Issue

 

  • Path redundancy lost for multiple host types
  • Negative performance impact
  • Receive errors in EMS/Event log
  • Admin down/up ports can temporarily get paths back
  • Shutdown specific ports can resolve issues
Example:
fct_tpd_work_thread_0: fcp.io.status:debug]: STIO Adapter:0c AEN 0x8048 (RECV_ERROR) MboxStatus1 0xfffe MboxStatus2 0x1
fct_tpd_work_thread_0: fcp.io.status:debug]: STIO Adapter:0c AEN 0x8048 (RECV_ERROR) MboxStatus1 0x1008 MboxStatus2 0xc1
fct_tpd_work_thread_0: fcp.io.status:debug]: STIO Adapter:0c AEN 0x8048 (RECV_ERROR) MboxStatus1 0xfffe MboxStatus2 0x1
