You can use 'chroot /mnt/local bash --login'
to change into the recovered system.
You should at least mount /proc in the recovered system
e.g. via 'mount -t proc none /mnt/local/proc'
before you change into the recovered system
and manually install a boot loader therein.

Finished recovering your system. You can explore it under '/mnt/local'.

  • Hello praditk,

    The SLE HA Extension includes the package rear23a which was added to restore SLES on ppc64le -https://scc.suse.com/packages?name=SUSE Linux Enterprise Server&version=12.3&arch=ppc64le&query=rear&module= . Have you tried this?

    Hello,

    we've the same problem using 2.3 as proposed by mfriesenegger.

    During recovery the last step :

    1) Confirm it is OK to recreate initrd and reinstall bootloader and continue 're ar recover'
    2) Edit restored etc/fstab (/mnt/local/etc/fstab)
    3) View restored etc/fstab (/mnt/local/etc/fstab)
    4) Use Relax-and-Recover shell and return back to here
    5) Abort 'rear recover'
    (default '1' timeout 300 seconds)
