Parameter Description
Synchronization Method Mode of data synchronization for the
consistency group. This parameter is
displayed only when Replication Mode is
set to Asynchronous. The values include:
l Manual: Data synchronization needs to
be performed manually.
l Timed wait after synchronization
begins: The system starts timing as soon
as the latest synchronization begins.
When the time specified in Interval has
elapsed, the system automatically starts
to synchronize data between the primary
resource and secondary resource again.
NOTE
If the latest synchronization is still being
executed after the time specified in Interval
has elapsed, the data synchronization will
start after the latest synchronization finishes.
l Timed wait after synchronization
ends: The system starts timing as soon
as a synchronization operation is
completed. When the time indicated by
Interval has elapsed, the system starts
synchronizing data again.
Interval
Waiting time for the two synchronization
methods, Timed wait after
synchronization begins and Timed wait
after synchronization ends.
NOTE
When the primary-end model is 2200 V3, the
resource type is LUN, the unit can only be
minutes and the interval is an integer ranging
from 15 to 1440 (inclusive).
Data Transmission During data synchronization for the
consistency group, data is compressed or
not. If it is data compression transmission,
replication links are with lower bandwidth
pressure, while improving the replication
performance. The values include:
l Compression
l No compression
NOTE
This parameter is available when Replication
Mode is set to Asynchronous.
