Verify the SAN configuration after an upgrade

After an ONTAP upgrade, in a SAN environment, you should verify that each initiator that was connected to a LIF before the upgrade has successfully reconnected to the LIF.

  1. Verify that each initiator is connected to the correct LIF.

    You should compare the list of initiators to the list you made during the upgrade preparation. If you are running ONTAP 9.11.1 or later, use System Manager to view the connection status as it gives a much clearer display than CLI.

    System Manager

    1. In System Manager, click Hosts > SAN Initiator Groups.

      The page displays a list of initiator groups (igroups). If the list is large, you can view additional pages of the list by clicking the page numbers at the lower right corner of the page.

      The columns display various information about the igroups. Beginning with 9.11.1, the connection status of the igroup is also displayed. Hover over status alerts to view details.

    CLI

    • List iSCSI initiators:

      iscsi initiator show -fields igroup,initiator-name,tpgroup

    • List FC initiators:

      fcp initiator show -fields igroup,wwpn,lif
