Advanced Disk Setup
Sophisticated system configurations require particular disk setups. To get persistent
device naming with SCSI devices, use a specific start-up script or udev. Logical Volume
Management (LVM) is a disk partitioning scheme that is designed to be much more
flexible than the physical partitioning used in standard setups. Its snapshot functionality
enables you to create data backups easily. Redundant Array of Independent Disks
(RAID) offers increased data integrity, performance, and fault tolerance. SUSE® Linux
Enterprise Server also supports multipath I/O. For details, see
IO
(page 251). Starting with SUSE Linux Enterprise Server 10, there is also the option
to use iSCSI as a networked disk. Read more about iSCSI in

6.1 LVM Configuration
This section briefly describes the principles behind LVM and its basic features that
make it useful under many circumstances. In

(page 126), learn how to set up LVM with YaST.
WARNING
Using LVM might be associated with increased risk, such as data loss. Risks also
include application crashes, power failures, and faulty commands. Save your
data before implementing LVM or reconfiguring volumes. Never work without
a backup.
