How to setup an optimal iSCSI connection from Linux with ONTAP
Applies to
- ONTAP 9 to 9.10
- RHEL 7, RHEL 8, CoreOS, CentOS
Description
Due to the way iSCSI LIFs behave in (Clustered) ONTAP 8.2 to 9.10, where the IP address is fixated on one network interface, multipathing is required to work correctly even for iSCSI. Additionally, some changes can be made for better performance.
