OA41693: XRC EXCESSIVE ANTX5132W MESSAGES WITH RC=1009 DUE TO TIMEOUT

APAR status

• Closed as fixed if next.

Error description

• Client receives the following XRC message(s) without a suspend
  to the mirror:
  
   ANTX5132W XRC SESSION(session) ENCOUNTERED AN ERROR REPLICATING
   A BITMAP OPERATION FROM PRIMARY VOLUME(volume) TO SWAP
   VOLUME(####) RC=1009 REAS=0000
  
  Additional message symptoms:
   ANTX8149I SESSION(session) XSWAP MAY REQUIRE FULL RESYNC OF
   VOLUME PAIR(privol,secvol) RC=4510 REAS=0
   ANTX5131W XSWAP OPERATION ON XRC SESSION(session) MAY REQUIRE
   FULL RESYNCHRONIZATION FOR 1 VOLUMES
  
  GDPS message symptom:
   GEO364W XRC SYSTEM IS NOT READY FOR INCREMENTAL RESYNC, RC= 8
  
  In this client's case, the MiscLow XRC environmental parameter
  may be set too low for the query responses to the storage
  subsystem.
  

Local fix

• Raise the MiscLow value higher than the default setting of 2 if
  channel extenders are being used.
