I had 2 iSeries (AS/400s) in the same data center which were connected via Ethernet, and at the same time supported SNA communications between the 2 systems. This supports QSNADS file distribution between the 2 systems. This was configured and working successfully in the same datacenter, but when 1 of the machines was relocated to a datacenter in a remote building, the appc controllers and respective appc devices (representing the 2 systems) cannot be varied on to support the SNA connectivity. They stay on a 'vary on pending' status. The AS/400 in the remote location had a change with it's IP and default route. while the host table entry for the local system had it's IP entry for the remote system changed accordingly; Ethernet connectivity between the 2 systems is successful. It's just the appc / sna connectivity that got clobbered, What did I miss?
