Copy pair

status

Yes

Copying 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/A

Yes

Differential 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.

Yes

N/A

The 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/A

Yes

Differential copy
(resynchronization) is being

REVRSY

performed from the S-VOL to the
