Suspend Pairs
The SuspendHrcPair command allows you to suspend TCz pairs. The
SuspendHrcPair parameters include:
• Device list (numeric): L x 0x10000 + C x 0x100 + VV, where L=LDKC#,
C=CU#, VV=vol# within the CU.
Note: When you write 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.
• Suspend mode list (string): “M” or “M-Vol” = M-VOL failure, “R” or “R-Vol” =
R-VOL; default = R-VOL. You must specify R or omit this parameter when
suspending async pairs.
• Flag list (numeric): suspend report flag: 0 = reports; 1 = no reports; default
= 1.
• Suspend range list (string): “G” or “Group” = group; “V” or “Volume” =
volume. For sync pairs you must omit this parameter.
– When one volume is specified, the default = G. If you want to suspend
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.
• Pending data flag list (string): “D” or “Drain” = drain; “P” or “Purge” =
purge; default = D. 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.
