Add volumes

Use the following procedure to add volumes. Dell Technologies highly recommends giving each volume a meaningful name associated with its operational role.

Prerequisites

There must be at least three SDS nodes in the system and there must be sufficient capacity available for the volumes.

About this task

PowerFlex objects are assigned a unique ID that can be used to identify the object in CLI commands. The default name for each volume object is its ID. The ID is displayed in the Volumes list or can be obtained using a CLI query. Define each volume name according to the following rules:

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

To add one or multiple volumes, perform these steps:

Steps

  1. On the menu bar, click Block > Volumes.
  2. Click + Create Volume.
  3. In the Create Volume dialog box, configure the following items:
    1. Enter the number of volumes to be created.
      • If you type 1, enter a name for the volume.
      • If you type a number greater than 1, enter the Volume Prefix and the Starting Number of the volume. This number will be the first number in the series that will be appended to the volume prefix. For example, if the volume prefix is Vol%i% and the starting number value is 100, the name of the first volume created will be Vol100, the second volume will be Vol101, and so on.
    2. Select either Thin (default) or Thick provisioning options.
    3. Enter the volume size in GB (basic allocation granularity is 8 GB).
    4. Select a storage pool.
  4. Click Create.
  5. Verify that the operation has finished and was successful, and click Dismiss.

Next steps

To use the created volume, you must map it to at least one host. If the restricted SDC mode is enabled for the system, you must approve SDCs prior to mapping volumes to them.
