CF request time ordering is required for operations to this coupling facility; however the timing characteristics of the coupling facility are not consistent with timing characteristics of the z/OS® system. The coupling facility is identified by the node descriptor. See mapping macro IXLYNDE. The reason why that CF request time ordering will not be enabled is described 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 that the coupling facility is on SIDE 0 of a partitionable CPC.
• SIDE: 1 means that the coupling facility is on SIDE 1 of a partitionable CPC.
• Blank means that the coupling facility is in a non-partitionable CPC.

cpcid

Node Central Processor Complex (CPC) ID (See ndecpcid in IXLYNDE).

reason

reason is one of the following:

REASON: CTNID MISMATCH - CF CTNID: cfstpid-cfetrid

The CF request time ordering function is required for operations to the CF; however, the CTNID that is defined for the CEC that is running the CF does not match the CTNID that is defined for the CEC that is running the z/OS system. The cfstpid is the eight-byte STP portion of the CTNID that has been defined for the CEC running the CF. The cfetrid is the ETR Network ID of the ETR that is connected to the Coupling Facility.

Issue D ETR to obtain CTN information for the CEC running the z/OS system.
