  • STIO 挂起 cmd 事件与 state=10 和 state =5 在 EMS 中报告了相同的 SID 0x61xx0 

     Sun May 14 23:13:42 +0530 [NetApp: fct_tpd_thread_1: fcp.io.status:debug]: STIO Adapter:2b, found hung cmd:0xfffff8188234ab78(state=10, flags=0x2, ctio_sent=2/3,RecvExAddr=0x2ae5, OX_ID=0x1e66, RX_ID=0xffff,SID=0x61xx0, Cmd[28], req_q_free:0)

Wed Dec 20 21:36:21 +0000 [NetApp: fct_tpd_thread_3: fcp.io.status:debug]: STIO Adapter:4d, found hung cmd:0xfffff81e0a7d1038(state=5, flags=0x0, ctio_sent=1/5,RecvExAddr=0x271f, OX_ID=0x5ee9, RX_ID=0xffff,SID=0x61xx0, Cmd[2A], req_q_free:0)

  • 注意：state=5: DATAOUT_WAIT 这表示 FC 目标在接受写入请求后正在等待主机返回某些内容；但是，在预期的超时值内没有返回任何内容。
