On Windows Server 2008 R2, when I am trying to startup Oracle 11g database it shows an error:
SQL> startup ORACLE instance started. Total System Global Area 3206836224 bytes Fixed Size 2180024 bytes Variable Size 1996491848 bytes Database Buffers 1191182336 bytes Redo Buffers 16982016 bytes ORA-00204: error in reading (block 3, # blocks 8) of control file ORA-00202: control file: 'D:\APP\FROZEN\ORADATA\ORCL\CONTROL01.CTL' ORA-27070: async read/write failed OSD-04006: ReadFile() failure, unable to read from file O/S-Error: (OS 1117) The request could not be performed because of an I/O device error.
The disk is online.
Can any one help me how to resolve this issue?
