问题解答

FC队列深度 是按端口 而不是按主机总线适配器(HBA)确定的、因此此问题不会解析SCSI队列访问的底层端口问题描述。 

示例:

每个HBA端口的队列深度可能为1945 ( 对于关键SCSI命令为2048-5%)将FC链路移动到另一个HBA端口不会更改此设置。

或者:

  • 考虑调整环境和主机 计算队列深度概述
  • 请考虑添加其他目标端口和FC链路 
    • 示例:从 每个节点2个目标端口转到4个、这样可以减轻每个端口上的队列深度压力。
  • 建议将环境移至支持更多队列深度的HBA卡、例如4096 (对于关键SCSI命令、为-5 %)。

检查每个端口的队列深度:
