Display cumulated storage efficiency details

Availability: This command is available to cluster administrators at the admin privilege level.

Description

The storage aggregate show-cumulated-efficiency command displays information about the cumulated storage efficiency of all the aggregates. The storage efficiency is displayed at four different levels:

  • Total

  • Aggregate

  • Volume

  • Snapshot and FlexClone volume

Parameters

{ [-fields <fieldname>,…​]

If you specify the -fields <fieldname>, …​ parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.

| [-details ]

Use this parameter to show additional Storage Efficiency Ratios.

| [-all-details ] (privilege: advanced)

Use this parameter to show additional Storage Efficiency Ratios and size values.

| [-instance ] }

If you specify the -instance parameter, the command displays detailed information about all fields.

[-aggregates <aggregate name>,…​] - List of Aggregates to cumulate Storage Efficiency ratio

If this parameter is specified, the command calculates the cumulated storage efficiency of the specified list of aggregates.

[-nodes {<nodename>|local}] - List of Aggregates to cumulate Storage Efficiency ratio

If this parameter is specified, the command calculates the cumulated storage efficiency of aggregates that are located on the specified list of node.
