Figure 37 nPartition Health Status
Resource health policy
The following are the resource health policies:
1. Partitionable resources
a. Blades and Iobays are the nPar assignable resources. At the time of nPar activation only
the health of the blades and iobays are considered. (Exception failure_usage policy).
b. CPU cores, memory and Root Ports (RPs) are the vPar assignable resources. At the time
of vPar activation, the health of CPU cores and RPs are considered.
2. Non-partitionable resources
a. Partitioning subsystem does not keep track of the health of the non-partitionable resources
like xfm (cross-bar), GPSM, fans and so on.
b. If a cross-bar is deconfigured, then partitions may not be activated. However, the
partitioning subsystem will not be able to give any additional information for this case.
3. Health is hierarchical
a. The health of the resources is hierarchical. And the hierarchy is as seen in the resource
path. If a blade is deconfigured, then all the resources under the blade are considered
as deconfigured for activation.
b. There is one exception. Enclosure health is not taken into consideration in the hierarchical
health.
4. Deconfigured resources are excluded
a. If a resource is deconfigured (including parent deconfigured), then the resource will not
be activated. It will be excluded from the list of resources that are passed to the
downstream firmware components by the Partitioning subsystem while requesting
activation.
b. If a resource is currently deconfigured, but it got acquitted back in HR, then that is a
healthy resource. Partitioning subsystem will mark the resource as healthy and will proceed
with activating it.
5. Indicted resources are included
a. Indicted resources are considered as healthy resources for activation.
b. However, an nPar can be marked “degraded” if it owns any indicted resources apart
from the deconfigured resources.
6. Deconfig failure usage policy
