ASMLib is best practice for managing ASM on Linux, it may happen that a database server that was configured a couple of years ago with ASM 10g R1 is still using raw devices, or that a new ASM 10g R2 or even 11g was configured using block devices instead of ASMLib.

This lab explain the procedure to migrate these devices to ASMLib.
