CS/AIX LU0 Primary on 2-Port Multiprotocol Adapter

CS/AIX LU0 Primary on 2-Port Multiprotocol Adapter

Post by M. Davi » Thu, 29 Oct 1998 04:00:00


I've hit a dead-end trying to configure a LU0 Primary line under
CS/AIX 5.  This is on a F40 running 4.3.  What's new to me is the
2-Port Multiprotocol PCI Adapter.

IBM refers to this as a "shallow" adapter - one with no onboard
co-processor.  It uses a hdlc driver instead of tw.  And for some
reason smit doesn't show a 'manage ports' option for it.  I can't get
any device for it to show up in /dev (ie: /dev/mpqd0).  The lu0server
program is looking for a valid device, and failing with errno=2 when I
try things like hdlc0.

Link/X.25 documentation has a specifc appendix to address differences
in the 2-Port.  I've drawn a blank in CS/AIX docs.  Is this adapter

Thanks for any and all help,
