G'day all,
I'm stumped. I just applied SP1 to a working SLES9 system, and after the
IPL my Guest LAN connection now appears to be non-functional. I've checked
all the obvious things but so far I'm none the wiser. Connectivity to
another system on the same Guest LAN is fine.
I cannot ping VM TCPIP from Linux, or Linux from VM (VM TCPIP is my router).
Obviously there's no SSH or other traffic flow either.
I hit the archives because the problem sounded familiar to me, but I only
see problems with the dodgy SLES8 update from a couple of months back. I've
tried turning on fake_ll, which didn't change anything. I've tried applying
the most recent SLES9 kernel update (beyond what SP1 brought in), which also
didn't change anything. I don't want to have to go back to the pre-SP1
kernel, because the updated kernel was the reason I put on SP1 :-(
Other things I've checked include firewall rules (there are none), MTU size
(matches, and won't affect small pings anyway), routing in z/VM TCP/IP.
This z/VM system doesn't get much service attention (Q VMLAN says
VM63261) -- could it be some maintenance I need?
Any ideas? (Hopefully) Relevant displays below.
Cheers,
Vic -- 11:20pm here now so responses in the morning; hope you all have a
better today than I had! :)
