          see note:
          Huge number of alert log entries: 'WARNING: IO Failed...' 'WARNING: failed to read mirror side 1 of virtual extent ...' [ID 1274852.1]


          Contact your storage guys to see if theres an error, this is storage related.

            Hi , thanks i check the asm in both node
            [oracle@ccbs01 bin]$ ./srvctl status asm
            ASM is running on ccbs01,ccbs02
            [oracle@ccbs01 bin]$ ./srvctl status asm -a
            ASM is running on ccbs01,ccbs02
            ASM is enabled.
            [oracle@ccbs01 bin]$ ps -ef | grep smon

                  Had the same issue here.
                  It was storage-related.
