Grid infrastrcture multicast issue - Oracle Bug 9974223

When installing 11.2.0.2 grid infrastructure at the part of root.sh command, it runs successfully on the first node, but the subsequent nodes are failed on private NIC “Multicast Failed for eth2 using address 230.0.1.0:42000”.  This is Oracle Bug 9974223

Failed to start Oracle Clusterware stack

Failed to start Cluster Synchronization Service in clustered mode at /apps/grid/11.2.0/grid/crs/install/crsconfig_lib.pm line 1016.

Before kicking off the runInstaller  RAC grid infrastructure software, you should run mcasttest utility to test the availability of muticast addresses.  It can be downloaded from Oracle metalink Note:  1212703.1

You should apply patch Oracle Bug 9974223 to grid home before running root.sh (opatch napply -local -oh /apps/grid/11.2.0/grid -id 9974223)

If you already ran root.sh on the first node and it was successful but failed on the second node, then do the following steps:

crsctl stop cluster all

crsctl stop crs

 Prior to applying this part of the fix, you must invoke this script as root to unlock protected files.

 As root:               <CRS_HOME>/crs/install/rootcrs.pl –unlock

As oracle:            opatch napply -local -oh <CRS_HOME> -id 9974223

As root:                <CRS_HOME>/crs/install/rootcrs.pl –patch

Then continue on the subsequent nodes, as root run ./root.sh
