Special Considerations
Inactive Partitions in PPU Systems
Appendix B62
Cell boards assigned to active partitions must have at least one active
processor. If your system/partition does not have any near term need to
have at least one processors active on the system, then you can either:
1. Inactivate partitions (or)
2. Un-assign cell boards from partitions. When you un-assign cell
boards from partitions there are zero active processors on that cell
board. Un-assigned 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:
• Reset the failed partition, by entering the RS command via the GSP
interface (or)
• Power down all of the cells in the failed partition, by using the PE
command via the GSP interface
If one of the above is done, the other partitions in the complex report the
failed partition as inactive.
