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

Figure 24 lists the different steps performed by the vmVirtProvider, LSM/VMM, and VCEM/VCM. The physical server

is powered-off and its associated Virtual Connect profile is unassigned. Meta-information (i.e., EFI boot entries) and the

logical server definition are sent to the vmVirtProvider of the target HP Integrity VM host. It adapts and translates

this information to a virtual environment (i.e., boot hardware path) and creates a virtual machine (or register if already

existing in NR mode). The last step is the power-on as requested in the target hosts’ screen.

Physical to physical (P2P’) offline moves

Physical to Physical (P2P) offline moves represent the migration of a logical server activated on a physical Integrity

blade to another physical Integrity blade. The target physical Integrity blade server may or may not have the same

hardware characteristics (CPU, mezzanines cards, and memory) as the source server. To reflect the fact that source

sand target have different hardware characteristics, we call this type of move: P2P’ (P to P-prime). In a Matrix OE 7.0

environment, supported P2P’ moves are BL8x0c to BL8x0c i2, BL8x0c i2 to BL8x0c, BL8x0c to BL8x0c, and BL8x0c i2

to BL8x0c i2.

When achieving such a cross-technology move using the HP Matrix OE visualization menus, the following

tasks are performed automatically by the different Matrix OE components:

1. Power down of the source system (if not already done by a system administrator)

2. Backup of the EFI configuration and meta-information

3. Un-assignment of the Virtual Connect profile of the source server

4. Assignment of the Virtual Profile on the target server

5. Restore of EFI configuration

6. Boot the server

Note: HP recommends to gently shutdown all applications, as well as the underlying server, before proceeding with a P2P’ offline move.

Achieving a P2P’ offline move

Assuming an existing physical logical server activated on an Integrity Blade BL860c, we propose to move it to an

Integrity blade BL860c i2, and discuss the different steps. The activation of a physical logical server is identical to

the activation of a virtual logical server and is explained in the HP Matrix Operating Environment 7.0 Logical Server

management user guide.
