Partition
Profiles
A partition does not actually own any resources until it is activated;
resource specifications are stored within partition profiles. The
same partition can operate using different resources at different
times, depending on the profile you activate.
Each logical partition
has at least one partition profile. You can have more than one profile
for a partition. However, you can only activate a partition with
one of its' profiles at a time. One profile is designated as the
default profile. It is this profile that is activated if another
is not specified.
When you
activate a partition, you enable the system to create a partition
using the set of resources in a profile created for that partition.
The system will attempt to allocate the resources you assigned to
the profile. If you have over-committed resources, the partition profile
will not be activated.
Partition profiles are
not affected by changes you make using the DLPAR feature. If you
want permanent changes, you must then reconfigure partition profiles
manually. For example, if your partition profile specifies that
you require two processors and you use DLPAR to add a processor
to that partition, you must change the partition profile if you
want the additional processor to be added to the partition the next
time you use the profile.
Manufacturing Default Configuration
The initial
partition setup of your managed system as received from your service
provider displays one logical partition with one partition profile.
The name of this partition is the serial number of the system. The
name of the profile is Default.
A partition
profile in the manufacturing default configuration has all of your
managed system’s resources. If you desire, you can install
an operating system on this partition and use this partition as
the only partition on the managed system. Because all of the hardware
(both required and desired) are assigned to this partition, no other
partitions can be started when this partition profile is running.
Likewise, a partition profile in the manufacturing default configuration
cannot be started while other partitions are running.
