  1. We run in the follwing situation with Trident 24.06.1 when our DataCenter Partner was updating NetApp MetroCluster to version 9.12.1:
    The problem corresponds to https://kb.netapp.com/Cloud/Astra/Trident/Trident_iSCSI_paths_do_not_recover_after_ONTAP_Upgrade
  2. We ReScan and Reboot all Cluster Nodes as discribed in the KB Article.
  3. Nevertheless, we now have some cluster nodes in the following state:
    Trident-Main Container on Trident Node Pod Log:
    "Time="2025-03-10T15:51:28Z" level=error msg="GRPC error: rpc error: code = Internal desc = scan not completed for LUN 3 on target iqn.1992-08.com.netapp:sn.4820a5e5016b11eba09a00a0989f9c88:vs.75" logLayer=csi_frontend requestID=dc392fb7-fee7-4add-973f-48b05fa68455 requestSource=CSI"

--> Pods with PVCs RWO/SAN cannot be terminated.

Any Ideas what we can do?

Hello Scott, thanks for your answer.
As already written, the rescan is a recommendation from Netapp in the linked KB article. We have already done this several times (as well as the drain&reboot). Unfortunately, the status did not change....
