状态信息

适用于

 

  • 平台: FAS2220 , FAS2240-2 , FAS2240-4 , FAS2520 , FAS2552 , FAS2554 , FAS2620 , FAS2650 , FAS2720 , FAS2750 , AFF-A200 和 AFF-A220
  • 高可用性配置(机箱中插入了 2 个处理器控制模块( PCM )并配置为进行 HA 操作)
  • 仅限内部存储(未连接外部 SAS 存储架)
  • PCMS 上的 0A 或 0B SAS 端口直接连接到其他 PCM 上的 SAS 端口

问题

如果发现以下任何症状,则本文适用。
  1. EMS 事件:当 PCM A 上的端口 0B 直接连接到 PCM B 上的端口 0B 时,您偶尔会在事件日志中看到此 EMS 事件: config.invalid.porttoport
示例:
 Fri Dec 09 14:30:00 PST [node1: pmcsas_intrd_0: config.invalid.PortToPort:error]: SAS adapter "0b" is attached to another SAS adapter. 
  1. 环境:其中一个节点运行环境机架 Nodeshell 命令。内部架 [2] 和 [4] SAS 扩展器端口上列出的 SAS 电缆序列号相同。扩展器端口 [2] PCM A 上的 0 A 端口、端口 [4] PCM B 上的 0 A 端口 
 SAS cable information by element: [1] Internal connector [2] Vendor: Amphenol Type: QSFP passive copper 0.5-1.0m ID: 01 Swaps: 0 Serial number: APF14131767EE1 Part number: 112-00176+A0 [3] Internal connector [4] Vendor: Amphenol Type: QSFP passive copper 0.5-1.0m ID: 00 Swaps: 0 Serial number: APF14131767EE1 Part number: 112-00176+A0 
  1. sysconfig -a :个节点运行 sysconfig -a nodeshell 命令。以下情况得到了观察:
  • 系统存储配置:单路径 HA
  • 两个节点上的 SAS 0B 端口显示相同的 QSFP 序列号。
