status
YesYesYesYesCopying of differential update
data is being performed to
TRANS
ensure that the volume status
can be changed to SUSPOP or
SIMPLEX.
NOTE: In this status, copy pair
dissolving is not allowed
because the data is not
guaranteed.
N/AN/AN/AYesDifferential update data is being
copied to the S-VOL in the
SUSPVS
background by the YKSUSPND
command with the QUICK
parameter specified.
NOTE: In this status, copy pair
dissolving is not allowed.
YesYesYesN/AThe relationship between P-VOLs
and S-VOLs are reversed by the
SWAPPING
YKSUSPND command (the
FORWARD/REVERSE parameter
specification). The actual
swapping takes place at the
execution of the YKRESYNC
command.
Also, for a 2DC configuration
with HyperSwap and Cnt Ac-J
Z, this indicates that the
relationship between the P-VOL
and S-VOL has reversed to the
suspend status due to a
HyperSwap. Note that a change
to this status by HyperSwap is
only for Cnt-Ac S Z with the
HyperSwap attribute.
N/AN/AN/AYesDifferential copy
(resynchronization) is being
REVRSY
performed from the S-VOL to the
P-VOL by the YKRESYNC
command (with the REVERSE
