There are several ways to get ASMLIB, we can download it from the OTN here, or we can download it from from ULN (Unbreakable Linux Network).
Also it comes in the the Unbreakable Linux media, but if you are not subscribed to ULN and you are not using Unbreakable Linux then most people go to the OTN, where you have to select your Linux flavor and then navigate to the correct file according to the linux kernel and then download the 3 files one by one.
Once you have the public YUM enabled do as root:
|
1
|
yum install oracleasm-support oracleasmlib oracleasm-`uname -r` |
ET VOILA!!! it will take just one minute to complete!.
Here is an example on a CentOS 5.4

Then we need to create all disks, change ASMLIBDISK1 according to your naming conventions:

/usr/sbin/oracleasm createdisk ASMLIBDISK1 /dev/sdb1Writing disk header: doneInstantiating disk: done |
and finally scan and list the disks

Find more of ASM here.
Good luck!
