AutoYaST control file fails to detect Multipath devices

This document (7021221) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 12 Service Pack 2 (SLES 12 SP2)
AutoYaST
Device Mapper Multipath Path (DM-MPIO)

Situation

Using an AutoYaST file to install a server fails to detect the MPIO drive. The OS is intended to be installed with root on MPIO.

The autoyast file contained the following sections:
<general>
  <storage>
    <start_multipath config:type="boolean">true</start_multipath>
  </storage>
</general> 
<partitioning config:type="list">
<drive>
<!--
<device>/dev/mapper/3600507680190014da000000000000337</device>
-->
<type config:type="symbol">CT_DISK</type>
</drive>
</partitioning>

Likewise, LIBSTORAGE_MULTIPATH_AUTOSTART=ON was added to the kernel command line using uppercase letters, since the option is case sensitive.

If the <device><drive> is specified, the MPIO device is used for the installation, but fails if it's commented out. Since the customer wants to install many servers, they require the <drive> be commented out so autoyast will auto detect the MPIO drive.

Resolution

Change the device type from CT_DISK to CT_DMMULTIPATH.

Change from this:
<type config:type="symbol">CT_DISK</type>
To this:
<type config:type="symbol">CT_DMMULTIPATH</type>

Cause

The drive type designation "CT_DISK" limited auto detected drives to physical type hard disks.
