    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.

    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.
