This class represents a zSeries® Coupling Facility, which is the system that manages a Sysplex (System Complex).

The module name of the CMPI provider that is registered for a CIM class which is used by the cimprovider command line tool for the administration of CMPI providers is

• IBMzOS_CouplingFacilityProviderModule

The physical name of a CMPI provider’s shared object library as it is stored in the hierarchical file system is

• libcmpiIBMzOS_CouplingFacilityProvider.so

string Caption

A short description of the class. Returns ‘IBM z/OS® Coupling Facility’.

string Description

A description of the class. Returns This is an IBM® z/OS Coupling Facility.

string ElementName

Name given to this instance of the class (same as Name)

datetime InstallDate

A datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.

string Name

Coupling Facility Logical Name as assigned by CFRM policy definitions.

Note: CF Name is not considered an immutable property of a Coupling Facility, since the name can be changed via a CFRM policy update. The physical CF information is the immutable identification information.

uint16 OperationalStatus [ ]

The current status of the CF (summarized from more granular CF state information):

0

Unknown

2

OK

6

Error

9

Stopping

string StatusDescriptions [ ]

Strings describing the various Operational Status values.

string Status

A string indicating the current status

uint16 EnabledState

Indicates the Enabled or Disabled state.

string OtherEnabledState

String describing the Enabled State value

uint16 RequestedState

The last requested State

uint16 EnabledDefault

Indicates the default value for Enabled State

datetime TimeOfLastStateChange

The date and time Enabled State was last changed.

uint64 IdentityToken [key]

The generated identity value for sysplex cluster. (Part 1 of 2)

string IdentityName [key]

The generated identity value for sysplex cluster. (Part 2 of 2)

string MachineType

Machine type of the server hosting the CF

string Manufacturer

Name of the manufacturer of the server hosting the CF

string ManufacturerPlant

The plant number where the machine was manufactured

string SerialNumber

A manufacturer assigned number to identify the server hosting the CF

uint8 LPARid

Platform-assigned ID of a logical partition in which the CF is running. Null if the Computer System is not virtualized

uint32 CFLevel

Facility operational (functionality) level

uint32 State

CF Operational State (summarized from more granular CF state information):

1

Okay

2

Unknown

6

Error

9

Stopping

uint16 NumberOfProcessors

Total number of CF processors

uint16 CPUUtilization

Percent CF processor utilization

uint32 FreeSpace

Currently unused storage available in the CF (in number of 4KB blocks)

uint32 TotalSpace

Total storage available in the CF (in number of 4KB blocks)

uint32 FreeDumpSpace

Currently unused allocated dump storage available in the CF (in number of 4KB blocks)

uint32 TotalDumpSpace

Total allocated dump storage available in the CF (in number of 4KB blocks)

uint32 StorageIncrementSize

Storage increment. The number of 4K blocks in a single storage increment in this CF.

boolean Standalone

Coupling Facility Standalone indicator:

TRUE

Not Standalone

FALSE

Standalone

boolean Volatile

Indicator of whether this CF is volatile or nonvolatile (based on battery backup or standby power source)

boolean CPUType

Indicates whether all of the CF processors are shared, or whether at least one is dedicated:

TRUE

All shared

FALSE

Some are dedicated

boolean MaintenanceMode

Indicates whether the CF is currently in Maintenance mode:

TRUE

Not in Maintenance mode

FALSE

CF is in Maintenance mode

boolean RecoveryMgrSite

TRUE

Recovery Manager is not active or the CF does not reside at the recovery site

FALSE

Recover Manager is active and the CF resides at the recovery site.

string SiteName

Name of the SITE specified in the CFRM policy.

string CPCID

Coupling Facility's Central Processor Complex (CPC) ID.

string CFCCReleaseLevel

The release level of the CFCC code.

string CFCCServiceLevel

The service level of the CFCC code.

datetime CFCCCodeBuildDate

The date and time that the CFCC code was built.

uint32 StartCFMaintenanceMode()

Sets the maintenance mode of the specified coupling facility to ON.

When a CF is in maintenance mode, the CF is not eligible for CF structure allocation purposes and all structure allocation processes will modify their CF selection processing accordingly.

uint32 StopCFMaintenanceMode()

Sets the maintenance mode of the specified coupling facility to OFF.

When a CF is no longer in maintenance mode, the CF is eligible for CF structure allocation purposes.
