Introduction
This document describe steps to configure ASMLIB on Oracle Linux 6.6.
Environment:-
Operating System: Oracle Linux 6.6
Database: - 11.2.0.4
In my case Grid Infrastructure installed on both node, so I choose one node to configure database link.
Software Needed:-
1- Oracle ASMLIB Download from Here.
2- Oracle Linux 6.6

First of all Download the ASMLIB package and Upload them to the server you have two option download
them automatically using yum command or manually if you don’t have internet access.
Too see the kernel version:-
[root@test01 ~]# uname -a
[root@test01 ~]# cat /etc/oracle-release
Using Yum run the following command:-
yum install kmod-oracleasm
yum install oracleasm-support
yum install oracleasmlib
Or after download the package and upload them to the server use the rpm command:-
rpm –ivh kmod-oracleasm-2.0.8-4.el6_6.x86_64.rpm
rpm –ivh oracleasmlib-2.0.4-1.el6.x86_64.rpm
rpm –ivh oracleasm-support-2.1.8-1.el6.x86_64.rpm
It’s mandatory to install 3 packages don’t ignore any.
Now the installation for ASMLIB is done, we need to partition the new disk using fdisk command.
[root@moirac01 ASM]# fdisk -l
Disk /dev/sda: 268.4 GB, 268435456000 bytes
255 heads, 63 sectors/track, 32635 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00031164
Disk /dev/sde: 549.8 GB, 549763153920 bytes
255 heads, 63 sectors/track, 66838 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000d23a3

# fdisk /dev/sdc
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0xc8322e8f.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-1305, default 1):
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-1305, default 1305):
Using default value 1305
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
Now we can configure ASMLIB using the below command:-
#/usr/sbin/oracleasm configure -i
Configuring the Oracle ASM library driver.
This will configure the on?boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets ('[]'). Hitting without typing an
answer will keep that current value. Ctrl?C will abort.
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
