Programmer response
 If a RECOVER command
was issued, determine if a DFSMShsm incremental backup version exists
for the data set by using the LIST or HLIST command. If a DFSMShsm incremental
backup version does exist and it is recent enough, issue the RECOVER
or HRECOVER command specifying which backup version you want.
 If an FRRECOV command was issued, determine and resolve
the cause of the error and reissue the command. 
 DFSMShsm routes
the DFSMSdss messages
to the user or the dump activity log. See z/OS MVS System Messages, Vol 1 (ABA-AOM) for
an explanation of any accompanying DFSMSdss messages. DFSMSdss message numbers are
prefixed with ADR.
