DESCRIPTION
"This MIB defines the administrative commands and status related to a
managed object. These objects are managed by the combination of three
attributes that are termed OSI States attributes.
This MIB follows ISO/IEC 10164-2 CCITT Recommendation X.731 with
the following interpretations and extensions.
This MIB contains managable objects containers. The table
groupAdminTable contains group of entities that are manageable
uniquely (in another admin table) or in group( groupAdminTable).
The management state of a managed object represents the
instantaneous condition of availability and operability of the
associated resource from the management point of view.
Managed objects have a variety of state attributes that express
and control aspects of the operation of their associated
resource that are peculiar to each. However, the management
state is expected to be common to a large number of resources
and, for this reason, is standardized; it expresses key aspects
of their usability at any given time. We used three primary
factors to allocate the management state of a managed object.
These are:
operability : indicates whether or not the resource is
operational.
usage : indicates whether or not the resource is
actively in use at a specific instant and, if
so, whether or not it has spare capacity for
additional requests at that instant.
administration : indicates the current maintenance state of a
group. This attribute reflects the result
of an operator-initiated maintenance request.
The status of the managed object is closely related to the status of
its children. These status are affected by external events such
as administrative commands. The behavior of the managed object
to these events is explained below.
event : receive an administrative lock (graceful) command
for a group:
1) The administrative state of the group (groupAdminState) is
changed to SHUTTING DOWN.
2) All children are notified to set their usage state to
IDLE UNUSABLE gracefully.
3) The children change their usage state to IDLE UNUSABLE
as soon as their activities end.
4) When the usage state of all children have been set to
IDLE UNUSABLE, the usage state of the group (groupUsageState)
is changed to IDLE UNUSABLE.
5) The administrative state of the group (groupAdminState)is
changed to LOCKED.
event : receive an administrative lock command (non graceful)
for a group:
1) All children are notified to set their usage state
to IDLE UNUSABLE immediately.
2) The children change their usage state to IDLE UNUSABLE
abruptly.
3) When the usage state of all children have been change to
IDLE UNUSABLE, the usage state of the group (groupUsageState)
is changed to IDLE UNUSABLE.
4) The administrative state of the group (groupAdminState) is
changed to LOCKED.
event : receive an administrative unlock command for a group
1) All children are notified to set their usage state to
IDLE if:
* the administrative state of the child is
UNLOCKED AND
* the administrative states of all its parents are
also UNLOCKED AND
* the operational state of the child is ENABLED AND
* the operational state of all its parents are
also ENABLED.
2) The usage state of the group (groupUsageState) is changed
to IDLE if:
* the administrative state of all its parents are
also UNLOCKED AND
* the operational state of the group is ENABLED AND
* the operational state of all its parents are
also ENABLED.
3) The administrative state of the group (groupAdminState)
is changed to UNLOCKED.
event : An operational problem is discovered with a group
1) All children are notified to set their usage state to
IDLE UNUSABLE abruptly.
2) All children change their usage state to IDLE UNUSABLE
abruptly.
3) When the usage state of all children have been set to
IDLE UNUSABLE, the usage state of the group (groupUsageState)
is changed to IDLE UNUSABLE.
4) The operational state of the group (groupOpState) is changed
to DISABLED.
event : An operational problem is resolved in a group
1) All children are notified to set their usage state
to IDLE if:
* the administrative state of the child is
UNLOCKED AND
* the administrative state of all its parents are
also UNLOCKED AND
* the operational state of the child is ENABLED AND
* the operational state of all its parents are
also ENABLED
2) The usage state of the group (groupUsageState) is changed
to IDLE if:
* the administrative state of the group is UNLOCKED AND
* the administrative state of all its parents are
also UNLOCKED AND
* the operational state of all its parents are
also ENABLED
3) The operational state of the group (groupOpState) is changed
to ENABLED"
