Baseline usage for the PPU program is included in the minimum monthly
payment. Your baseline usage is defined in your Master Lease Agreement
with HP. Inactive partitions in PPU systems are covered under baseline
usage.

| |
|
 | NOTE: An inactive partition is reported as “IDLE” in
the measurement “Method” column, on the PPU web portal
report. |
|
| |
|
An inactive partition has all of the cells in the partition
inactive. An inactive cell is either powered off, or in a state
prior to boot-level control (prior to BCH/EFI), defined as “waiting
on SINC_BIB”.
|
| |
|
 | IMPORTANT: If you shut down a partition for 24 hours or more,
you should also power it off to avoid additional charges. To power
off the partition, execute the PE command from the system MP. |
|

|
For HP-UX systems, to configure a partition to “waiting
on SINC_BIB”, execute the following command:
If you have already shut down your partition without these
options, you can still place it into an inactive state by doing
one of the following through the GSP interface:
Enter the RR command
to put the partition in a “waiting on SINC_BIB” state.
Enter the PE command
to power down all the cells in the partition.
For Windows systems, use a menu path of Start > Shutdown to shut down the Windows partition. Once the partition
is shut down you can put it into an inactive state also by using
one of the GSP interface commands:
Enter the RR command
to put the partition in a “waiting on SINC_BIB” state.
Enter the PE command
to power down all the cells in the partition.
HP receives usage reports from active partitions in your PPU
system. Any inactive partitions are identified in the PPU usage
reports.

|
| NOTE: At least one partition in the complex must always be
active so that usage and inactive partition information can be reported
to HP. |

Active cell boards, which are assigned to active partitions,
must have at least one active core. If your partition does not have
any near-term need to have at least one core active per active cell
board, then you can do one of the following:
Deactivate
the partition.
Unassign cell boards from
partitions. When you unassign a cell board from a partition, all
cores on that cell board are inactive. Unassigned cell boards are
covered under the baseline usage.
Failed Partitions
When a partition fails, and you no longer want to report any
usage for that partition, you can do one of the following through
the GSP interface:
Reset the failed
partition, by entering the RS command.
Power down all of the cells
in the failed partition by using the PE command.
The other partitions in the complex report the failed partition
as inactive.
Dual-core and Inactive Cells
When a partition contains dual-core processors, then if PPU
is running on another partition in the complex, PPU may need to
make an assumption about the number of cores per processor and report
the number of cores for the inactive partition as if it contained
single-core processors. (This only affects the value TotalCPUs in
the usage report.) For systems running PPU V8, the assumption is
made only if all cells in the partition are inactive; if any cell
in the partition is active, PPU can determine the correct number
of cores per processor for the cells in the partition. For systems
running PPU V7, PPU assumes single-core processors for any cell
that is inactive in a partition.
