Deploy Oracle11. 2-Node RAC with ASM on RHEL 6.4 64bit Platform


We had installed OS of RHEL 6.2 and we are struggling to get ASMLib for same version

We did googling  and R&D on OTN Forum OCFS2 vs ASM for RHEL-6.0 onwards

we decided to go with ASM so we have only choice to format existing RHEL 6.2 and reinstall RHEL 6.4 Operating System

OCFS2 RPM not available from RHEL-6.0 onwards. Below is the work-around.

• Install RHEL-5.x. OCFS2 RPM available for suitable kernel version.
• Install RHEL-6.4 or above (In this we have kmod-oracleasm) RPM available from RHN (RedHat Network)
• Install Oracle Unbreakable Linux-6.0 (We need to check Licensing part for production setup). Both OCFS2 and ASM Library RPM available with this release.
• Anyone can create UDEV rules is also for disk management. (So far we have not used this option)


we have Storage of Dell PowerVault MD Series

we are facing issues with Device mapper multipathing

we fixed the multipathing issue and you can refer final configuration as reference
multipath.conf for Dell Server with RHEL 6.4

We started to install GI

but during execution of on node-1 we got below error

: Inappropriate ioctl for device (Doc ID 1557677.1)

We had refer below metalink note and decided to go with

Oracle Metalink-RHEL6 with ohasd failed to start Inappropriate ioctl for device

We don’t have setup of so we were download the same


We had tried installation of GI failed on node-1

Did not succssfully configure and start ASM at /u01/app/11.2.0/grid/crs/install/ line 6763.

Refer OTN

apparently using the name CLUSTER as your Disk Group Name isn’t allowed.

Once I changed that value it installed successfully

again we had manually remove GI installation using below commands from both the nodes


Deconfigure Oracle Clusterware without removing the binaries:

Log in as the root user on a node where you encountered an error.

Change directory to $GRID_HOME/crs/install. For example:
# cd $GRID_HOME/crs/install

Run with the -deconfig -force flags on all but the last node.
# perl -deconfig -force

Deinstall Command for Oracle Clusterware and ASM

$ cd /u01/app/11.2.0/grid/deinstall/ 
$ ./deinstall 


Start the GI and Installation and this time we have given ASM Disk name as ‘CLSTR’

finally I had successfully installed GI 🙂

then we were go ahead for below steps

Oracle SWONLY Installation

Create ASM Disk Group

Create RAC Database with below standard practices

#Please note down below parameter for configure the multiplexing controlfile and redolog file


We had create +ORADATA1 for applications purpose

You can check control file Location

show parameter control_files

You can check REDOLOG Location



Let me know if any questions
