Change Pair Options
The ChangeHrcOption command allows you to change the pair options for TCz
pairs. The ChangeHrcOption parameters include:
• M-VOL device list (numeric): L x 0x10000 + C x 0x100 + VV, where
L=LDKC#, C=CU#, VV=vol# within CU.
Note: When you write M-VOL device list, you can omit LDKC# if the
LDKC# is 0. For example, You can write 0x0102 when LDKC# is 0, CU# is
1, and vol# is 2.
• Fence level list (string): “N” or “Never” = never, “S” or “Status” = status;
“D” or “Data” = data; default = current value. For async pairs you must
either specify N or omit this parameter.
• CFW flag list (numeric): 0 = copy CFW data to R-VOL; 1 = only M-VOL;
default = current value.
• DFW flag list (numeric): DFW flag list is only left to maintain the
compatibility of the format. The specification is not available.
• Error level list (string): “G” = group; “V” = volume; default = current value.
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.
