Hi
I 'm a french AIX user
In a 7026-H70 machine, with 2 2-port multiprotocol PCI adapters
one PCI adapter works well and the other not

lsx25 shows

sx25a0 and sx25a1 works well but not sx25a2

Question :
1) Why lsx25 says num_port = 4 et num_port = 5 and not 2 and 3 ? Can I
change it ?
2) I think it's an hardware problem, what diag can i use ?

Regards

I seem to recall that the AIXLink/X.25 code (lslpp -h 'xs25.*')
had different licensing levels.  Maybe you have the level
installed that allows 2 virtual circuits but you need the
next level which allows 8 or unlimited.  It had something
to do with whether sx25.server was installed or just sx25.rte.

I think these values are assigned in the order in which the
sx25aX virtual ports are defined on top of the hdlcY real ports.
Note that X and Y don't have to be the same, but they usually are.
To see the mapping, do:
  lsattr -E -l sx25a0 | grep hdlc
Maybe you had a third card in this box at one time,
or someone defined multiple sx25aX on an hdlcY

Quote:> Can I change it?

Yes, but it would require deleting all the existing
definitions and readding them in a logical order.

Quote:> 2) I think it's an hardware problem, what diag can i use ?

I use the 'diag' command from within aix on these cards.
There are two levels:
  Diagnostics Routines
  Advanced Diagnostics Routines
Both require that whatever s/w is using the ports be brought
down (so the diags have complete control of that card).
The Advanced Diagnostics needs a small wrap plug that
should have come with the card, but is easily misplaced.
There are tests for the card 'dpmpa0' and the ports 'hdlcX'.
This all requires that you have this lpp installed:
  devices.pci.331121b9.diag
You can also run the standalone diagnostics
(boot from the diagnostics CD).

Have you run:
  hdlcstat hdlcX
where X is 0,1,2,3.  Do all the ports say they see the cable
installed? The cables are these cards are easy to un-seat.
