gm_board_info only shows the node itself

Hi,

I've got a problem that GM mapper only sees the node itself, and doesn't 
communicate each other.
I appreciate if anybody has a clue/suggestion to this... Thank you in 
advance !

I am currently using GM 2.0.6 and Myrinet "B" card with serial cable.
I have two nodes(hpc001/hpc002) with Linux 2.4.18-3bigmem(RedHat7.3) 
installed.
I know the combination of driver/card is not the good one, but this is a 
test environment for some software.

I noticed that I couldn't use MPICH-GM properly, and this was probably 
because of driver layer.
gm_board_info only shows the node itself, and doesn't show the another 
node.
I did this several times, but the situation remains the same.
service gm stop
service gm start

Also, I changed the physical port(of the switch), but it didn't solve the 
problem.

The odd thing is that I could use the environment without any problem for 
several days.
I tested the MPICH-GM with its sample program, cpi, and saw it works 
without problem.
I left the machines for a couple of days and then returned, and saw this 
has happend.

Does anyone have any idea or suggestion, at least how to diag this ?

These are the output of gm_board_info on the each nodes.
