Explanation
The job has defined an old checkpoint data set
with the DD statement, on the volume, mounted on the device.
In
the message text: jjj
The job name.
ddname
The DD name on the DD statement.
utn
The device number of the specified device.
ser
The volume serial number.

System action
The system waits for the operator to reply. When
the reply is ‘NO’, processing continues with the indicated
volume, making it a non-secure volume. When the reply is ‘YES’
and the original request was for a specific volume, processing continues
with the indicated volume. If the original mount request was for a
scratch volume, another MOUNT SCRATCH request is issued by the system.

Operator response
Make sure that the volume identified in the
message text is known to be a secure checkpoint volume. This may be
accomplished by inspecting the volume for a special checkpoint label.
