NOCOPY
no matter whether you specify COPY or NOCOPY
for the MODE parameter, the storage system
recognizes it as COPY mode. Therefore, initial
full-volume copy will be performed.
1 Copy speed will be slow, except when the DKC
emulation type is 2105 or 2107. When the DKC
emulation type is 2105 or 2107, the copy speed
is always medium regardless what you specify
for the PACE parameter.
PACE
other than 1 Copy speed will be medium.
CRIT Not applicable. SIz does not use this parameter. Siz ignores it.
MSGREQ YES
NO
If you specify this parameter when MODE(RESYNC)
is set, the command ends abnormally by reporting
CC = 12. So, please do not specify this parameter
when MODE(RESYNC) is set.
LSS Primary volume CU number
*1
, or secondary
volume CU number
*1
.
ONLINSEC

YES
Pair create operation will be performed whether the
T-VOL is online or not.
NO Pair create operation will not be performed if the
T-VOL is online.
*Note 1: CU number or the parameter is valid only for the DKC emulation
type 2105 or 2107.
*Note 2: When you do not specify the parameter, the result is same as when
you specify NO for this parameter.
