lsvdiskanalysis

Use the lsvdiskanalysis command to display information for thin provisioning and compression estimation analysis-report for a single volume or multiple volumes.

Syntax

Parameters

-delim delimiter: (Optional) Specify a delimiter to separate data in the output.
-nohdr: (Optional) Suppress the headings in the output.
-filtervalue attribute=value: (Optional) Specifies a list of one or more filters. Only objects with a value that matches the filter attribute value are displayed.
-filtervalue?: (Optional) Displays a list of valid filter attributes.

vdisk_id | vdisk_name: Specifies the volume (by ID or name) to display compression estimation status for.

Description

This command displays information for thin provisioning and compression estimation analysis-report for a single volume or multiple volumes.

This table provides the attribute values that can be displayed as output view data.

Table 1. Output from the lsvdiskanalysis command
Attribute	Description
id	Indicates the ID (by number) of the object.
state	Indicates one of the following values: `idle` Indicates that the volume was never analyzed. `scheduled` Indicates that the volume is scheduled for analysis (the analysis starts based on ascending volume IDs). `active` Indicates that the volume is being analyzed. `estimated` Indicates that the volume was analyzed and the analysis results reflect the estimated savings from thin provisioning and compression. `sparse` Indicates that the volume was analyzed but not enough samples of nonzero data were found. `cancelling` Indicates that the analysis is ongoing and a request exists to cancel the analysis, but the analysis is not yet ended. `automatic` Indicates that the volume is being analyzed due to automatic scheduling.
started_time	Indicates the date and time that the analysis started, which helps determine how long an estimate takes. The value must be an alphanumeric data string or be empty if analysis never started.
analysis_time	Indicates the date and time that the analysis ends to help determine how current the results are. If you cancel the analysis, the value for the time is invalid (`0`, and it is not displayed). While active, time is invalid as well and does not reflect expected completion time. The value must be an alphanumeric data string or be empty if analysis never occurred.
capacity	Indicates the provisioned capacity (host size) of the volume.
thin_size	Indicates the estimated size of the data without zero portions (thin-provisioned size).
thin_savings	Indicates how much data saving is expected if it is a thin-provisioned volume.
thin_savings_ratio	Indicates the percent of data that is saved by thin-provisioned. The number must be a percentage.
compressed_size	Indicates the estimated size of any nonzero data after compression completes.
compression_savings	Indicates how much data to expect to save if the volume is a compressed volume.
compression_savings_ratio	Indicates the amount of data that is saved by compression. The number must be a percentage.
total_savings	Indicates how much data to expect to save by converting a volume to a compressed volume.
total_savings_ratio	Indicates the amount of data that is saved by compression is based on the overall volume capacity, which includes the thin nature of compressed volumes. The number must be a percentage.
margin_of_error	Indicates the accuracy estimation. The number is a percentage.
file_system	Indicates the file system(s) of the volume
