Suspending a replication
You can suspend replication operations for a specified replication set from its primary system. You can suspend replications from
a replication set's primary system only.
When you suspend a replication set, all replications in progress are paused and no new replications are allowed to occur. You
can abort suspended replications. After you suspend replication, you must resume it to allow the replication set to resume
replications that were in progress and allow new replications to occur. For more information, see Stopping a replication or
Resuming a replication.
If replications are attempted during the suspended period (including scheduled replications), the replications will fail.
Suspend a replication
NOTE: If CHAP is enabled on one system within a peer connection, be sure that CHAP is configured properly on the
corresponding peer system before initiating this operation. For more information about configuring CHAP, see CHAP and
replication.
1. In the Replications topic, select a replication set that is currently being replicated in the Replication Sets table.
2. Select Action > Suspend Replication.
3. Click OK. The replications on the replication set are suspended and the status of the replication set changes to Suspended.
Resuming a replication
You can resume the replication operations of a specified suspended replication set. You can resume replications from a
replication set's primary system only.
When a replication set is suspended, all replications in progress are paused and no new replications are allowed to occur.
When you resume replications, all paused replications are resumed and new replications are allowed to occur. If you stopped a
replication while the replication set was suspended, the stopped replication does not resume.
Resume a replication
NOTE:
If CHAP is enabled on one system within a peer connection, be sure that CHAP is configured properly on the
corresponding peer system before initiating this operation. For more information about configuring CHAP, see CHAP and
replication.
1. In the Replications topic, select a replication set for which replications were suspended in the Replication Sets table.
2. Select Action > Resume Replication.
3. Click OK. Replications on the replication set are resumed and the status of the replication set changes to Running.
Manage replication schedules from the Replications
topic
You can modify or delete scheduled replication tasks on the primary system.
1. In the Replications topic, select a replication set on the primary system that has an associated schedule from the Replication
Sets table.
2. Select Action > Manage Schedules.
The Manage Schedules panel opens.
3. Select the schedule to modify. Its settings appear at the bottom of the panel.
4. If you want to create a replication of the last snapshot in the primary volume, select the Last Snapshot check box.
