There is an issue on both AIX
6.1 TL08 SP01 and AIX 7.1 TL02 SP01 (ONLY) This issue affects ALL Oracle
Database RAC customers running on these 2 SP levels. The issue occurs
during the installation of the Grid/Clusterware software.
The symptoms that installation may observer are:
1) root.sh works fine on first node
2) root.sh works fine on 2nd node up until the final restart of the cluster.
3) WARNING - all the network verification steps in the OUI/cluvfy will PASS but the issue will still occur.
Looking at the CRS logs will show that the disk heartbeat is working fine but NO network heartbeat could be established.
The APAR efix (see numbers below) is marked HIPER by AIX support for anyone doing anything with UDP (not just Oracle).
This basically means "This fix is required" for both AIX 6.1 TL08 SP01 and AIX 7.1 TL02 SP01.
Since this is a HIPER bug, the ifix has been built and is available immediately for download.
The download information is included in the APAR - follow these links.
