My presentation :  Oracle ASM : Most asked 5 question
(in Azerbaijani  - Oracle ASM : Ən çox soruşulan 5 sual)

Oracleasm - Instantiating disk : failed

When I configure ASM disks with ASMLib on Oracle Linux 6.2
I got a error

This error is depend  with  SELinux. I  forget set disabled SELinux configuration.

You can disable SELinux on duration of installation Linux

or after installation with change /etc/selinux/config

It is very important for correct operations!

And following video demo showing solve problem when oracleasm createdisk fails.

You can found Oracle Support note : oracleasm createdisk fails with selinux enabled [ID 1430947.1]

Oracle recomended is disable SELinux before installation Oracle RAC!
