  • ONTAP 9
  • Automated Nondisruptive Upgrade (ANDU) 
  • Batch Method

Issue

  • During an ANDU ONTAP upgrade a data LIF (Logical interface) migration fails causing the upgrade process to pause.
  • When a node takes over its partner, the partner's LIFs migrate according to network interface failover target rules.
  • In this scenario, since the partner was not part of the data LIF failover target, it tried to fail over to another node in the cluster.
    • The LIF migration fails since the target node was not available as it was going through the upgrade process.

Example:

::> net int show -vserver test -lif lif4 -fields failover-group
  (network interface show)
vserver  lif  failover-group
-------- ---- --------------
test     lif4  TEST 

::> network interface failover-groups show -failover-group TEST
                                  Failover
Vserver          Group            Targets
---------------- ---------------- --------------------------------------------
<admin vserver>
                 TEST
                                  node-04:a0a-105, node-01:a0a-105

::> cluster image show-update-progress
