Did you remove it from modprobe.conf (or whichever file suse uses) before the mkinitrd. if it's in there and run mkinitrd it will just add it back into the initrd and you'll have a dup Otherwise have them leave it offline in the gen would probably do it as well
Scotts method works, I have used it with RHEL myself William 'Doug' Carroll -----Original Message----- From: Linux on 390 Port [mailto:linux-...@vm.marist.edu] On Behalf Of Lester, Doug Sent: Monday, August 09, 2010 4:12 PM To: LINUX-390@VM.MARIST.EDU Subject: Re: Full volume restore of an LVM DASD I tried to test Scott's procedure and it appeared to work until I rebooted. Since the old DASD volume is not really out of commission, it is still available and is still used by LVM instead of the new volume. Please refer to the following display # pvscan Found duplicate PV 9yHc6x8geJQkTApxyf3c53CI0CTQpOOF: using /dev/dasdf1 not /dev/dasdc1 PV /dev/dasdf1 VG system-vg lvm2 [6.88 GB / 3.88 GB free] Before rebooting, I took the old volume offline as per Scott's instructions. I also ran "mkinitrd" and "zipl" hoping to prevent the old device from coming online during the IPL. Any suggestions on how to prevent the old DASD volume from coming online?

You just want to make sure those addresses are available and brought online by Linux when it comes up (and that you have no devices online that have duplicate uuid/lvm info on them!)
