Troubleshooting
The following tables suggest possible actions you can take when the status of a task or group indicates
a problem.
Table 121 Possible actions according to task status
Possible actionDescriptionTask status
None required.
The status of the task’s destination
virtual disk is normal and the task
is synchronized with the other tasks
in the group.
Normal
None required.
The task is in the process of syn-
chronizing with the other tasks in
the group.
Snapsync
Check the host that is running the Local Mirror Group.
Find out if indeed the task's destination virtual disk is
partial. Check the host’s connectivity with the storage
system as well as fabric zoning and LUN masking
configuration. Try to return the virtual disk’s status to
normal. Try to resume the group (see “Resuming syn-
chronous mirror groups” on page 294).
The mirror service cannot write to
the destination virtual disk of the
task, probably because the virtual
disk cannot be accessed (virtual
disk in Partial status).
Failed
Check VSM connectivity with the fabric, VSM servers,
storage system, as well as fabric zoning and LUN
masking. Try to return the task’s virtual disks to normal
status. Try to resume the group (see “Resuming syn-
chronous mirror groups” on page 294).
The status of the group to which the
task belongs is Partial or Failed or
the host that has permission to ac-
cess the group is Absent or Failed.
Unknown
Table 122 Possible actions according to group status
Possible actionDescriptionTask status
None required.
The group’s tasks are proceeding
normally.
Normal
Try to fix any failed tasks. Once fixed, try to resync
the group (see “Resynchronizing synchronous mirror
groups” on page 294).
If you cannot fix the failed tasks, you can detach the
failed tasks. This returns the group status to normal
(see “Detaching synchronous mirror
tasks” on page 296).
One of the tasks is failing, but the
group remains functional because
it is running in Continue-on-Fail
mode and has tasks whose statuses
are normal.
