**這個很大程度上是grid 11.2.0.1 的一個BUG，另外發現在CPU爲AMD時會觸發這個bug，而intel則不會。
執行root.sh腳本報錯

Adding daemon to inittab
Failed to start oracle-ohasd, error:
ohasd failed to start: Inappropriate ioctl for device at /u01/app/11.2.0/grid/crs/install/roothas.pl line 296.
或者可能如下錯誤：

解決方案
第一步：回退root.sh腳本操作

第二步：
方法1： 編輯$GRID_HOME/crs/install/s_crsconfig_lib.pm，查找if ($srv eq “ohasd”) { # Start OHASD
# Start OHASD後方插入下列代碼：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;
}
最後應該如下所示一樣：
# Check to see if the service is OHASD
if($srveq"ohasd"){
# Create the autorun file
my$AUTORUNFILE=catfile($SCRBASE,$HOST,$HAS_USER,"ohasdrun");
open(AUTORUN,">$AUTORUNFILE")
ordie"Can't
open $AUTORUNFILE for write: $!";
printAUTORUN"stopn";
close(AUTORUN);
s_set_ownergroup($HAS_USER,$HAS_GROUP,$AUTORUNFILE)
ordie"Can't
change ownership of $AUTORUNFILE: $!";
s_set_perms("0644",$AUTORUNFILE)
ordie"Can't
change permissions of $AUTORUNFILE: $!";
#
Add OHASD to inittab
print"Adding
daemon to inittabn";
s_remove_itab("cssd|evmd|crsd|ohasd")orreturn$FAILED;
system("$INIT
q");
sleep(5);
s_add_itab()orreturn$FAILED;
system("$INIT
q");
#

####################插在此處地方############################
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

return$FAILED;
}

$status=system("$CRSCTL

}elsif($srveq"crsexcl"){

#
Create the autorun file
（推薦）方法2：在執行root.sh腳本時出現Adding daemon to inittab的時候，在另一個窗口使用root立即執行以下命令：
#vi /etc/init/oracle-ohasd.conf
startonrunlevel[35]
stoponrunlevel[!35]
respawn
exec/etc/init.d/init.ohasdrun>/dev/null2>&1</dev/null
如果使用方法2：則在執行完畢root.sh腳本後也必須創建，否則重啓系統後無法自動啓動HAS

按照方法一的實施方法，會net配置錯誤，在安裝完成後還需要手動netca
所以比較推薦方法二
