《allVolumes》 |
傳回儲存陣列中所有磁碟區效能統計資料的參數。 |
《Volume》(Volume) |
要擷取資訊的Volume名稱。將磁碟區名稱括在方括弧([])內。如果Volume名稱含有特殊字元或數字、則必須在方括弧內以雙引號("")括住名稱。 |
《Volume》(Volume) |
您要擷取資訊的多個磁碟區名稱。使用下列規則輸入磁碟區名稱:
如果磁碟區名稱有特殊字元或數字、請使用下列規則輸入名稱:

附註
在您執行「show volume performanceStat」命令之前、請先執行「show session performanceMonitorInterval'命令和「show session performanceMonitor迭 代」命令、以定義收集統計資料的頻率。
「show volume performanceStat」命令會傳回Volume效能統計資料、如下列範例所示:
