links will use direct routes.
Loading IBDM from: /usr/lib64/ibdm1.5.7

-E- Device number: 1 does not have port number: 2.
    Exiting.


So perhaps it is zero based?

bash-4.1# ibdiagnet -i 0 -p 2
Loading IBDIAGNET from: /usr/lib64/ibdiagnet1.5.7

-E- Illegal argument: Illegal value for -i option: 0
    (Legal value: a positive integer number).
    Exiting.

SYNOPSYS
  ibdiagnet [-c <count>] [-v] [-r] [-u] [-o <out-dir>]
     [-t <topo-file>] [-s <sys-name>] [-i <dev-index>] [-p <port-num>] [-wt]
     [-pm] [-pc] [-P <<PM>=<Value>>]
     [-lw <1x|4x|12x>] [-ls <2.5|5|10>]
     [-skip <ibdiag check>] [-load_db <db_file>] [-csv] [-vlr]

Nope...  What am I missing?
