I am using DBCA to setup ASM... when I get to the Create Disk Group screen it will not show me any candidate disks. I have changed the disk discovery path. This is what is currently showing in the  init.ora

init+ASM1.ora:background_dump_dest=/oracle/app/oracle/admin/+ASM/bdump
init+ASM1.ora:core_dump_dest=/oracle/app/oracle/admin/+ASM/cdump
init+ASM1.ora:user_dump_dest=/oracle/app/oracle/admin/+ASM/udump
init+ASM1.ora:instance_type=asm
init+ASM1.ora:asm_diskgroups=''
init+ASM1.ora:asm_diskstring='/dev/rdsk/c3t10d0*','/dev/rdsk/c3t19d0*','/dev/rdsk/c3t20d0*'
init+ASM1.ora:+ASM1.instance_number=1
init+ASM1.ora:+ASM2.instance_number=2

Why is DBCA not able to discover these disks?

Probably because of permissions.

Following the sym links to the /devices/ to the slice you want to use.

and chown oracle:dba  (depending on the user/group of your oracle install)

I usually have my slices setup using slice 3

Part      Tag       Flag      Cylinders    
  0 unassigned    wm       0 -     8
 3 unassigned    wm      10 - 14086    (which is the remainder of my disk)
