Viewing sync mirror groups
You can view all sync mirror groups in the sync mirror groups list.
To display the sync mirror groups list:
In the navigation tree, click the Sync Mirror Groups node. The sync mirror groups list appears in the

Original Virtual Disk
Name
The status of the sync mirror group. Possible values:
• Normal—The group’s tasks are proceeding normally.
• Journal—One of the tasks is failing, but other tasks are continuing because the
group is configured in Continue-on-Fail mode.
• Failed—The group is paused because at least one of the tasks is failing and
the group is configured in Always Synchronized mode.
• Partial—A host error occurred and the mirror service cannot determine from
which virtual disk to recover.
• SnapSync—The group is in the process of copying data from one task to an-
other in the background. This process is done to initiate a new task or when
a task is recovered after a failure. When the group’s status is SnapSync, you
cannot create another task.
• Absent—The host that has permission to the sync mirror group is failed or ab-
sent. All tasks are in unknown states.
For information about what action you can take when the group’s status indicates
a problem, see “Troubleshooting” on page 298, or if the task belongs to a group
that is a cluster resource, see “Mirroring cluster virtual disks” on page 297.
Status
The mode of operation. Possible values:
• Continue-on-Fail—In this mode, if one of the tasks in the group fails, the other
tasks continue. The host remains online because the read and write I/Os are
serviced by the tasks that are normal. This mode is the default mode.
• Always Synchronized—In this mode, all the mirrored virtual disks are always
synchronized. If one of the tasks fails, the mirroring is paused until the problem
is resolved. In this event, all host I/Os are paused from reaching any of the
virtual disks, including the source virtual disk, until the problem is resolved.
