Answer

  • When a MetroCluster is operating normally, all of the LIFs hosted on a MetroCluster sync-destination vserver (denoted by the suffix '-mc' on the vserver name) are configured as admin-up, but operationally-down (up/down).
Example:
A LIF in up/down status:
ClusterA::> network interface show -status-oper down
            Logical    Status     Network            Current       Current Is
Vserver     Interface  Admin/Oper Address/Mask       Node          Port    Home
----------- ---------- ---------- ------------------ ------------- ------- ----
svm1-mc
            nas_lif    up/down    1.2.3.4/24         ClusterA-01   e10a    true

 
Verifying that the vserver is a sync-destination vserver
ClusterA::> vserver show -vserver svm1-mc
                               Admin      Operational Root
Vserver     Type    Subtype    State      State       Volume     Aggregate
----------- ------- ---------- ---------- ----------- ---------- ----------
svm1-mc     data    sync-destination      stopped     svm1_root  aggr1
                               running                          
Note: The vserver is in the same state as the LIF (Admin State 'running', Operational State 'stopped')
  • This happens because the vserver and the LIFs are not brought up Operationally unless there is a metrocluster switchover operation.
  • This is normal and by design, there is no cause for concern.
  • These LIFs will also show as "Unavailable" in the system manager which is also normal when there is no switchover active.

Additional Information

  • To view the LIFs not belonging to the sync-destination SVM that are operationally-down run the command these parameters:
    ClusterA::> network interface show -status-oper down -status-extended !"This LIF is down because its Vserver is stopped"*
  • If the LIFs in this state are not associated with a sync-destination vserver:
