2 PowerVM Migration from Physical to Virtual Storage
1.1 Definitions
The following definitions will assist you in understanding the material located
within this publication:
Standalone servers Standalone servers are typically systems that do not
contain multiple logical partitions or any Virtual I/O
Servers.
Client or logical partition This is a partition on POWER®-based hardware that
has some level of virtualization. For example, CPU
and memory and may have some direct-attached I/O
hardware or I/O hardware virtualized by the Virtual
I/O Server, or both.
Local disks These are direct-attached SCSI or SAN disks.
Storage This is categorized as local or storage area network
(SAN) storage. The hardware disks comprising the
storage are descibed as either rootvg.
rootvg, data, and datavg rootvg is used to describe content that is used as the
base operating system necessary to boot the server.
All other disk contents will be given the generic label
of data disk and sometimes will also be referred to in
this publication as datavg.
1.2 Audience
This publication targets architects and solution designers who may be required to
design migration strategies that use physical-to-virtual migration techniques and
system administrators who may be required to perform such migrations.
Knowledge of the Virtual I/O Server and AIX is assumed, as well as intermediate
to advanced skills in storage systems.
