问题描述

事件日志中会显示以下错误消息:
 
Cluster1::> event log show -message-name scsi.cmd.abortedByHost
Time         Node    Severity    Event
------------------- ------- ------------- ---------------------------
10/4/2020 07:09:46  Node01   ERROR      Disk device brocade-fab1-sw1:13.126L1506: Command aborted by host adapter: ...
10/4/2020 05:16:42  Node01   ERROR      Disk device brocade-fab1-sw3:13.126L542: Command aborted by host adapter: ...
10/4/2020 03:18:07  Node01   ERROR      Disk device brocade-fab1-sw3:13.126L1: Command aborted by host adapter: ...
 
 
上述SCSI错误通常表示 链路/物理层问题。一旦出现链路层问题、也会 scsi.path.excessiveErrors:error 报告:
 
Cluster1::> event log show -message-name scsi.path.excessiveErrors
Time         Node   Severity  Event
------------------- ------ -------- ---------------------------
10/4/2020 05:42:46  Node01  ERROR   Excessive errors encountered by adapter 11a on disk device brocade-fab1-sw1:13.126.
10/4/2020 05:16:42  Node01  ERROR   Excessive errors encountered by adapter 11a on disk device brocade-fab1-sw3:13.126.

 
 
  • scsi.cmd.abortedByHost 报告本地和远程交换机上的所有磁盘
  • scsi.path.excessiveErrors 由单个节点上的单个端口报告

因此、需要重点关注端口与其所连接的交换机之间的链路。statsclear 启动后、在启动程序所连接的端口上报告新的CRC错误:

brocade-fab1-sw1:admin> porterrshow 

     frames   enc  crc crc   too   too   bad   enc   disc   link
