IPMP and 11gR2 Grid Infrastructure on Sun Solaris 10

11.2.0.1 clusterware fails to start or evict if IPMP is used for public or private network. This happened when I ran the root script. // <![CDATA[// Node eviction can also happen when IPMP fails over private IP from active NIC to other NIC in same group.

bug 9260196 is fixed in 11.2.0.2; for 11.2.0.1, fix is available in patch 9729439.  Applied this patch and re ran the root scripts.

Oracle Grid Infrastructure 11.2.0.1 does not support native multiple redundant network support. Therefore, an external redundancy mechanism must be used. Oracle Solaris provides two solutions: Trunking (Link Aggregation based) and IPMP (IP Multipathing).
