T2000 architecture reset on moderate-to-intense disk IO? 2006-06-30 - By Kevin Closson
Back
A new customer has an issue where their new T2000-based RAC
cluster running Oracle clusterware (CRS) has a node go to reset under
moderate to intense disk IO workload (10GR2, Solaris 10). The node that
is being connected to drops to the OK prompt and that's it. There are no
logs or messages in any logfile, CRS or otherwise.
Does anyone have any similar experiences?
...CRS reboots? Of course! Questions first. Is the customer using
straight CRS or is it
integrated with Sun Clusters or Veritas (yes 10gR2 will do that
regardless
of the "Marketing Machine" literature). To verify, do this:
$ ls -l /opt/ORCLcluster $CLUSTERDIR/lib/libskgxn2.so
With the answers to these questions, I can probably help you make some
sense of it all.
