Good morning/afternoon/evening all A colleague is running into an issue installing GI 11.2.0.3 on a pair of RH 6.3 nodes. cluvfy passes on both nodes, but the installer itself fails with INFO: Validating for no private interface provided INFO: Flag oracle.install.crs.allowSingleNIC=false SEVERE: [FATAL] [INS-41112] Specified network interface doesnt maintain connectivity across cluster nodes. CAUSE: Installer has detected that network interface bond0 does not maintain connectivity on all cluster nodes. ACTION: Ensure that the chosen interface has been configured across all cluster nodes. This occurs for both public and private interfaces. Has anybody come across similar issues in their environment where node connectivity checks pass in the cluvfy tool, but fail at actual install? -- Niall Litchfield Oracle DBA http://www.orawin.info -- //www.freelists.org/webpage/oracle-l
