DSNU030I csect-name UNABLE TO ALLOCATE dsn, RC=rr, CODE=ccc
Explanation
The utility was unable to allocate a necessary image copy data set. dsn is the data set name that the utility attempted to dynamically allocate. rr is the return code from the MVS™ dynamic allocation service, and ccc is the reason code associated with the return code.
System action
The utility proceeds along one or the following paths:
If the data set was an incremental image copy data set, the utility proceeds as if it and any later incremental image copies did not exist.
If the data set was a full image copy data set, the utility attempts to use the most recent prior full image copy data set.
If the data set is used by the COPYTOCOPY utility, and the utility job step includes an OPTIONS control statement with the EVENT(ITEMERROR,SKIP) option, COPYTOCOPY processes the next item in the list.
The allocation failure may create other problems that will cause the utility to fail. This is indicated by other messages.
System programmer response
If the utility fails because of the allocation error (as shown by a subsequent message), correct the error, then resubmit the job.
User response
If the job fails, contact the system programmer.
Problem determination
Refer to the appropriate MVS publication for a complete description of the possible return and reason codes from dynamic allocation.
