Configure and Customize Dell PowerFlex v3.6.x

Add SDSs

Add SDSs to the PowerFlex system.

Prerequisites

Ensure that at least one suitable Storage Pool is defined in the required Protection Domain. If you want to add Acceleration devices now, ensure that at least one Acceleration Pool is defined as well.

All devices in a Storage Pool must be the same media type. Ensure that you know the type of devices that you are adding to the system. Ensure that the Storage Pool to which you are adding devices is configured to receive that media type.

About this task

Device data is erased when devices are added to an SDS. When adding a device to an SDS, PowerFlex will check that the device is clear before adding it. An error is returned, per device, if it is found not to be clear. A device that has been used in the past can be added to the SDS by using the Force Device Takeover option. When this option is used, any data that was previously saved on the device will be lost. For more information, see "Configuring direct attached storage" in the Getting to Know Dell PowerFlex Guide.

You can assign a name to the SDS, as well as to the devices. This name can assist in future object identification. This can be particularly helpful for SDS devices, because the name will remain constant, even if the path changes. SDS and device names must meet the following requirements:

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

NOTE:Devices can be tested before going online. Various testing options are available the Advanced area of the window (default: Test and Activate ).

NOTE:Acceleration settings can be configured later, using the Backend > Devices By Pools view.

NOTE:You cannot enable zero padding after adding the devices. For more information, see "Storage Pools" in the Getting to Know Dell PowerFlex Guide.
