Explanation
In the message,
information is:
CONNECTION STATUS: {CONNECTED | NOT CONNECTED}
SYSTEM NAME: sysname
SYSTEM NUMBER: sysnum
IMAGE NAME: image
NETWORK ADDRESS: netid.nau
IPL TOKEN: ipltoken
DIAG INFO: diaginfo
The
message displays identification information associated with a system
in the sysplex, and the local system connection status to that system
for the purposes of employing the system status detection partitioning
protocol.
In the message text:
- CONNECTED
- The local system is connected to remote CPC image image through
BCPii callable services.
- NOT CONNECTED
- The local system is not connected to remote CPC image image through
BCPii callable services. The local system cannot target remote CPC
image image with the system status detection partitioning
protocol.
- sysname
- The name of the system in the sysplex that the remotely connected
status pertains to.
- sysnum
- The XCF system number assigned to the remote system sysname.
- image
- The image name associated with the remote system sysname in
the sysplex.
- netid
- The network ID of the local area network (LAN) connecting CPCs
on which the systems in the sysplex reside.
- nau
- The network addressable unit uniquely identifying an image as
a node on the LAN named by netid.
- ipltoken
- The IPL token assigned to system sysname in
the sysplex. The IPL token uniquely identifies the system instance
of sysname in the sysplex.
- diaginfo
- The diagnostic information applicable when the connection status
indicates that the local system is not connected to the remote system sysname and
CPC image image through BCPii callable services.
The diagnostic data returned by the BCPii callable service can help
determine the cause of the failed connection request. The diagnostic
information contains the following data:
- The name of the BCPii callable service that failed when the local
system attempted to establish a connection to another CPC or image
in the sysplex.
- An error return code that was returned by the BCPii callable service
that failed while the local system was attempting to establish a connection
to a CPC or image. See z/OS MVS Programming: Callable Services for High-Level Languages for
more information about BCPii services return codes and actions to
take in the event of a specific return code.
- A diagnostic data area returned by the BCPii callable service,
which contains information related to the BCPii service that failed.
System action
The system continues processing. If the system
status detection partitioning protocol cannot be used, the system
processes partitioning requests using a partitioning protocol based
on the sysplex failure management (SFM) policy or default indeterminate
status behavior. XCF will reattempt the failed request after a certain
time interval to allow for corrections to be made in the system environment.
Operator response
Notify the system programmer.
System programmer response
If the connection status is NOT CONNECTED,
see z/OS MVS Programming: Callable Services for High-Level Languages for
detailed information about return codes for BCPii callable services.
Determine the reason why the BCPii callable service shown in the diaginfo returned
an unsuccessful return code and make the appropriate corrections.
