Suspending asynchronous mirror groups
When you suspend an async mirror group, all tasks are suspended and standard mirror PiT creation
stops. While a group is suspended, you can still create a user PiT.
To suspend an async mirror group:
1. Right-click a group.
2. Select Manage > Suspend. A confirmation screen appears.
3. Click Finish. The group is suspended.
To suspend all async mirror groups:
1. Right-click the Async Mirror Groups node.
2. Select Suspend all Async Mirror Groups. A confirmation screen appears.
3. Click Finish. All async mirror groups with source elements on the local domain are suspended.
Resuming async mirror groups
When you resume an async mirror group that was suspended, standard PiT creation is resumed and
all tasks are resumed.
To resume a suspended async mirror group:
1. Right-click the group.
2. Select Manage > Resume. A confirmation screen appears.
3. Click Finish.
To resume all suspended async mirror groups:
1. Right-click the Async Mirror Groups node.
2. Select Resume all Async Mirror Groups. A confirmation screen appears.
3. Click Finish. All async mirror groups are resumed.
Detaching async mirror groups
Detaching an async mirror group deletes the group but maintains the source element and all destination
virtual disks and the PiTs on the source and on the destinations. Detaching is enabled regardless of
the status of the group’s tasks and is useful in the event of damage to your source virtual disk, in which
case you can detach the group in order to use a destination virtual disk for recovery.
To detach an async mirror group:
1. Select the group.
2. Right-click Manage > Detach. A confirmation screen appears.
3. Click Finish. The group is detached.
Splitting async mirror groups
Splitting an async mirror group deletes the group but does not delete the source and destination virtual
disks or their PiTs. You can only split a group if certain conditions apply. These conditions ensure that
the split results in identical virtual disks on the source and on the destinations. Splitting therefore
