Explanation
XCF is removing a system from the sysplex.
In
the message text:
- sysname
- The name of the system XCF is removing from the sysplex.
- jobname
- The name of the job that requested the sysplex partition.
- reason
- The reason the system is being removed from the sysplex:
- LOSS OF COUPLE DATA SET
- System sysname could not function in the sysplex
because of failure(s) of the primary and alternate (if available)
couple data set.
- LOSS OF CONNECTIVITY
- XCF initiated a request to remove system sysname from
the sysplex because it lost signalling connectivity to one or more
other systems in the sysplex.
- OPERATOR VARY REQUEST
- An operator requested that system sysname be
removed from the sysplex.
- SYSTEM STATUS UPDATE MISSING
- XCF initiated a request to remove system sysname from
the sysplex because XCF detected missing system status updates for sysname.
This indicates that the system may have failed.
- LOSS OF ETR
- An operator requested that sysname be removed
from the sysplex because it lost access to the external time reference
(ETR).
- SYSTEM ENTERED WAIT STATE
- System sysname entered a wait state, either initiated by IXCPART or detected by XCF.
- SYSTEM DETECTED AS NO LONGER IN SYSPLEX
- System sysname was removed from the sysplex.
XCF could not determine the reason.
- POLICY INITIATED REQUEST
- XCF processor resource/systems manager (PR/SM™) policy initiated the request to remove
the system from the sysplex or the system is PR/SM capable and RESETTIME or
DEACTTIME was specified in the SFM policy.
- SFM STARTED DUE TO STATUS UPDATE MISSING
- System sysname was removed from the sysplex
as required by the sysplex failure management policy because the system
was not updating its status at regular intervals.
- SFM INITIATED DUE TO SIGNALLING FAILURE
- System sysname was removed from the sysplex
as required by the sysplex failure management policy because the sysplex
had to be reconfigured in order to resolve a signalling connectivity
failure in the sysplex.
- A NEW SYSTEM IS DETECTED RUNNING ON THE SAME CPC
- System sysname was removed from the sysplex
because it was determined that another MVS™ system
was running on the same CPC image which system sysname was
previously running.
- INCOMPATIBLE LOGICAL PARTITION NUMBER
- System sysname was removed from the sysplex
because it was determined that it could not support the logical partition
number of another system in the sysplex.
- TIMING NOT SYNCHRONIZED WITH SYSPLEX
- System sysname was removed from the sysplex
because it was determined that it was not synchronized to the same
time reference as the other systems in the sysplex.
- SYSTEM CAUSING SYMPATHY SICKNESS
- The system was removed from the sysplex to alleviate sympathy
sickness that was impacting other systems in the sysplex. Message
IXC440E might have been issued by the impacted systems. Message IXC631I
might have been issued by the removed system to indicate which stalled
XCF members were causing the sympathy sickness.
- SYSTEM RESET OR NEW IMAGE LOADED
- The partition containing system sysname has
been reset, deactivated, or a new system image has been loaded in
the partition that it formerly occupied.
- CPC FAILURE
- The central processing complex (CPC) on which the system was running
has failed.
- PARTITION DEACTIVATED
- The central processing complex (CPC) LPAR on which the system sysname was
running has been deactivated.
- SYSTEM HAS AN IMPAIRED CRITICAL MEMBER
- The system was removed from the sysplex to alleviate a critical
member impairment condition that could have been impacting other systems
in the sysplex. Message IXC633I and message IXC636I may have been
issued by the removed system to indicate which impaired XCF members
were causing the impairment condition.
- OPERATOR VARY REQUEST WITH REIPL OPTION
- An operator requested that system sysname be
removed from the sysplex and the system be re-IPLed by the AutoIPL
function.
- OPERATOR VARY REQUEST WITH SADMP OPTION
- An operator requested that system sysname be
removed from the sysplex and that stand-alone dump (SADMP) be IPLed
for this system by the AutoIPL function.
- OPERATOR VARY REQUEST WITH SADMP AND REIPL OPTIONS
- An operator requested that system sysname be
removed from the sysplex and that stand-alone dump (SADMP) be IPLed
for this system by the AutoIPL function, followed by MVS being re-IPLed by SADMP.
System action
The system continues processing without the removed
system.
Operator response
If the system programmer requests it, obtain
a stand-alone dump.
System programmer response
Look for and correct any problems
with the ETR clock, signalling paths, or couple data set.
If
the system was removed because it could not support the logical partition
number of another system, look for and correct the missing service
that will allow the system to support the attributes of the other
systems in the sysplex.
If the problem persists, search problem
reporting data bases for a fix for the problem. If no fix exists,
contact the IBM® Support Center.
Provide the stand-alone dump.
