526 CRS-4124: Oracle High Availability Services startup failed

While Install the Oracle Grid infrastructure, I got CRS 4124 error as below:

 

CRS-4124: Oracle High Availability Services startup failed.
CRS-4000: Command Start failed, or completed with errors.
ohasd failed to start: Inappropriate ioctl for device

ohasd failed to start: Inappropriate ioctl for device at /u01/app/oracle/product/11.2.0/grid/crs/install/roothas.pl line 296.

After some goggling, I found the post here had the same issue. The root cause is because the Oracle Grid infrastructure 11.2.0.1 does not support REL 6 and its compatible distribution like OEL 6.3.

 

The web page also provide the work around and alternately , we can use the REL 6 compatible version 11.2.0.3.  Note: 11.2.0.3 is only available from Oracle Support ( http://support.oracle.com/)

 

I have tried the work around and it looks ok. The only thing different then the post is the line should be 992.

 

my $UPSTART_OHASD_SERVICE = "oracle-ohasd";

my $INITCTL = "/sbin/initctl";

($status, @output) = system_cmd_capture ("$INITCTL start $UPSTART_OHASD_SERVICE");

if (0 != $status)

{

error ("Failed to start $UPSTART_OHASD_SERVICE, error: $!");

return $FAILED;

}

/etc/init/oracle-ohasd.conf

# Oracle OHASD startup

start on runlevel [35]

stop on runlevel [!35]

respawn

exec /etc/init.d/init.ohasd run >/dev/null 2>&1 </dev/null

 

 

To roll back the root.sh

$GRID_HOME/crs/install/roothas.pl -deconfig -force -verbose
