适用于

  • ONTAP 9
  • FCP
  • 专用集成电路(ASIC)

问题

  • 在维护(接管/回馈)期间 使用相同 HBA 专用集成电路(ASIC)的两个端口不会启动。
  • Sysconfig -a可能会报告使用相同 ASIC 的两个端口为  Operational Status: startup
  • 主机使用相同 ASIC 上的 FC 目标端口检测到故障路径或无法访问 LUN。
  • 同一 HBA/ASIC 上的两个 FC 目标端口在过去同时启动和关闭时不可靠。
    • 示例:2a 自动重置,2b 报告为脱机,故障排除后可能会在短时间内恢复联机。
  • STIO 和适配器错误可以在系统日志 (EMS) 中看到。
  • 重置交换机端口不会改变 ONTAP 目标端口状态,并且status-adminup.
  • 交换机, ONTAP SFP 和 FC 电缆已检查并更换。
示例:
Cluster::> network interface show -data-protocol fcp -fields status-admin,status-oper,status-extended
vserver          lif                   status-oper status-extended      status-admin
---------------- --------------------- ----------- -------------------- ------------
svm1              Node_1_4c             down        LIF not initialized  up
svm1              Node_1_4d             down        LIF not initialized  up
Cluster::>network fcp adapter show
Node  Adapter  Est  Address Admin Status  Status
---- --------  ---- -------  --------     -------
abc    2b      false   0       up         offline
 
  • EMS log 显示:
ERROR callhome.fcp.sram.dump: Call home for FCP SRAM DUMP.
ERROR scsitarget.fct.port.offline: Fibre Channel Target port 2b was taken operationally offline due to too many errors received by the FCT driver.
ALERT scsitarget.hwpfct.initFailed: Initialization of adapter failed on Fibre Channel target adapter 2b.
NOTICE scsitarget.hwpfct.errorReset: An error was encountered in the FC target driver on Fibre Channel target adapter 2a. The adapter will be automatically reset to clear the
