Host Initiators not logged in to NetApp cluster using some of the paths

Last Updated:

Applies to

  • ONTAP 9
  • FCP
  • SAN
  • VMware ESXi 


  • Host initiators are zoned, but not logged into NetApp resulting in path mismatch on host end.
  • The lifs and physical ports are up and online on NetApp end, the same can be verified using fcp adapter show and net int show command.
  • SFP tx and rx power are in optimal range on storage end.
  • Some of the ESXi host initiators are not logged in to all the target LIF. fcp initiator.xml log shows the host not logged in using the lifs of all the nodes of the cluster.
  • There are other unaffected hosts logged in to the same NetApp ports using the same lifs.
  •  Every time there is a host reboot, we are seeing some or the other paths as missing. This tells me that post reboot the host is unable to initiate the session back to storage.
  • vserver fcp ping-igroup show shows zone-info-not-available for some of the paths.

fcp ping-igroup show -vserver abc -igroup xyz -check-fabric true

  • On switch end , both host and storage ports are logged in as FC4 type under nsshow log output.

  • Ensure the correct ONTAP cli context to prevent false possitive output fcp ping-initiator.


  • Below steps need to be implemeted to siolate the issue further:
  • Rescan storage adapters ( # esxcli storage core adapter rescan -A vmhbaX )
  • Toggle the switch port connected to host initiator and verify, This can be done using portdisable command on Brocade switch and shutdown command on Cisco switch.
  • Reset the Host HBA on VMware (# esxcli storage san fc reset -A vmhbaX )
  •  Reset the LIFs on NetApp end using below command:
NOTE : If the storage LIFs are zoned with any other hosts, ensure those hosts have proper redundant paths and multipathing configured. 

::> net int modify -vserver <vserver_name> -lif <lif_name> -status-admin down
::> net int modify -vserver <vserver_name> -lif <lif_name> -status-admin up
