Possible action Description Task status
Try to fix any failed tasks. Once fixed, try to resume
the group (see “
Detaching synchronous mirror
tasks ” on page 296).
If all tasks are not fixed, do either of the following:
• Change the group mode to Continue-on-Fail (see
“
Changing the synchronous local mirror group
mode ” on page 294). The group status changes to
Journal. The group is available and uses the tasks
that are normal. Follow the recovery procedure for
groups with status Journal.
• Detach the failed tasks to return the group’s status
to Normal (see “
Detaching synchronous mirror
tasks ” on page 296).
The group is paused because at
least one of the tasks is failing, and
the group is running in Always
Synchronized mode.
Failed
On the host running the sync mirror group, verify that
the status of each task’s destination virtual disk is
Normal. If the status of a destination virtual disk is
Partial instead of Normal, do the following:
• Check VSM connectivity with the storage systems
and the zoning and LUN masking configuration.
• After all tasks are fixed, resume the group (see
“
Resuming synchronous mirror
groups ” on page 294).
• If the problem persists, delete the group (see “ De-
leting synchronous mirror groups ” on page 295).
Deleting a group when the status is Partial detaches
all the tasks and leaves the virtual disks without
host permissions. You can then use the remaining
virtual disks.
A host error occurred and the mir-
ror service cannot determine from
which virtual disk to recover.
Partial
Wait until the group’s status returns to normal before
you add another task.
The group is in the process of
copying data from one task to an-
other in the background. This pro-
cess is initiated when a new task is
created or when the mirror recovers
a task after it failed.

Troubleshooting cluster virtual disks
This section describes each task status and group status for sync mirror groups used by cluster nodes,
and suggests possible actions you can take when the status indicates a problem.
For a description of each task status and the possible actions to take, see Table 121 on page 298.
Table 123 Possible actions according to group status for cluster virtual disks
Possible action Description Task status
None required.
The group’s tasks are proceeding
normally. At least one cluster node
is present.
