The show volume performanceStats command returns information about volume performance.

Supported Arrays

This command applies to any individual storage array, including the E2700, E5600, E2800, E5700, EF600 and EF300 arrays, as long as all SMcli packages are installed.

Roles

To execute this command on an E2800, E5700, EF600, or EF300 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 ["volumeName"]
volumes ["volumeName1" ... "volumeNameN"]) performanceStats

Parameters

Parameter Description

Parameter	Description
`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:
