Detaching synchronous mirror tasks
Detaching a task deletes the task and its auxiliary virtual disks. You can detach tasks only in the
following situations:
• If a group’s status is Normal and no process of synchronizing dirty regions is currently running,
you can detach any task in the group.
• If a group's status is Failed.
• If a group’s status is Journal, you can detach a failed task.
To detach a task:
1. Click the Sync Mirror Task tab.
2. Right-click a task.
3. Select Detach. A confirmation screen appears.
4. Click Finish. The task is detached.
Using snapshots with synchronous mirrors
You can create a snapshot PiT on a synchronous mirror group or on the destination virtual disk of a
synchronous mirror task. When you create a PiT on a group, a PiT is created on the virtual disk of
each task. When you create a snapshot PiT on a virtual disk, the PiT is created only on that virtual
disk.
To create a PiT:
1. Select the entity on which to create the PiT.
• To create a PiT on the destination virtual disk, right-click the virtual disk, rather than the task,
on which to create a user PiT. The Create User PiT screen appears.
• To create a PiT on the group, select Manage> Create User PiT. The Create User PiT screen
appears.
2. In the PiT name field, enter a name for the PiT. This is the PiT name only on the source domain
of the group. When a user PiT is copied to task destinations, the mirror service automatically
generates a new name for the PiT. The new name is a combination of the destination virtual disk
name, the letters “UP” to indicate a user PiT, and a unique time stamp number assigned to the
PiT when it was created by the source domain.
