Oracle introduced the asmcd utility already in 10g database, but with limited shell commands. Although we expected oracle to come up with advanced shell capabilities in 11g , a little has been done, but still very helpful.
A very nice feature allows us to migrate (export) asm files out to an external file system. The big plus here is that no database needs to be mounted on the machine where we would like to mount the asm disk groups on. For instance, you can use a storage utility to create a snapshot of your ASM disks and present them on a different machine where you want to them to be backed up. This is nice especially where you have a backup tool (evault , for example) that does not support ASM.
In the attached pdf, you will find all the steps and scripts to design such a configuration.
To make it easier on everyone, I put everything down in the following pdf:
