Spec sections related to component restart admin operation:
1)3.2.2.1 Presence State:
A component is restarted by the Availability Management Framework in the
context of
error recovery and repair actions (for details, see Section 3.11) or in the
context of a
restart administrative operation (for details, see Section 9.4.7). Restarting a
component
means first terminating it and then instantiating it again (see Section
3.11.1.2).
Two different actions shall be undertaken by the Availability Management
Framework
regarding the component service instances assigned to a component when the
component
restart is needed:
• Keep the component service instances assigned to the component while the
component is restarted. This action is typically performed when it is faster to
restart the component than to reassign the component service instances to
another component. In this case, the presence state of the component is set to
restarting while the component is being terminated and until it is instantiated
again (or a failure occurs). Internally, in this particular scenario, the
Availability
Management Framework withdraws and reassigns exactly the same HA state on
behalf of all component service instances to the component as was assigned to
the component for various component service instances before the restart
procedure,
without evaluating the various criteria that the Availability Management
Framework would normally assess before making such an assignment.
• Reassign the component service instances currently assigned to the component
to another component before terminating/instantiating the component. In this
case, the presence state of the component is not set to restarting but
transitions
through the other presence state values (typically in the absence of failures:
terminating,
uninstantiated, instantiating, and then instantiated) as the component
is terminated and instantiated again.
The choice between these two policies is based on the
saAmfCompDisableRestart configuration attribute of each component (see the
SaAmfComp object class in Section 8.13.2).
2)9.4.7 SA_AMF_ADMIN_RESTART:
When this operation is invoked upon a particular instantiated component of a
service
unit, the other components of the service unit are not affected by this
operation, that
is, they are not restarted
So, if user invokes "restart" on a instantiated component then there are two
cases:
1)saAmfCompDisableRestart=false: In this case, restarting presence state for
the component will be observed. Also if the components has assignments, after
restart same assignments will be reassigned.
2)AmfCompDisableRestart=true: In this case, there will be reassignments of the
CSIs assigned to the component and component will transition through
terminating, uninstantiated, instantiating, and then instantiated.

** [tickets:#334] amf: admin restart of component is not fully implemented
w.r.t saAmfCompDisableRestart flag.**

when saAmfCompDisableRestart is set to SA_TRUE for the component, it is set
successfully but with error in syslog.

when restart is invoked on the component, operation returns ERR_NOT_SUPPORTED.
Sep 27 12:32:53 SLES11-SLOT-1 osafamfd[3263]: Component Restart disabled

when saAmfCompDisableRestart is set, component should go through all presence
states instead of restarting presence state ( sec 9.4.7 , page NO: 383 )
