• CT group list (numeric): consistency group number (0x00 - 0x7F). For async
pairs you must specify this parameter. For sync pairs you must omit this
parameter.
• Priority list (numeric): priority of initial copy operation (1-256); default = 32.
• Fence level list (string): “N” or “Never” = never; “S” or “Status” = status;
“D” or “Data” = data; default = “Never”. For async pairs you must either
specify N (never) or omit this parameter.
• 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.
Figure B.1 shows an example of the pair macro commands needed to create
the specified pairs with the parameters listed in Table B.7.
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).
