The show volume performanceStats command returns information about volume performance.

Supported Arrays​

This command applies to an individual DE2000H, DE4000H, DE4000F, DE6000H, or DE6000F storage array.

Roles​

To execute this command on an storage array, you must have the Storage Admin or Storage Monitor role.

Context​

For each volume in the storage array, this command returns the following information:

  • Storage Arrays

  • Total IOs/s

  • Read %

  • Primary Read Cache Hit %

  • Primary Write Cache Hit %

  • SSD Cache Hit %

  • Current MBs/s

  • Maximum MBs/s

  • Current IOs/s

  • Maximum IOs/s

  • Minimum IOs/s

  • Average IOs/s

  • Minimum MBs/s

  • Average MBs/s

  • Current IO Latency

  • Maximum IO Latency

  • Minimum IO Latency

  • Average IO Latency

Syntax​

show (allVolumes | volume ["<var id="GUID-1A331840-A3E0-481F-B1D3-516D777E0B0D__V1111763" className="keyword varname">volumeName</var>"] 
volumes ["<var id="GUID-1A331840-A3E0-481F-B1D3-516D777E0B0D__V1111764" className="keyword varname">volumeName1</var>" ... "<var id="GUID-1A331840-A3E0-481F-B1D3-516D777E0B0D__V1111765" className="keyword varname">volumeNameN</var>"]) performanceStats

Parameters​

ParameterDescription
allVolumes The parameter to return performance statistics about all of the volumes in the storage array.
volume

The name of a volume for which you want to retrieve information. Enclose the volume name in square brackets ([ ]). If the volume name has special characters or numbers, you must enclose the name in double quotation marks (" ") inside square brackets.

volumes

The names of several volumes for which you want to retrieve information. Enter the names of the volumes using these rules:

  • Enclose all of the names in square brackets ([ ]).

  • Separate each of the names with a space.

If the volume names have special characters or numbers, enter the names using these rules:

  • Enclose all of the names in square brackets ([ ]).

  • Enclose each of the names in double quotation marks (" ").

  • Separate each of the names with a space.

Notes​

Before you run the show volume performanceStat command, run the set session performanceMonitorInterval command and the set session performanceMonitorIterations command to define how often you collect the statistics.

The show volume performanceStat command returns volume performance statistics as shown in this example:
