During the partition validation process, the HMC compares the logical
partition information in the system plan with any existing logical
partitions on the managed system to ensure that the system plan can
deploy successfully to the target managed system.
Any existing logical partition found on the managed system must
appear in the system plan and must match the system plan as it appears
on the managed system. For example, hardware on the managed system
that is referenced by the actual partition must at least match the
hardware referenced by that same partition in the system plan. When
validating an existing logical partition, the
HMC validates the following
items for that logical partition:
- Whether a logical partition in the system plan has the same partition
ID and name as the existing logical partition specified in the machine
default configuration.
- Whether an existing logical partition has partition profiles that
match each partition profile specified for the logical partition in
the system plan.
- Whether the partition profiles for any existing logical partitions
contain the resources specified in the corresponding partition profiles
in the system plan.
- Whether the partition on the managed system has only those same
virtual adapters and adapter types (and that they use the same adapter
ports) as those specified for the partition in the system plan.
For example, if the server has an existing logical partition with
a partition ID 1, the HMC examines
the logical partition in the system plan that has a partition ID of
1. If this logical partition exists and has a partition profile that
is named SUPPORT, the HMC looks
at the existing logical partition to see if it also has a partition
profile that is named SUPPORT. If so, the HMC verifies that the resources
specified in the SUPPORT partition profile in the system plan are
contained in the SUPPORT partition profile in the existing logical
partition.
When the
HMC validates
partition profiles, it compares the following resources in the partition
profiles:
- Processor and memory amounts,
including 5250 commercial processing workload (5250 CPW) where applicable
- Physical I/O slot assignments
The following examples illustrate how the
HMC compares resources
in the partition profiles during the validation process to determine
whether the system plan is valid for a managed system:
- If the SUPPORT partition profile in the system plan specifies
2 GB of memory and the SUPPORT partition profile for the existing
logical partition specifies 3 GB of memory, the amount of memory is
valid.
- If the SUPPORT partition profile in the system plan specifies
4 GB of memory and the SUPPORT partition profile for the existing
logical partition specifies 3 GB of memory, the amount of memory is
not valid.
- If physical I/O slot P1 is assigned to the SUPPORT partition profile
in the system plan but not to the SUPPORT partition profile for the
existing logical partition, the physical slot assignment is not valid.
- If physical I/O slot P2 is not assigned to the SUPPORT partition
profile in the system plan, it does not matter whether slot P2 is
assigned to the SUPPORT partition profile for the existing logical
partition.
