Display aggregate storage efficiency details

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

Description

The storage aggregate show-efficiency command displays information about the 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.

| [-advanced ] (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.

[-aggregate <aggregate name>] - Name of the Aggregate

Displays the aggregate name. If this parameter is specified, the command displays detailed information about the storage efficiency of the specified aggregate.

[-node {<nodename>|local}] - Node where Aggregate Resides

Displays the node which owns the aggregate. If this parameter is specified, the command displays storage efficiency information only about the aggregates that are located on the specified node.

[-volume-logical-used {<integer>[KB|MB|GB|TB|PB]}] - Logical Space Used for All Volumes

Displays the logical size used by all the volumes in the aggregate.

[-volume-physical-used {<integer>[KB|MB|GB|TB|PB]}] - Physical Space Used for All Volumes

Displays the physical size used by all volumes in the aggregate.

[-volume-efficiency-saved {<integer>[KB|MB|GB|TB|PB]}] - Space Saved by Volume Deduplication (privilege: advanced)

Displays the total disk space that is saved by deduplication and FlexClone for files, LUNs or NVMe namespaces by all volumes in the aggregate.

[-volume-dedupe-zero-pattern-saved {<integer>[KB|MB|GB|TB|PB]}] - Space Saved by Volume Deduplication and pattern detection (privilege: advanced)

Displays the total disk space that is saved by deduplication, Zero pattern detection and FlexClone for files, LUNs or NVMe namespaces by all volumes in the aggregate.
