Roberto: There are two things you can try:
The right way is to boot the system off CD, mount all the devices, do a chroot to your disks, fix /etc/zipl.conf, do "mkinitrd ; zipl", and then shut everything down. Suse describes it in detail at https://www.suse.com/support/kb/doc/?id=7018376 The quick way assumes your boot partition isn't part of the LVM group and that you have a rescue system that's very similar to the one that's down. Mount the boot partition to a rescue system (say at /mnt). Then move some things around: # mv /boot /boot.orig # ln -s /mnt/boot /boot # cp -p /etc/zipl.conf /etc/zipl.conf.bak Edit /etc/zipl.conf as needed for the new disks. # mkinitrd ; zipl # rm /boot ; mv /boot.org /boot # mv /etc/zipl.conf /etc/zipl.conf.rescue ; mv /etc/zipl.conf.bak /etc/zipl.conf Then unmount and detach the disk from the rescue system. Make sure the rescue system is okay: # mkinitrd ; zipl The two systems have to be running the same kernel and this , but so far I've gotten away with it. PLEASE: read all the steps and think through them before you run. Much of this is pasted from my notes, but I haven't had to mess with zipl.conf when doing this.

Hello all, I defined 2 new z/VM 6.2.0 minidisks for a RHEL 6.0 VM to grow / FS, everything went right except I forgot to Persistently Setting DASDs Online with /etc/zipl.conf and zipl. Got "Refusing activation of partial LV lv_root. Use --partial to override." in next IPL.
