Possibly OT: How to diagnose 3494 ATL "communications" failures
2004-05-20 09:15:57
Recently, my TSM AIX server has been reporting issues "communicating" with
our 3494 ATL (plain jane....no VTS). This is not a new connection. Has
been working for years.
TSM has started to notice the issues.
I contacted IBM, who says they couldn't find anything wrong. We checked
the network cable, end-to-end, with no media issues.
The AIX /var/adm/messages show:
