DDRREC
DDRREC is used in the SVC 76-initiated error recording process for type 60 DlSD dump
restore (DDR) dynamic device reallocation records. The reallocation records contain the replacement of the virtual "FROM" and "TO" control unit addresses (COA) by the real
addresses of the real DlSD devices. 0 8 10 18 20 28 30 38
