Differential update data is being copied
to the S-VOL in the background by the
SUSPVS
YKSUSPND
command with the QUICK
parameter specified.
NOTE:
In this status, copy pair
dissolving is not allowed.
Yes
Yes
Yes
N/A
The relationship between P-VOLs and
S-VOLs are reversed by the YKSUSPND
SWAPPING
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.
