Explanation
A dump of the named coupling facility (CF) has
been initiated to capture diagnostic data.
In the message text:
- dumptype
- One of the following:
- DISRUPTIVE
- The coupling facility took a disruptive dump, resulting in failure
of the CF. All systems observe a loss of connectivity to the CF.
- NON-DISRUPTIVE
- The coupling facility took a non-disruptive dump. The CF continues
operating.
- cfname
- Name of the affected coupling facility.
- 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).
- requestor
- One of the following:
- SYSTEM
- z/OS® requested that the
CF initiate a dump.
- CF
- The coupling facility initiated the dump.
- OPERATOR
- The operator requested the CF dump via SETXCF DUMPCF.
- strname
- Name of the structure associated with the problem for which the
CF is being dumped. A value of N/A indicates that the system
could not determine the structure name. Present only when requestor is SYSTEM.
- sid
- Structure ID of the structure associated with the problem for
which the CF is being dumped. Present only when requestor is SYSTEM.
- diagdata
- Diagnostic data to assist IBM® personnel
in determining the reason for the dump. Present only when requestor is SYSTEM or OPERATOR.
System action
If requestor is SYSTEM,
the system initiates an SDUMP to document its perception of the error.
If the system determines that a structure can no longer be used as
a result of the error, it initiates processing to stop using the affected
structure. If dumptype is DISRUPTIVE, all systems
recognize a loss of connectivity to the affected CF.
Operator response
Notify the system programmer.
System programmer response
Capture the CF dump and, if applicable,
the z/OS dump, and contact IBM. Once the CF dump has been
captured, you can delete message IXL051E from the Action Message Retention
Facility (AMRF) (if in use) by issuing the K C,E,id command,
where id is the message ID associated with IXL051E.
