SLES12 re-installation on LPAR with encrypted partitions

This document (7023724) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 12
SUSE Linux Enterprise Desktop 12
IBM Power 8


SUSE Linux Enterprise Server 12 is successfully installed on a IBM Power 8 LPAR with an encrypted SWAP partition.

Following a re-installation, the installation process asks for the previously swap encrypted password in order to use that partition.
After editing the proposal settings, selecting a LVM based installation and successfully finishing the installation, the server entered dracut following the reboot.


Work-around :
When redoing an installation, do NOT supply the LUKS password for /dev/vda2 (the formerly encrypted swap space);

-> Storage proposal:

  Set type of partition /dev/vda1 to Linux LVM (8E)
  Set up encrypted dm device on /dev/vda2
  Set type of partition /dev/vda3 to Linux LVM (8E)
  Create volume group system (39.98 GiB) from /dev/vda1 /dev/vda2 /dev/vda3
  Create root volume /dev/system/root (37.98 GiB) with btrfs
  Create swap logical volume /dev/system/swap (2.00 GiB)

  Create subvolume @/boot/grub2/i386-pc on device /dev/system/root
  Create subvolume @/boot/grub2/x86_64-efi on device /dev/system/root

Please observe that it now explicitly mentions "Set up encrypted dm device on /dev/vda2". 
During previous  re-installations this was not observed,  and the information that this was a LUKS device was lost.


YaST installation handling one or more partitions with a LUKS encryption layer directly on the partition and administrator changing the storage proposal during installation to "LVM based".
