Replace linux native multipath with PP

Hi all

I've to replace native multipath on a Oracle linux with oracle RAC and ASM with Powerpath 6.

I can't find a document that explain steps to do this.

I'm planning these steps.

1.  Mask emcpower device in lvm.conf

     vi /etc/lvm/lvm.conf

          filter = [ "a/emcpower.*/", "r/sd.*/", "r/disk.*/" ]

2. Install powerpath

     rpm -ivh EMCpower.LINUX-*.rpm

3. Configurare PP license

     emcpreg -install

4. Disable native multipath

Edit /etc/multipath.conf so that it contains only the following lines:

          blacklist {

               devnode "*"

          }

     chkconfig multipathd off

     dracut /boot/initramfs-wo-DM-$(uname -r).img $(uname -r)

Add a new boot entry with the initramfs file created in previous step in the

/boot/grub/menu.lst

5. start PP

/etc/init.d/PowerPath start

6. check all device

Are these steps correct?

thanks
