    i want to migrate data from a old storage to a new one.
    so i use LVM as migrate tools, first, i mirror all lv to new storage. then i unmirror and reduce all old disks.

    if the new storage is damaged, can i restore the vg using the disks split from the vg?

    hi, dont use cplv or chfs -a splitcopy.
    just use the old-style mirrorvg -s / syncvg / unmirrorvg.
    use rmlvcopy in case of lvm problems.
    but check at first if you can extendvg all new disks (problems with limits in classic vg)
