`svolume performanceStats`命令可返回有关卷性能的信息。

支持的阵列

此命令适用于任何单个存储阵列、包括E4000、E2700、E5600、E2800、E5700、EF600和EF300阵列、前提是已安装所有SMClu软件包。

角色

要在E4000、E2800、E5700、EF600或EF300存储阵列上执行此命令、您必须具有存储管理员或存储监控角色。

环境

对于存储阵列中的每个卷、此命令将返回以下信息：

  • 存储阵列

  • IOS/s总数

  • 读取%

  • 主读取缓存命中%

  • 主写入缓存命中%

  • SSD缓存命中率

  • 当前MBs

  • 最大MBs/s

  • 当前IOS/s

  • 最大IOS/s

  • 最小IOS/s

  • 平均IOS/s

  • 最小MBs/s

  • 平均MBs /秒

  • 当前IO延迟

  • 最大IO延迟

  • 最小IO延迟

  • 平均IO延迟

语法

show (allVolumes | volume ["volumeName"]
volumes ["volumeName1" ... "volumeNameN"]) performanceStats

Parameters

参数 Description

所有卷

用于返回有关存储阵列中所有卷的性能统计信息的参数。

卷

要检索其信息的卷的名称。将卷名称括在方括号([])中。如果卷名称包含特殊字符或数字、则必须将名称用双引号("")括在方括号内。

卷

要检索其信息的多个卷的名称。使用以下规则输入卷的名称：

  • 请将所有名称用方括号([])括起来。

  • 使用空格分隔每个名称。

如果卷名称包含特殊字符或数字、请使用以下规则输入名称：

  • 请将所有名称用方括号([])括起来。

  • 请将每个名称用双引号("")括起来。

  • 使用空格分隔每个名称。

注释：

在运行`show volume performanceStat`命令之前、请运行`set session performanceMonitorInterval`命令和`set session performanceMonitorIterations`命令以定义收集统计信息的频率。

`svolume performanceStat`命令返回卷性能统计信息、如以下示例所示：
