AutoYaST control file fails to detect Multipath devices

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


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


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:
    <start_multipath config:type="boolean">true</start_multipath>
<partitioning config:type="list">
<type config:type="symbol">CT_DISK</type>

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.


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>


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