The RMAN database backup is failing with following errors:

MAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-03002: failure of backup plus archivelog command at 12/16/2014 04:32:04

ORA-19501: read error on file "/opt/oracle/base/oradata/ts_x1.dbf", block number 113536 (block size=8192)

ORA-27061: waiting for async I/Os failed

Linux-x86_64 Error: 5: Input/output error

Additional information: -1

Additional information: 1048576

Database is running in archivelog mode , Oracle version: 11.2.0.2.0. , OS :  Red Hat Linux

I do not want to set  " disk_asynch_io = false"   as this will bypass the asynchronous IO which is not appropriate.

How to fix these errors?

Please suggest

Regards,

MKS.
