From d6b702d5791b47f735960ad1f6986e0a32768df6 Mon Sep 17 00:00:00 2001
From: Eduard Shishkin <edward6@linux.ibm.com>
Date: Thu, 11 Jul 2024 10:43:37 +0200
Subject: [PATCH] zipl/src: add basic support for multiple target base disks
. Modify disk_get_info() to process multiple sets of target parameters
provided by the helper script and store it in the array of "targets"
of the structure job_target_data;
. Besides the logical device, maintain an array of physical base disks
in the disk_info structure;
. Use the logical target device only to create bootmap (it is
automatically mirrored by the respective linux driver (dm, or md)
managing the mirrored target). In contrast, install bootstrap blocks
to each physical base disk individually, bypassing that driver;
. Report in verbose mode on which base disks the bootstrap
installation was performed;
. Use the following logic of setting @info->device (which is printed
as "Device...:" in verbose mode):
. source_auto - the target base disk is set;
. source_script - the target (logical) device is set;
. source_user - the device specified by user (via --targetbase
option), or config file is set.
