Explanation
The CF request time ordering function is enabled
for operations to the coupling facility or the CF request time ordering
function is not enabled and not required. The coupling facility is
identified by the node descriptor. See mapping IXLYNDE.
In the
message text,
text1 is:
- REQUIRED AND ENABLED
- The CF request time ordering is required for operations to the
coupling facility. The required hardware (CF request time ordering
function installed on both the CECs where the CF and z/OS® systems are running) is available. The CF and z/OS system
are synchronized in the same timing network.
- NOT-REQUIRED AND ENABLED
- The CF request time ordering is not required for operations to
the coupling facility. The required hardware (CF request time ordering
function installed on both the CECs where the CF and z/OS systems are running) is available. The CF and z/OS system
are synchronized in the same timing network.
- NOT-REQUIRED AND NOT-ENABLED
- The CF request time ordering is not required for
operations to the coupling facility. The CF request time ordering
function is not enabled: either the required hardware (CF request
time ordering function installed on both the CECs where the CF and z/OS systems are running) is not
available, or the CF and z/OS system are not synchronized in the same
timing network.
In the message text,
text2 is:
COUPLING FACILITY type.mfg.plant.sequence
PARTITION: partition side CPCID: cpcid
In
the message text:
- type
- Node type (See ndetype in IXLYNDE).
- mfg
- Node manufacturer ID (See ndemfg in IXLYNDE).
- plant
- Node manufacturer plant ID (See ndeplant in IXLYNDE).
- sequence
- Node sequence number (See ndesequence in IXLYNDE).
- partition
- Node LPAR partition number (See ndepartition in IXLYNDE).
- side
- The node PP/SI mode indicator and configuration code from the
IXLYNDE are used to determine the value for side.
Value and meaning are:
- SIDE: 0 means the coupling facility is on SIDE 0 of a partitionable
CPC.
- SIDE: 1 means the coupling facility is on SIDE 1 of a partitionable
CPC.
- blank means the coupling facility is in a non-partitionable CPC.
- cpcid
- Node Central Processor Complex (CPC) ID (See ndecpcid in IXLYNDE).
System action
The system will request CF request time ordering
function to be executed on each operation to the coupling facility
if it is enabled. The system will not request CF request time ordering
if the function is not enabled
