We are currently setting up an iSCSI SVM on the DG5000 QLC Storage and encountered a problem in System Manager. It states that controller node2 has no logged-in initiators.
However, upon checking the servers (ESXi) and the storage cluster, we noticed that the active iSCSI sessions are indeed present on both controller nodes.
Additionally, we performed an ONTAP upgrade from v9.15.1P2 to v9.16.0, but this did not resolve the issue. We observed that the virtual machine running on the Lenovo Storage Datastore continued to operate smoothly even after we shut down the iSCSI interfaces on Controller Node1.
Further testing showed that keeping only one port active from each controller for all ports that are part of the iSCSI port set yielded good results, confirming that multipath functionality is intact.
Not sure, how to fix the errors seen in the GUI. Attaching the screenshots
