After creating VG and recheck, I can see that everything is fine for now.

And the path is also ok now.

HDISK1 and HDISK8 are empty disks. Create a volume group on it and check it out. :-)
How can you know they are empty disks?As we can think the system is using it as non-LVM disks? And second question is, the multipath should also work for them right? Why after adding to LVM, the multipath starts working? Smilie
