Explanation
A couple data set failed. XCF is removing it from
the sysplex.
Each system affected by the failure
of the couple data set issues IXC253I to report its removal. The
system detecting the error may also issue the ERROR CASE line(s) to
provide additional detail about the failure.
In the message
text:
- PRIMARY
- XCF is removing the primary couple data set from the sysplex.
- ALTERNATE
- XCF is removing the alternate couple data set from the sysplex.
- dsname
- The name of the couple data set that XCF is removing from the
sysplex.
- typename
- The type of data contained in the data set.
- errortype
- One of the following:
- AN UNKNOWN ERROR
- An error that cannot be determined.
- AN I/O ERROR
- I/O error on the couple data set.
- INCONSISTENT INFORMATION
- Inconsistent information in the couple data set.
- A SETXCF COUPLE,PSWITCH OPERATOR COMMAND
- Initiated by operator command SETXCF,COUPLE with the PSWITCH option.
- A SETXCF COUPLE,ACOUPLE OPERATOR COMMAND
- Initiated by operator command SETXCF,COUPLE with the ACOUPLE option.
- sysname
- The name of the system that initiated the request or detected
the error.
- errorcase
- One of the following:
- PERMANENT ERROR
- An I/O operation has failed with a permanent I/O error.
- UNRESOLVED I/O TIMEOUT
- Attempts to initiate I/O have timed out repeatedly, and the system
has been unable to complete an I/O request within the 5 minute retry
period.
- TAKEOVER BY ANOTHER SYSPLEX
- Another sysplex has taken ownership of the couple data set because
the operator incorrectly replied 'U' to IXC248E / IXC247D while the
couple data set was still in use by the sysplex of which the issuing
system is a member.
- UNABLE TO IDENTIFY WRITING SYSTEM
- The system that left the couple data set partially written did
not record its identity before beginning the write. The writing system
may not have the partial write recovery support introduced by APAR
OW51741 or z/OS® V1R5.
- WRITING SYSTEM NO LONGER ACTIVE
- The system that left the couple data set partially written was
partitioned from the sysplex before it could complete the repair of
the affected record.
- TIME LIMIT FOR REPAIR EXPIRED
- The maximum time limit for repair of a partially written record
has elapsed.
- stealsys
- The name of the system from which the operator replied to IXC247D
to allow ownership of the couple data set to be taken over.
- stealtime
- The date/time when ownership of the couple data set was taken
over, in the format mm/dd/yyyy hh:mm:ss.ffffff.
System action
The system stops using the couple data set.
If
the failing couple data set was the primary, XCF tries to switch to
the alternate couple data set. Any work in progress will be restarted
once the switch is made. If no alternate couple
data set is available, the function associated with this couple data
set type becomes unavailable. If the affected couple data set is
sysplex or CFRM, XCF removes the issuing system from the sysplex.
If
the failing couple data set was the alternate, the alternate becomes
unusable. XCF informs all other systems in the sysplex of the failure.
Operator response
If the reason for the couple data set removal
was:
- AN I/O ERROR with error case PERMANENT ERROR
- INCONSISTENT INFORMATION
then dump the couple data set. See the operator response
to message IXC220W for the correct JCL to dump the couple data set.
Otherwise, notify the system programmer.
System programmer response
Allocate and format
a new alternate couple data set. Ask the operator to enter the SETXCF
COUPLE,ACOUPLE command to make the new alternate couple data set available
to XCF. The command should only be entered on one system in the sysplex.
