Graphical representation of OSI secondary states

Secondary states are almost always represented graphically by adding an icon to the top left corner of the object base element. The only exception is for the “Not Installed” Availability state, which is denoted by a change in the base element visual (as shown in table Other OSI secondary state representations).

How to read the When Applicable column

The meaningful representation of the OSI secondary states depends on the eight valid OSI primary states. These primary states are grouped in three categories: Out Of Service (OOS), In Service and Carrying Traffic (CT), and In Service and Carrying No Traffic (NT).

Out Of Service (OOS):
- Operational: Disabled, Usage: Idle, Administrative: Unlocked
- Operational: Disabled, Usage: Idle, Administrative: Locked
In Service, Carrying No Traffic (NT):
- Operational: Enabled, Usage: Idle, Administrative: Unlocked
- Operational: Enabled, Usage: Idle, Administrative: Locked
In Service, Carrying Traffic (CT):
- Operational: Enabled, Usage: Active, Administrative: Unlocked
- Operational: Enabled, Usage: Active, Administrative: Shutting down
- Operational: Enabled, Usage: Busy, Administrative: Unlocked
- Operational: Enabled, Usage: Busy, Administrative: Shutting down

Secondary state names

In Icon-based representations of OSI secondary states , the symbolic name Secondary State Definition that appears after each Secondary State Name corresponds to the static secondary state definition. For example, the In Test secondary state is defined by InTest , which corresponds to the static definition InTest.

Secondary state icons

It is possible to change the icon associated with a secondary state by using global settings, see Using global settings. The icon property name to be used with IltSettings.SetValue() must include the secondary state group, the secondary state definition, and the primary state. For example:

OSI.Repair.UnderRepair.OOS.Icon

where:
- Repair is one of the five OSI secondary state groups
- UnderRepair is the secondary state definition of the “Under Repair” secondary state (the only secondary state in the Repair group)
- OOS is the corresponding OSI primary state group (Out Of Service)

For more information on how to use global settings to modify the OSI secondary state icons, see Customizing the OSI state system.

Icon-based representations of OSI secondary states

Secondary State Name `Secondary State Definition`	When Applicable: OOS, NT, CT	Comment
Procedural Secondary State
Initialization Required `InitializationRequired`		Resource requires initialization before it can be made available.
Initializing `Initializing`		Resource is being initialized.
Reporting `Reporting`		Resource is initialized and test results are being returned.
Terminating `Terminating`		Resource is terminating.
Availability Secondary State
Degraded `Degraded`		Service is degraded. This could adversely affect the usage state.
Dependency `Dependency`		The resource cannot operate because some other resource of which it depends (i.e. a resource not represented by the same managed object) is unavailable. For example, a device is not accessible because its controller is powered off. The operational state is Disabled.
Failed `Failed`		Resource is subject to a fault that prevents it from being used. In most cases, this secondary state is coupled with an alarm, an outstanding alarm, or a loss of connectivity.
In Test `InTest`		Resource is undergoing test.
Log Full `LogFull`		Log is full. Log service has been made unavailable.
Not Installed `NotInstalled`	See Table A.3	Resource is not installed.
Off Duty `OffDuty`		Service has been made unavailable because of an ongoing time schedule.
Off Line `OffLine`		The resource requires a routine operation to be performed to place it online and make it available for use. The operation may be manual or automatic, or both. The operational state is Disabled.
Power Off `PowerOff`		Resource requires power, but is not powered. Most often, this resource is coupled with an alarm, an outstanding alarm, or a loss of connectivity.
Control Secondary State
Part of Services Locked `PartOfServicesLocked`		This value indicates whether a manager has administratively restricted a particular part of a service from the user(s) of a resource. The administrative state is Unlocked. Examples are: incoming service barred, outgoing service barred, write locked by media, read locked.
Reserved for Test `ReservedForTest`		Resource is reserved for test.
Subject to Test `SubjectToTest`		Resource is currently under test.
Suspended `Suspended`		The service has been administratively suspended to users of the resource. The resource may retain knowledge of the current users and/or request for usage, depending on the managed object class definition, but it does not resume performing services until the suspended condition is revoked. The administrative state is Unlocked.
Standby Secondary State
Cold Standby `ColdStandby`		The backup resource is not providing service and cannot immediately take over the role of the primary resource.
Hot Standby `HotStandby`		The backup resource is not providing service, but can immediately take over the role of the primary resource.
Providing Service `ProvidingService`		The backup resource has been put into service. (It currently takes over the role of a primary resource.)
Warm Standby `WarmStandby`		The backup resource is not providing service, but can immediately or within a short delay take over the role of the primary resource. (Data is mirrored to the backup resource at regular intervals.)
Repair Secondary State
Includes Under repair only. Outstanding alarm secondary states are considered as alarm representation cases and are represented as such.
Under Repair `UnderRepair`		Resource is currently under repair.

Other OSI secondary state representations

Secondary State Name `Secondary State Definition`	Visual (OOS only)	Comment
Availability Secondary State
Not Installed `NotInstalled`		Resource is not installed, is installed improperly, or is incompletely installed.

All other OSI primary state combinations indicate that the object is in an indeterminate state. In this case, the OSI secondary states are not applicable to the object.
