Explanation
 VTAM® issues
this message when it is stopping the rebuild of the coupling  facility
structure for any of the following  reasons:  Lost connection to new structure 
Lost connection to original structure    
Structure failure 

 This message is the first of a group of messages.
A description of the message  group follows.   IST2163I REBUILD FOR STRUCTURE structure STOPPED
[IST2164I FAILURE REASON - LOST CONNECTION TO NEW STRUCTURE]
[IST2165I FAILURE REASON - LOST CONNECTION TO ORIGINAL STRUCTURE]
[IST2166I FAILURE REASON - STRUCTURE FAILURE]
 IST314I END

 IST2163I  In the message text: structure
The name of the coupling facility structure. 

 IST2164I  The rebuild failed because VTAM lost
connectivity to the new structure.

 IST2165I  The rebuild failed because VTAM lost
connectivity to the original structure.

 IST2166I  The rebuild failed because VTAM received
a Structure Failure Event in the Coupling Facility Event  Exit. The
coupling facility detected a problem.

System action
  IST2164I
VTAM continues to use the
original structure. Processing continues.
IST2165I
As long as one VTAM in
the group is connected to the original structure, rebuild continues
from the connected VTAM. Processing
continues on the new structure for the VTAM that
lost connectivity to the original structure.
IST2166I
The structure rebuild stops. VTAM might
continue with a local repopulation of the new structure or continue
processing on the original structure depending on which structure
failed.

Operator response
   IST2164I
Save the system log for problem determination.  Use the VARY CFS
command to connect VTAM to
the new structure when the problem is corrected. See the VARY CFS command in z/OS Communications Server: SNA Operation for a description of the VARY CFS command.
If you cannot resolve the problem, contact the system programmer.
IST2165I
Save the system log for problem determination. If you cannot resolve
the problem, contact the system programmer.
IST2166I
Save the system log for problem determination. Make sure that
all VTAMs in the sysplex have        connectivity to the coupling
facility. You can try a rebuild again by issuing the SETXCF      
 START, REBUILD command. See the SETXCF command in
        z/OS MVS System Commands for
a description of the        SETXCF command. 

System programmer response
 Review the system log for problem
determination.
