How to migrate HP-UX workloads between physical and virtual servers easily

Logical servers and portability groups
Logical servers and portability groups are key concepts in the Matrix OE and are heavily used for achieving
HP-UX OE migrations. A brief review is necessary to understand their role and how they are used in such operations.
Logical servers
A logical server is a set of configuration information that you create, activate (instantiate), and move across physical and
virtual machines. It contains the logical server definition and description including the server resources (number of CPU
cores, and amount of memory), and the server connections to storage fabrics and networks. A logical server does not
contain any boot image or data. Figure 1 shows the type of information stored in the logical servers.
Figure 1. Inactive logical servers
When activated (instantiated), a logical server is applied to the creation of a virtual machine using hypervisor-based
software or to a bare-metal server blade using HP Virtual Connect technology (profiles). Figure 2 shows the relationship
between the logical server manager, logical servers, and their activation.
