4.3 Changing Remote Copy Mode for a Volume Group
Use the setrcopygroup mode command to change the Remote Copy mode of a volume
group. This allows you to convert a synchronous volume group to an asynchronous periodic
volume group or vice versa.
Follow these steps to change the Remote Copy mode for an existing volume group.
1 Stop the primary group, leaving the resynchronization snapshots on the system.
2 Change the Remote Copy mode of the volume group as follows:
◆ is the new Remote Copy mode ( sync or periodic ).
◆ is the name of the target name for the volume group.
◆ is the name of the Remote Copy volume group.
3 Start the primary volume group as follows:
4 If converting a synchronous volume group to an asynchronous periodic volume group, set
the synchronization period using the following command:
where is the new resynchronization period followed by s to denote seconds, m to
denote minutes, h to denote hours, or d to denote days.
NOTE: Only one mode (synchronous or asynchronous periodic) per target is
allowed.
