IT environments in organizations today face more challenges
than ever before. Server rooms are crowded, infrastructure
costs are climbing, and right-sizing systems is often
problematic. In order to contain costs there is a push to use
resources more wisely to minimize waste and maximize the
return on investment. Virtualization technology was
developed to answer these objectives.
More and more organizations will deploy (or are in the
process of deploying) some form of virtualization. However,
parts of an organization's systems may use legacy storage
equipment. In these contexts, knowing how to migrate from
physical, often direct-attached storage, to a virtual storage
environment becomes valuable.
This IBM Redbooks publication introduces techniques to use
for the migration of storage from physical to virtual
environments and introduces several new features in
POWER6 systems. These features include:
򐂰 The chkdev command, added in Virtual I/O Server 2.1.2
FP22 to assist in identifying p2v candidates and to
ensure that device identification is consistent
򐂰 Extensive use of NPIV technology for both disk and tape
򐂰 The use of file-backed optical technology to present
virtual CD media as a means of restoration
