Dell PowerFlex v3.6.x CLI Reference Guide

add_volume

Add a volume to the PowerFlex system.

You can create a volume when the requested capacity is available and system capacity is balanced. To start allocating volumes, at least three SDS nodes must be configured in the system.

The created volume cannot be used until it is mapped to at least one SDC.

Syntax

scli --add_volume (((--protection_domain_id <ID> | --protection_domain_name <NAME>) --storage_pool_name <NAME>) | --storage_pool_id <ID>) --size_gb <SIZE> 
  [--volume_name <NAME>] 
  [--compression_method none | normal]
  [--thin_provisioned | --thick_provisioned | <BLANK>] 
  [--use_rmcache | --dont_use_rmcache | <BLANK>]

Parameters

--protection_domain_id <ID>: Protection Domain ID
--protection_domain_name <NAME>: Protection Domain name
--storage_pool_name <NAME>: Storage Pool name
--storage_pool_id <ID>: Storage Pool ID
--size_gb <SIZE>: Volume size, in GB. Basic allocation granularity is 8 GB.
--volume_name <NAME>: Name to be associated with the added volume
--compression_method {none | normal}: Indicates the compression method to be used, relevant only for fine granularity data layouts.
--thin_provisioned | --thick_provisioned | <BLANK>: Specifies whether the specified volume will be thin provisioned or thick provisioned (the default). If left blank, the default of the Storage Pool will be used (thick provisioned for medium granularity, thin provisioned for fine granularity).
--use_rmcache | --dont_use_rmcache | <BLANK>: Specifies whether the specified volume will use Read RAM Cache for caching. Default: --use_rmcache. If left blank, use the value of the Storage Pool.

NOTE:If you use the storage_pool_id parameter in the command, you do not need to also specify the Protection Domain ID or name, and the Storage Pool name.

Example

scli --mdm_ip 192.168.1.200 --add_volume --size_gb 8 --volume_name vol_1 --protection_domain_name pd1 --storage_pool_name sp1

Volume names

Assign each volume a meaningful name associated with its operational role. When a name has not been defined, the system may display default system-defined names that use the volume’s ID.

Each volume name should conform to the following rules:

Contains fewer than 32 characters
Contains only alphanumeric and punctuation characters
Is unique within the object type

NOTE:PowerFlex objects are assigned a unique ID that can be used to identify the object in CLI commands. You can retrieve the ID via a query or through the object’s property sheet in the PowerFlex GUI.
