lsvdiskanalysis

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

Syntax

lsvdiskanalysis [ -nohdr ] [ -delim delimiter ] [ -filtervalue attribute=value ] [ -filtervalue? ] [ { [ vdisk_id ] | [ vdisk_name ] } ]

Parameters

-nohdr

(Optional) By default, headings are displayed for each column of data in a concise style view, and for each item of data in a detailed style view. The -nohdr parameter suppresses the display of these headings.

Note: If there is no data to be displayed, headings are not displayed.

-delim delimiter

(Optional) By default in a concise view, all columns of data are space-separated. The width of each column is set to the maximum width of each item of data. In a detailed view, each item of data has its own row, and if the headers are displayed, the data is separated from the header by a space. The -delim parameter overrides this behavior. Valid input for the -delim parameter is a 1-byte character. If you enter -delim : on the command line, the colon character (:) separates all items of data in a concise view; for example, the spacing of columns does not occur. In a detailed view, the data is separated from its header by the specified delimiter.

-filtervalueattribute=value

(Optional) Specifies a list of one or more filters. Only objects with a value that matches the filter attribute value are displayed.

Note: Some filters allow the use of a wildcard when you enter the command. The following rules apply to the use of wildcards with the Lenovo Storage V series system CLI:

The wildcard character is the asterisk (*).
The command can contain a maximum of one wildcard.
When you use a wildcard, enclose the filter entry within double quotation marks (""), as follows:
```
lsvdiskanalysis -filtervalue "usergrp_name=md*"
```

-filtervalue?

(Optional) Displays the valid filter attributes for the -filtervalueattribute=value parameter:

id
name
state

vdisk_id | vdisk_name

(Optional) 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.

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

Table 1. lsvdiskanalysis output
Attribute	Description
id	Indicates the ID (by number) of the object.
analysis_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 the analysis is undergoing but there is a request to cancel it, and the analysis did not end.
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 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 virtual 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 is expected to be saved 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 based on the overall volume capacity, which includes the thin nature of compressed volumes. The number must be a percentage.
accuracy	Indicates the accuracy estimation. The number must be a percentage.
