      Drive type                   = SAS

Operation failed. Error code: 0x67001a7

Cause

有時，問題出在管理方面，重新啟動 Unity 管理服務可解決此問題。 

但是，這也可能是真正的錯誤，可能是因為設置或驅動器不相容。 

    Resolution

    如需如何重新啟動 Unity 管理服務的指南，請參閱 Dell 知識文章：


    service@(none) spa:~> uemcli /stor/config/dg show

          ID                           = dg_2
          Drive type                   = SAS Flash 2
          FAST Cache                   = yes   <<<<<<<<<<<<<<<<<<<<<<<<
          Drive size                   = 196971960832 (183.4G)
          Vendor size                  = 200.0G
          Rotational speed             = 0 rpm
          Number of drives             = 3
          Unconfigured drives          = 3
          Capacity                     = 590915882496 (550.3G)
          Recommended number of spares = 1
