Issue

When an ONTAP storage node is upgraded, that node is taken over by its HA partner and when the ONTAP partner HA node does a failover giveback, some iSCSI storage paths do not recover due to issues on the Kubernetes host side.
 
After the giveback of the ONTAP node, only half of the expected iSCSI paths are seen for some of the LUN's from some of the Kubernetes nodes and Trident logs will show something similar to the below errors:
