Last Updated:

Applies to

  • ONTAP 9
  • SAN
  • iSCSI
  • Multipath with 2 systems in HA configuration


When performing an upgrade, the HA partner (node-01) rebooted to upgrade. With reboot

  • Port for iSCSI logical interface (LIF) did not come back online
  • This results in offline of iSCSI LIFs on the partner system (node-01)
  • Upgrade continues with takeover of the system (node-02), resulting in no more paths for servers to connect to the LUN
