Settings for remote copy mode are specified using the remote copy parameters. The remote copy parameters are COPY-MODE, ON-ERROR and PENDING-UPDATES.
You can set the COPY-MODE and ON-ERROR remote copy parameters using the /MODIFY-REMOTE-COPY-PARAMETER command. The PENDING-UPDATES parameter is always set on the storage system with the target unit. If an error occurs, the ON-ERROR and PENDING-UPDATES remote copy parameters have a considerable impact on the availability of the source and target units (see section "ON-ERROR" and section "PENDING-UPDATES").
/SHOW-REMOTE-COPY-STATUS displays the values of the ON-ERROR parameter in a separate column. The internal storage system parameter PENDING-UPDATES is displayed in the two-part column PEND-UPD-ON-TARGET. The ALLOW column indicates whether or not PENDING-UPDATES are permitted. The CURR-SIZE column indicates the current size of outstanding writes to the target unit.
