Hi,
was the entire system hanging or only the network connections?
I have seen an errror like this where network connections were hanging
for about 30 minutes and then all of a sudden everything was working
again. It turned out to be an OSA firmware bug, but was fixed 2-3 years
ago. If your OSA levels are more current, then better investigate in the
direction that Mark suggested ;-)
Regards,
Sven

Hi listers,
Does anybody have an idea/suggestion/solution to what I describe below?
IBM Z10 LPAR running SUSE SLES 10 SP4
Other day some external applications couldn´t connect to the data base,
neither to the SMB, neither do SSH (console) running on it.
All appls stayed hanging for about 20 minutes.
All processing was resumed without further notice AND WITHOUT ANY CORRECTIVE
ACTION.
No hardware errors were logged at machine HMC.
NO OS (Linux) error logged.
The switch just behind the OSA was responding normally.
We suspect of the OSA card because the ping had no answer DURING THIS
PERIOD.
More: we have an extra OSA card available for contingence.
Is there a way to configure "a kind of multipath" to automatically start up
in case of such faults?
