Chapter 9. Migration of existing LPAR profiles to HMC 257
9.4.1 Information gathering and pre-sales planning
In the first scenario, the current system has two OS400 LPARs (P0 and P1) and consists of
the 810 system unit and one 5094 tower. All of the P0 Primary partition resources are located
in the 810 system unit. All of the resources for the P1 Secondary Partition are in the 5094
tower. A Primary partition no longer exist in the System i5 systems. However, in this case
there is production work done in the Primary partition of the 810 which requires this partition
to be migrated to the 520.
As the information gathered is reviewed, you should consider ways to migrate to the new
System i5 system with the least amount of disruption or changes. Particularly consider ways
to move over intact the essential resources of the Primary partition at migration time (Console
and Disk IOA and all Disks including the load source). This will greatly simplify the migration
process by avoiding the reload of the partitions. Figure 9-1 is a general illustration of the
Current and Proposed Systems for both scenarios.
