Resynchronize Pairs
The ResumeHrcPair command allows you to resynchronize TCz pairs. The
ResumeHrcPair 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.
Priority list (numeric): priority of initial copy operation (numeric 0-256);
default = current value.
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 (never) or omit this parameter.
Sync level list (string): “S0” or “Synchronous0” = sync, “S2” or
“Synchronous2” = async; default = current value.
Error level list (string): “G” or “Group” = group; “V” or “Volume” = volume;
default = current value. For sync pairs you must omit this parameter.
Resynchronize range list (string): “G” = group; “V” = volume. For sync pairs
you must omit this parameter.
When one volume is specified, the default = G. If you want to
resynchronize only one async pair, you must specify V.
When two or more volumes are specified, the default = V. When two or
more volumes are specified, you must either specify V or 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.
