How restore from ASM to a new server? We have a machine that crashed completely. 
The ASM disks are fine. Is it possible to mount the old ASM disks to a new machine and then restore the datafiles/redo files/ control files/everything to the new database?

Please note I don't want to restore from backup. I need to restore everything on ASM disks to new hardware with fresh OS and fresh database installation. 
Is that possible? if yes, how?

We are running Oracle 11gR1 database on Redhat Linux.
You can use RMAN for this.
There is some documentation I suggest you read in order to accomplish this easy way:
