Use the vSphere
PowerFlex plug-in to add devices to an SDS in
PowerFlex.
About this task
In a DirectPath-based system, you add devices only after the deployment. In an RDM/VMDK-based
PowerFlex, you can add devices during and after the deployment.
You can add a Storage device or an Acceleration device to an SDS or to all SDSs in the system. For a Storage device, you must define the Storage Pool and Media Type for each device you add. For Acceleration device, you must select the Acceleration Pool (which may be RFCache or NVDIMM) for each device added. For Fine Granularity (FG), an Acceleration device must be configured with NVDIMM. For more information on FG, see "Data layout" in the
Getting to Know Guide.
All data on added devices will be erased.
NOTE:If you intend to enable zero padding on a Storage Pool, you must do so before you add any devices to the Storage Pool.
Steps
From the
SDSs screen of the
PowerFlex plug-in, select one of the following:
Right-click a specific SDS, and then select
Add devices to a single SDS.
Right-click any SDS, and then select
Add devices to
PowerFlex system.
The
Add Device
dialog box is displayed. All devices that can be attached to the selected SDS are listed. For the system view, all SDSs are listed, and you can choose devices to add for each SDS. It may take a few moments to load the list of devices from the vCenter.
