Description
Re-establish a split or suspended volume pair.
This parameter is required.
Copy speed of resynchronization 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 of
resynchronization is always medium regardless
what you specify for the PACE parameter.
Copy speed of resynchronization will be
medium.
SIz does not use this parameter. SIz ignores it.
MSGREQ function is applicable.
For a Resync request on all pairs in a CTG, do
not use the MSGREQ function. If you use the
MSGREQ function, the job will end abnormally
and CC = 8 will be reported.
MSGREQ function is not applicable.
Pair resynchronize operation (forward) will be
performed whether the T-VOL is online or not.
Pair resynchronize operation (backward) will
be performed whether the S-VOL and T-VOL
are online or not.
Pair resynchronize operation (forward) will not
be performed if the T-VOL is online.
Pair resynchronize operation (backward) will
not be performed if the S-VOL and T-VOL are
online.
