iSCSI LUN outage during ONTAP Upgrade
Applies to
- ONTAP 9
- SAN
- iSCSI
- Multipath with 2 systems in HA configuration
Issue
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
