Deconfiguration is the act of disabling a component in the system. This happens when analysis

finds that a component has a serious fault. A components deconfiguration status is composed of

two parts:

• “requested state” – What the user or Analysis Engine would like to have the component set

to.

• “current state” – How the component is actually configured in the system.

IMPORTANT: Deconfiguration requests for components in active nPars can not be acted on until

the nPar experiences a power-off/power-on cycle.

Acquitting indictments

Acquitting refers to clearing the component indictment and deconfiguration statuses, and is done

when the part is serviced. Acquittals happen automatically in the following situations:

• Component insertion — HR will assume that a component inserted into the system has received

any required service. This applies to any components contained within the inserted unit as

well. For example, DIMMs and CPU sockets on an inserted blade will be acquitted. Any

deconfigurations will be reversed.

• AC power cycle or CLI poweron xfabric command — HR will assume that the required

service has been accomplished for the entire complex. All FRUs and sub-FRUs will be acquitted

and reconfigured.

• Cohort acquittal — When analysis of a single fault event results in indictment or suspicion

records against multiple components, the records are linked together. If one is acquitted, the

acquittal will be passed to the cohort FRUs as well.

For example, if a cabled fabric link between the XFM and IOX has failed, the analysis engine

will indict the cable connectors physical locations (representing the cable as the most likely

component failure). Acquittal of the fabric cable connectors after cable service will acquit all

for records.

• HR test commands — The test camnet and test clocks commands will acquit all

indictments specific to the test to be executed. Resources that fail the test will be re-indicted

as the test completes. The test fabric command acquits each type (fabric, CAMNet,

Global Clock) of indictment before initiating the test.

NOTE: Indictments indicating faults in subcomponents not targeted by the tests will not be

acquitted. For example, a blade indictment for CPU fault will not be acquitted by any of these

test commands.

• Start Link — Attempting to service a cabled link while in use will result in an indictment. The

stop link command prevents these indictments and alerts caused by service actions and

lights the appropriate LINK health LEDs to help identify the physical cable needing service.

The start link command clears the link health LEDs, acquits, and attempts link retraining.

• Manual Acquittal – The HR UI includes an acquit command that uses the component physical

location or resource path as a parameter. Like other acquittals, the acquittal will act on all

indictments for that component.

• Component resumes normal function.
