If CA Disk abends during move processing, the source data set is still recovered to its original state. This capability is provided by a recovery facility executed in the AMSSORT and AMDSEXEC steps of the DMS procedure. These steps are only executed in the event of an abend during the move process.
The AMSRFILE dd statement provides input to these two steps. The AMSEXEC step will rename any data set left in a suspended state due to an abend based on the information provided by AMSRFILE. By default, the disposition of the AMSRFILE is a temporary data set.
If a system IPL or a S222 abend occurs, you would have to manually locate the name of the source and target data sets, delete the target and alter the source back to the original name. To assist you in locating these data sets, CA Disk issues informational message 4017. Or you can simplify the cleanup process by creating a GDG data set to use for the AMSRFILE dd statement. This will allow the AMSRFILE to remain after an IPL or job cancel, and will provide you with the data set name to be renamed as well as the target data set name to be deleted during your manual cleanup.
