Permanent Oracle ASM raw access permissions to LVM volumes

Oracle ASM requires raw access to disk space, but I still want flexible LVM storage infrastructure. Therefore a lots of asmXX LVs was created in single "vg_data" VG. The VG was created as HOWTO LUNs on Linux using native tools recommends.

Because of raw access, these LVs have to have oracle:dba ownership. This can be done on-line, but let's fix it permanent using udev instruments.

# cat /etc/udev/rules.d/92-local-oracle-permissions.rules

Which attributes to choose is up to you. This command will help you to see them:

# udevadm info --attribute-walk --name=/dev/XXXX
  - OR -
# udevadm info --query=all --name=/dev/XXXX
