[linux-lvm] LVM - vgimport



Hi experts

I need some help about this problem. 
I need to backup my volume group oravg. So, I´m using shadow image (BCV) on my disks on same server, it´s same I make dd if=/dev/sdc1 of=/dev/sdd1 bs=1024k, but after it sync on disks, there are on pvscan /dev/sdc1 and /dev/sdd1 with same name. 
I can´t to import with "vgimport -f copy_oravg /dev/sdd1", because the disks is using same name allocate "oravg".
Can I change volume group in physical volumes inactive?
Can I change UUID on physical volumes inactive?
I see that HP-UX there are vgchgid command?

Best regards.

Renato.
