90 PowerVM Migration from Physical to Virtual Storage
5.1 Direct-attached SCSI partition to virtual SCSI
This migration method describes a scenario where a logical partition with local
direct-attached disk is migrated to a Virtual I/O Server in the same systems
enclosure or CEC, as shown in Figure 5-1.

On the client partition: part 1
The client tasks to be performed involve the identification of the resources to be
migrated. While not mentioned as a step in this example, your local procedures
may also require that a valid backup is taken before performing the migration.
1. The first step is to perform identification tasks to ensure that the correct disks
are migrated. In this example a single disk root volume group is migrated.
These same procedures apply regardless of how many disks and volume
groups one is required to migrate:
a. List the physical disks using the lspv command:
# lspv
hdisk0 002631cd31ad04f5 rootvg
active
#
b. Identify the disks that will be migrated using the lsdev command:
# lsdev -Cc disk
