Folks Instance & CRS shutdown both seem to be Hanging for an internal Test 10gR2 RAC Setup. What approach / action should be considered? Will O.S. RE-BOOT of Both the Nodes in the Current State resolve the issues? P.S. Oracle version - 10.2.0.2 Solaris 10 On Node 1 Unable to shutdown the instance using srvctl & "shutdown immediate". Both Hanging.
