1. Click Volumes. 2. Expand Volumes and then select the volume. 3. In the Activities panel, click Pause SyncRep. When prompted, confirm the action. While synchronous replication is paused: • The volume's SyncRep status in the General Volume Information panel indicates that it is paused. • If any data is written to the volume while synchronous replication is paused, the writes are tracked. The tracked changes are written to the SyncAlternate volume when synchronous replication is resumed. • If you pause synchronous replication for a single volume in a synchronous replication collection, the synchronous replication status of the paused volume is paused, and the other volumes in the collection are shown as being out of sync, even though data is still written to their active and alternate pools. The system brings the collection back in sync after synchronous replication is resumed for all volumes. Resume Synchronous Replication (SyncRep) To resume synchronous replication (SyncRep) after it has been paused: 1. Click Volumes. 2. Expand Volumes and then select the volume. 3. In the Activities panel, click Resume SyncRep. After synchronous replication has been resumed: • The group copies to the SyncAlternate volume any changes that were made while synchronous replication was paused. • The volume's SyncRep status in the General Volume Information panel indicates that the volume is out of sync until all outstanding writes have been committed to the SyncAlternate volume. When all writes have been committed, the status changes to in sync. Enable Synchronous Replication (SyncRep) for a Volume Collection To enable synchronous replication (SyncRep) for a volume collection, all volumes in the collection must: • Have synchronous replication enabled • Be in sync • Use the same two storage pools • Not belong to another SyncRep collection • Not be moving from one pool to another To enable SyncRep for a volume collection: 1. Click Volumes. 2. Expand Volume Collections and then select the collection from the list. 3. In the Activities panel, click Enable SyncRep for collection. Disable Synchronous Replication (SyncRep) for a Volume Collection To disable synchronous replication (SyncRep) for a collection: 1. Click Volumes. 2. Expand Volume Collections and then select a collection from the list 3. In the Activities panel, click Disable SyncRep for collection. 308 About Synchronous Replication

2.
Expand
Volumes
and then select the volume.
3.
In the Activities panel, click
Pause SyncRep
.
When prompted,
confirm
the action.
While synchronous replication is paused:
•
The volume’s SyncRep status in the General Volume Information panel indicates that it is paused.
•
If any data is written to the volume while synchronous replication is paused, the writes are tracked. The tracked changes are
written to the SyncAlternate volume when synchronous replication is resumed.
•
If you pause synchronous replication for a single volume in a synchronous replication collection, the synchronous replication
status of the paused volume is paused, and the other volumes in the collection are shown as being out of sync, even though data
is still written to their active and alternate pools. The system brings the collection back in sync after synchronous replication is
resumed for all volumes.
Resume Synchronous Replication (SyncRep)
To resume synchronous replication (SyncRep) after it has been paused:
1.
Click
Volumes
.
2.
Expand
Volumes
and then select the volume.
3.
In the Activities panel, click
Resume SyncRep
.
After synchronous replication has been resumed:
•
The group copies to the SyncAlternate volume any changes that were made while synchronous replication was paused.
•
The volume’s SyncRep status in the General Volume Information panel indicates that the volume is out of sync until all
outstanding writes have been committed to the SyncAlternate volume. When all writes have been committed, the status
changes to in sync.
Enable Synchronous Replication (SyncRep) for a Volume Collection
To enable synchronous replication (SyncRep) for a volume collection, all volumes in the collection must:
•
Have synchronous replication enabled
•
Be in sync
•
Use the same two storage pools
•
Not belong to another SyncRep collection
•
Not be moving from one pool to another
To enable SyncRep for a volume collection:
1.
Click
Volumes
.
2.
Expand
Volume Collections
and then select the collection from the list.
3.
In the Activities panel, click
Enable SyncRep for collection
.
Disable Synchronous Replication (SyncRep) for a Volume Collection
