[NODE-02: fct_tpd_thread_0: fcp.io.status:debug]: STIO Adapter 5a resetting with 0 ITN and 0 commands to drain.
[NODE-02: nvmf_master_0: nvmf.spdk.err:debug]: fc_adm_api.c:1448 Hw port 0 already offline. err = 2
[NODE-02: fct_tpd_thread_0: scsitarget.hwpfct.initFailed:alert]: Initialization of adapter failed on Fibre Channel target adapter 5a.

Follow the below steps to narrow down the issue

  • Identify initiator by using the S_ID (source ID)to correlate with respective entries in switch log or EMS log (via event log show or ActiveIQ AutoSupports)
  • Find the respective initiator login or switch log entry: [NODE-02: fct_tpd_work_thread_0: scsitarget.fct.portLogin:notice]: Login at target FC port: '5a' by initiator port: 'WWPN​​​​​' address 0xS_ID. The target virtual port is: 'NetApp FC Target Port (LPe32000) svm-NAME:NODE-02_fc_lif_1'.​​​
  • Verify all physical components of the connection end to end are are healthy, Identify reason and remedy factor causing aborts/resets resulting in fcp.io.status:debug messages.
