Release Pairs
The DeleteHrcPair command allows you to release TCz pairs. The DeleteHrcPair
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.
• Release mode list (numeric): 0 (0x00) = normal, 1 (0x01) = release by
force; default = 0. You must specify 0 (normal) when releasing two or more
async pairs.
• Release range list (string): “G” or “Group” = group; “V” or “Volume” =
volume; “C” or “C/T” = consistency time. For sync pairs you must omit this
parameter.
– When two or more volumes are specified, the default = V. If you want to
release two or more specific async pairs, you can specify V or omit this
parameter.
– When one volume is specified, the default = G under these conditions:
Volume is an M-VOL and release mode = 0 (normal) (any pair status); or
Volume is an R-VOL, release mode = 0, and pair status = Suspending or
Deleting.
If you want to release an entire group by force (release mode = 1), you
must specify G.
– When one volume is specified, the default = C/T under these conditions:
Volume is an R-VOL, release mode = 0, and pair status is not Suspending
or Deleting.
• 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.
