Symptoms

The target of a snapped dataset is not usable by FDR.

 

An FDRABR restore of a VSAM file that was backup up using snap failed. No error messages are issued, FDRABR recatalogs the non-VSAM catalog entry for the cluster indicating that not all the expected pieces of a multi-volume KSDS cluster were found.

 

The following are the snap dataset statements that are generated.

SNAP DATASET  (SOURCE(AAAA.BBBBP.CCCCC)  -                    
 TARGET(XXXX.ZZZZ.**) DATACLAS(DATACLS1) -                         
 EXTENT_ALLOCATION(YES,CONSOLIDATE_ALL) RECALCULATE_FREESPACE(YES) -  
 DATAMOVER(ADRDSSU) REPLACE(Y) FORCE(N) HCPYMODE(SHR))                

 

Cause

The code was incorrectly calculating the extent count and updating the VTOC with incorrect information when a CONSOLIDATE was performed.

 

Resolution

Workaround:

  • Remove the "CONSOLIDATE" Parameter from the SNAP control statements.
