Make sure that you can get from haoscar to oscarnode1 - quite often
cluster setup would only allow head-compute node communication but not
compute-compute node. Try ping or telnet to confirm that you can talk
between the two. If this works, check /var/pcp/config/pmcd/pmcd.conf
for any [access] configuration. Check which port pmcd is using. If
nothing helps, then come back.
