Disks
This is the lowest level of device. All devices that may be accessed as a physical
disk are treated as disks.
Segments
Segments consist of partitions and other memory regions on a disk, such as the
master boot record (MBR).
Containers
These are the counterparts of volume groups in LVM.
Regions
The available devices are grouped into LVM2 and RAID here.
Volumes
All devices, regardless of whether they are represented by a real partition, a logical
volume, or a RAID device are available with their respective mount points.
If you choose to use EVMS, you must replace your device names with the EVMS device
names. Simple partitions are found in /dev/evms/, logical volumes in /dev/evms/
lvm/, and RAID devices in /dev/evms/md. To activate EVMS at boot time, add
boot.evms to the boot scripts in the YaST runlevel editor. See also
"Configuring System Services (Runlevel) with YaST"
For More Information
For information about using EVMS to manage storage resources, see the Storage Ad-
ministration Guide that is available in /usr/share/doc/manual/sles-stor
_evms_en after installing the package sles-stor_evms_en. More common in-
formation about EVMS is also available in EVMS User Guide
.sourceforge.net/users_guide/] at the EVMS project
.sourceforge.net/], hosted on SourceForge*.
7.2 Soft RAID Configuration
The purpose of RAID (redundant array of independent disks) is to combine several
hard disk partitions into one large virtual hard disk to optimize performance, data secu-
rity, or both. Most RAID controllers use the SCSI protocol because it can address a
