Using LDL DASD devices in SLES12 FCS and SLES12 SP1.

This document (7017519) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 12
SUSE Linux Enterprise Server 12 Service Pack 1 (SLES 12 SP1)
IBM DASD - Direct-Access Storage Devices

Situation

When a DASD system is being LDL formatted using SLES 12, the disk is activated on the 'DASD Disk Management' panel, but does not provide a warning about it's LDL formatting.

When trying to create or change the partitioning scheme using YaST, this will than error out with the following message : 'DISK_CREATE_PARTITION_PARTED_FAILED' along with system error code : -1007

Resolution

The LDL DASD devices, unlike other types of disks, cannot be partitioned - even the partition table cannot be created on such disks and they must be used as whole.

In order to avoid those errors and aborting the installation process, do not attempt to partition the LDL DASD devices and always use them as whole.
This has been corrected for SLES 12 SP2 onward, which will correctly detect DASD devices.

Cause

YaST does not detect the LDL DASD type of the devices, and does not prevent any partitioning events on such disks, which will lead to errors at later stages of the installation.
