Explanation: NOCOPYPOOLBACKUP is an optional parameter that indicates an alternate return code value for failed data set recovery requests.
If you specify a partially qualified data set name on DSNAME and the copy pool backup version cannot be found for a data set that matches the filtering criteria, the default return code is eight. In this case, however, you might not expect all of the data sets to be found in a copy pool backup version. If so, you can specify NOCOPYPOOLBACKUP(RC4) to have a lower return code for this situation (return code four instead of eight).
NOCOPYPOOLBACKUP is valid with DSNAME only. It is not valid with the COPYPOOL or TOVOLUME parameters.
Defaults: RC8.
