Specify the copy mode.
QUICK
Transit to the DUPLEX status quickly.
NORMAL
Transit to the DUPLEX status after copy completion.
{FORWARD|REVERSE}
Specify the copy direction.
Based on the information updated since transiting to the SUSPOP status, the differences are copied
for tracks and cylinders, and the DUPLEX status is recovered.
When the parameter is not specified in BC, the differences are copied from P-VOL to S-VOL.
When the parameter is not specified in CA, CAA, or CAJ, the differences of the copy pairs in the
SUSPOP status are copied.
A copy pair with the S-VOL SWAP status is not copied. Even for RESYNC, the direction of the copy
does not change.
FORWARD
In BC, the difference is copied from P-VOL to S-VOL.
In CA or CAA, or CAJ, the difference is copied from the primary site to the secondary site.
REVERSE
In BC, the difference is copied from S-VOL to P-VOL.
In CA or CAA, or CAJ, the difference is copied from the secondary site to the primary site.
DEVN(p-vol-device-number,s-vol-device-number) ~ <4-digit hexadecimal number, 4-digit
hexadecimal number>
Specify the device number of the copy pair (P-VOL and S-VOL) to operate. If you specify this
parameter after ATTIME suspend, execute the YKSUSPND command with the CANCEL parameter
specified.
VOLUNIT
When this is specified, the operation is performed by volume even when the environment supports
operation by group. If you specify this parameter after ATTIME suspend, execute the YKSUSPND
command with the CANCEL parameter specified.
The following describes the relationship between the VOLUNIT parameter specification and the
command execution when issuing the YKRESYNC command to reverse the copy direction.
When the VOLUNIT parameter is not specified:
The command is executed only when the copy pair status is SWAPPING.
When the VOLUNIT parameter is specified:
The command is executed even if the copy pair status is not SWAPPING.
NOTE:
Usually, to operate by volume only those copy pairs whose statuses do not match due to
reasons such as a failure, specify the CANCEL parameter together with the SELECT(COND)
parameter.
