REVERSE
Applies to Continuous Access Synchronous for Mainframe, Continuous Access Asynchronous for
Mainframe, and Continuous Access Journal for Mainframe.
When the copy direction is forward
When the copy direction is reverse
When neither FORWARD parameter nor REVERSE parameter are specified, the status of copy pairs
become SUSPOP. The copy direction is not changed at the time of RESYNC.
SVOL ({PROTECT|PERMIT})
Specify whether writing to the S-VOL is permitted or protected after a volume is suspended (SUSPOP).
When this parameter is not specified, the value specified in the ISPF panel is assumed. If the
ATTIME parameter or CANCEL parameter are both specified, this specification is disregarded,
and the write permissions for the S-VOL during the suspend are canged as follows, depending on
the copy type:
Copy type
Business Copy for Mainframe
Continuous Access Asynchronous for
Mainframe
PROTECT
This value means that writing to the S-VOL is protected after a volume is suspended (SUSPOP).
PERMIT
This value means that writing to the S-VOL is permitted after a volume is suspended (SUSPOP).
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.
after RESYNC. If this parameter is specified for Continuous
Access Asynchronous for Mainframe or Continuous Access
Journal for Mainframe, the data synchronization method
during the suspension will be the same as that used when
the FLUSH parameter is specified.
Places copy pairs in the SWAPPING status, so that the copy
direction goes from the secondary site to the primary site
after RESYNC. If this parameter is specified for Continuous
Access Asynchronous for Mainframe or Continuous Access
Journal for Mainframe, the data synchronization method
during the suspension will be the same as that used when
the FLUSH parameter is specified.
Places copy pairs in the SUSPOP status, so that the copy
direction goes from the secondary site to the primary site
after RESYNC. If this parameter is specified for Continuous
Access Asynchronous for Mainframe, the data
synchronization method during the suspension will be the
same as that used when the DRAIN parameter is specified.
If this parameter is specified for Continuous Access Journal
for Mainframe, the data synchronization method during the
suspension will be the same as that used when the FLUSH
parameter is specified.
