• CFW flag list (numeric): 0 = copy CFW data to R-VOL; 1 = only M-VOL; default = 1.
• DFW flag list (numeric): 0 = DFW not required; 1 = DFW required; default = 0. Must be
omitted for async pairs.
• Error level list (string): “G” = group; “V” = volume; default = G. For sync pairs you must omit
this parameter.
• Time-Saving Mode flag: “Yes” = The Use Time-Saving Mode option is enabled;
“No” = The Use Time-Saving Mode option is disabled; default = “Yes”. This parameter is a
non-list type and only one value can be specified.
• Differential management measurement flag list (string): The differential between the volumes
is managed in cylinder (“Cylinder” or “C”) or in track (“Track” or “T”). When “Auto” or “A”
is specified, the storage system selects the differential management measurement (cylinder or
track) automatically. The default is Auto.
• Time stamp transfer list (string): “Enable” = The host I/O time stamp is transferred from M-VOL
to R-VOL; “Disable” = The host I/O time stamp is not transferred from M-VOL to R-VOL; default
= “Disable”. For the async pairs you must omit this parameter.
“CreateHrcPair Command” (page 232) shows an example of the pair macro commands needed to
create the specified pairs with the parameters listed in “CreateHrcPair Parameters” (page 231).
CAUTION: When using the CreateHrcPair command to create more than one pair, make sure
to keep each line within the maximum line length (320 bytes).
