The volume snapshot show command displays information about Snapshot copies. The command output depends on the parameters specified with the command. If no parameters are specified, the command displays a table with the following information about all the available Snapshot copies:

Vserver name
Volume name
Snapshot copy name
State
Size
Percentage of total blocks in the parent volume
Percentage of used blocks in the parent volume

To display a detailed list view with additional information, run the command and select the -instance view. In addition to the above mentioned information about the Snapshot copies, the detailed list view provides the following additional information:

Creation time
Snapshot busy
List of the Snapshot copy’s owners
Comment associated with the Snapshot copy
SnapMirror Label associated with the Snapshot copy
7-Mode Snapshot
Constituent Snapshot
Expiry Time
SnapLock Expiry Time

At the advanced or higher privilege level the detailed view provides the following additional information:

Snapshot copy’s Dataset ID
Snapshot copy’s master Dataset ID
Number of consistency points in the Snapshot copy
Internal status of the Snapshot copy
File system version
File system block format
Physical Snap ID
Logical Snap ID
Database record owner
Snapshot tags
Instance UUID
Version UUID
Node
AFS used size
Compression savings size
Deduplication savings size
Vbn0 savings size
Reserved size
Logical used size
Performance metadata size
Status of FlexGroup Qtree support in the Snapshot copy

For Snapshot copies whose parent volume is a FlexGroup, some information is not available and empty values will be displayed. This information includes:

State
Size
Percentage of total blocks in the parent volume

Percentage of used blocks in the parent volume

All information is available for Snapshot copies whose parent volume is a FlexGroup Constituent.

At the admin and advanced privilege level, Snapshot copies whose parent volume is a FlexGroup Constituent are not displayed by default. To display these, run the commmand and set the is-constituent to true . At the diagnostic or higher privilege level, all Snapshot copies are displayed by default.

The list view is automatically enabled if a single Snapshot copy is specified by using the -vserver , -volume and -snapshot options together.

A preformatted query for displaying the time-related information is available by specifying the -time format specifier. This displays a table that contains the following fields for all the available Snapshot copies:

Vserver name
Volume name
Snapshot copy name
Creation time

By using the -fields option you can choose to print only the certain fields in the output. This presents the selected fields in a table view. This is ideal when you want additional information to be different from the information that is provided by the default table view, but would like it in a format which is visually easy to compare.

You can specify additional parameters to display the information that matches only those parameters. For example, to display information only about Snapshot copies of the load-sharing volumes, run the command with the -volume-type LS parameter. If you specify multiple filtering parameters, only those Snapshot copies that match all the specified parameters are displayed.

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.
| [-time ]: If the -time format is specified, the command displays time related information about all entries.
| [-instance ] }: If you specify the -instance parameter, the command displays detailed information about all fields.
[-vserver <vserver name>] - Vserver: If you use this parameter, the Snapshot copies located only on the specified Vserver will be displayed.
[-volume <volume name>] - Volume: If you use this parameter only Snapshot copies located on the specified volume will be displayed.
[-snapshot <snapshot name>] - Snapshot: If you use this parameter only Snapshot copies matching the specified name will be displayed.
[-dsid <integer>] - Snapshot Data Set ID: If this parameter is specified, the command displays information only about the Snapshot copy that has the specified data set ID.
[-msid <integer>] - Snapshot Master Data Set ID: If this parameter is specified, the command displays information only about the Snapshot copy that has the specified master data set ID.

[-size {<integer>[KB|MB|GB|TB|PB]}] - Snapshot Size: If this parameter is specified, the command displays information only about the Snapshot copies that have the specified size. The size is specified as a character specifying the unit of measurement after a number specifying the size in the mentioned unit of measurement: k (kilobytes), m (megabytes), g (gigabytes), or t (terabytes). If the unit of measurement is not specified, bytes are used as the unit, and the specified number is rounded up to the nearest 4 KB. You may also use an inequality such as >10 MB as input.
[-blocks <percent>] - Percentage of Total Blocks: If this parameter is specified, the command displays information only about the Snapshot copies that have the specified percentage of total blocks on their parent volumes. You may also use an inequality such as >10 as input.
[-usedblocks <percent>] - Percentage of Used Blocks: If this parameter is specified, the command displays information only about the Snapshot copies that have the specified percentage of used blocks on their parent volumes. You may also use an inequality such as >10 as input.
[-cpcount <integer>] - Consistency Point Count: If this parameter is specified, the command displays information only about the Snapshot copies that have the specified number of consistency points. You may also use an inequality such as <100 as input.
[-comment <text>] - Comment: If this parameter is specified, the command displays information only about the Snapshot copies that have the specified comment text. You may also specify an inequality such as !"-" as input.
[-fs-version <text>] - File System Version: If you use this parameter the only Snapshot copies displayed are those that were created when the file system was of a specific release. This parameter is helpful especially when you need to upgrade to newer software release and want to know the Snapshot copies that will be impacted by the upgrade process.

Examples

The following example displays default information about all Snapshot copies of a volume named vol1:

cluster1::> volume snapshot show -volume vol1
                                                                 ---Blocks---
