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:
◆
<mode_value>
is the new Remote Copy mode (
sync
or
periodic
).
◆
<target_name>
is the name of the target name for the volume group.
◆
<group_name>
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
<value>
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.
