We do this and do not have an issue. When we restore an lvm DASD it drops right back into place. I thought it went by the formatted volume name, not the real dev name.

In the case of a DASD hardware failure, I would like to be able to restore to a new volume and make the necessary changes for Linux to recognize the new volume. This does not appear to be a problem unless the new DASD is part of LVM. Perhaps someone can give me some guidance using the following scenario. Please keep in mind; this is a SLES10 SP3 s390x LPAR installation. Unfortunately, we do not run Linux under z/VM. Example: If device 2912 has a hardware failure, I can restore to another volume (say, 372f). I would also restore the other 2 volumes to the original devices to remain in sync, unless someone can offer a better suggestion. How do I get Linux/LVM to recognize 372f instead of 2912?
