Disk Namespace

The disk namespace has 12 commands and is based on disk management functions found in the SCALE API and web UI. It provides access to disk management methods through the disk commands.

Disk Commands

The following disk commands allow you to view and edit disk properties.

You can enter commands from the main CLI prompt or from the disk namespace prompt.

The SCALE CLI guide is a work in progress! New namespace and command documentation is continually added and maintained, so check back here often to see what is new!

Interactive Argument Editor (TUI)

Enter the -- flag following any CLI command to open the interactive arguments editor text-based user interface (TUI).
Click for more information
The interactive argument editor is a text user interface (TUI) that can help enter complex commands with multiple configurable properties. It shows expected properties, defaults, input types (string, boolean, integer, or array), and can include command instructions or warnings.
Optional properties, indicated by the # symbol, are disabled by default. Required properties are enabled. Do not disable properties that are enabled by default.
To configure required properties, enter a space after the colon then add the value.
To enable optional properties, delete # from the corresponding line.
Some required properties are disabled if they are part of a pair of properties where one or the other is required. Select one property to enable and enter a value.
Press F2 or click Save to save the modified file.
Press F10, Esc, or click Quit to exit the TUI. The command automatically executes upon exit.

Get_Instance Command

The get_instance command returns all the settings for a specified disk.

Use the query command to locate the identification number for system disks.

Using the Get_Instance Command

Description

The get_instance command has one property, id. Enter the entire string listed as the identifier in the query command output for the identifier property value. Enter the property argument using the = delimiter separating the property and double-quoted value. Enter the command then press Enter. The command returns a table containing the identifier, name, subsystem, number, serial, lunid, size, description, transfermode, hddstandby, advpowermgmt, togglesmart, smartoptions, expiretime, passwd, critical, difference, informational, model, rotationrate, type, kmip_uid, zfs_guid, bus, exported_zpool, unsupported_md_devices, duplicate_serial, enclosure, partitions, add devname properties for the specified disk.

Usage

From the CLI prompt, enter:

storage disk get_instance id="diskidentifier"

Where diskidentifier is the identifier of the disk you want to view.

Resize Command

The resize command allows you to resize disks to a specific size in gigabytes.

Use the query command to locate the name for system disks.

Using the Resize Command

Description

The resize command has one required property, disks, and two optional properties, sync, and raise_error. See Resize Properties below for details. Enter the command string then press Enter. The command returns completion percentages when successful.

Resize Command Properties

Property	Required	Description	Syntax Example
`disks`	Yes	Use to specify the disks and size (optional) in gigabytes. Enter the `name` property argument using `:` to separate double-quoted property and value. Separate multiple disk values with a comma. Enter the `size` property argument using `:` to separate double-quoted property and value. The default value for `size` is null. Enclose both `name` and `size` in curly brackets `{}`. If `size` is smaller than the physical space available on the disk, the remaining space is reserved for over-provisioning. If `size` is not given, the disk reverts to its original size (un-overprovision).	`disks={“name”:"diskname1","diskname2", “size”:"number"}`
`sync`	No	Enter `true` to synchronize new sizes of the disks with the database cache. The default is true.	`sync=true` or `sync=false`
`raise_error`	No	Enter `true` to set the disk(s) to raise a CallError upon failure, or `false` to only log errors. The default is false.	`raise_error=true` or `raise_error=false`

Usage

From the CLI prompt, enter:

storage disk resize disks={“name”:"diskname1,diskname2", “size”:"number"} sync=true/false raise_error=true/false

Where:

diskname1 and diskname2 are the names of the disk you want to resize.
number is the size (in gigabytes) to resize the disk(s) to.
true/false in the sync property enables or disables synchronizing the new size of the disk(s) with the database cache.
true/false in the raise_error property sets whether the disk(s) raise a CallError upon failure (true) or only log errors (false).

Command Example

storage disk resize disks={"name":"sda,sdb", "size":"894"} sync=true raise_error=false
[0%] ...
[100%] ...

Retaste Command

The retaste command forces the system to re-read specified disks and update their data.

Use the query command to locate the identification number for system disks.

Using the Retaste Command

Description

The retaste command has one required property, disks. Enter the disks property argument using = to separate property and value. Separate multiple disks with a comma. Enter the command string then press Enter. The command returns completion percentages when successful.

Usage

From the CLI prompt, enter:

storage disk retaste disks=name1,name2

Where name1 and name2 are the names of the disks you want to retaste.

Command Example

storage disk retaste disks=sdl
[85%] Retasting disks...
[95%] Waiting for disk events to settle...
[100%] Retasting disks done...
SUCCESS

Smart_Attributes Command

The smart_attributes command returns S.M.A.R.T. attributes values for specified disk.

Use the query command to locate the identification number for system disks.

Only devices with the ATA bus type support S.M.A.R.T. attributes.

Using the Smart_Attributes Command

Description

The smart_attributes command has one required property, disks, which specifies the disk you want to view S.M.A.R.T. attributes for. Enter the property argument using = to separate property and value. Enter the command string then press Enter. The command returns a table with S.M.A.R.T. attributes when successful.

Usage

From the CLI prompt, enter:

Temperature Command

The temperature command returns the temperature of a specified disk.

Use the query command to locate the identification number for system disks.

Using the Temperature Command

Description

The temperature command has two required properties, name and options. options has two required properties, cache and powermode. See Temperature Command Properties below for details. Enter the command string then press Enter. The command returns a temperature (in Celsius) when successful.

Temperature Command Properties

Property	Required	Description	Syntax Example
`name`	Yes	Use to specify the disk to see temperature for. Enter the `name` property argument using `:` to separate double-quoted property and value. Separate multiple disk values with a comma. Enter the `size` property argument using `:` to separate double-quoted property and value. The default value for `size` is null. Enclose both `name` and `size` in curly brackets `{}`.	`disks={“name”:"diskname1","diskname2", “size”:"number"}`
`options`	Yes	Use to retrieve previous temperatures for the disk by specifying how far back in seconds to go in the cache and to specify the power mode to apply. `cache` specifies the number of seconds to go in the cached temperature values to go to retrieve information. Enter the number property argument using `:` to separate double-quoted property and value. The default is null which returns the current temperature. `powermode` specifies the S.M.A.R.T. power mode to apply: `NEVER` where the device is fully powered up and ready to send/receive data. The disk only undergoes S.M.A.R.T. tests when powermode is set to `NEVER`. The default value is `NEVER`. `IDLE` where the disk completes commands slower than when set to `NEVER` but uses less power. `STANDBY` where the disk completes commands slower than when set to `IDLE` but uses less power. `SLEEP` where the disk does not complete commands until reset. Uses the least amount of power. Enter property argument enclosed in curly brackets `{}`, with both `cache` and `powermode` using `:` to separate double-quoted properties and values, and each argument is separated with a comma.	`options={“cache”="numberofseconds",“powermode”:"NEVER"}`

Usage

From the CLI prompt, enter:

storage disk temperature name=diskname options={“cache”:"seconds",“powermode”:"MODE"}
