Creating a Disk Domain

Creating a Disk Domain

Storage systems provide storage space based on disk domains. When creating a disk domain, specify the disk type and quantity.

Context

  • You are advised to use different disk domains to create storage pools for the block storage service and file storage service.
  • To prevent data loss or performance deterioration caused by a member disk failure, a storage system uses hot spare space to take over data from the failed member disk. For details about how to plan hot spare policies for a disk domain, see "Planning Disk Domains".

Procedure

  1. Log in to DeviceManager.
  2. Choose Provisioning > Disk Domain.
  3. Click Create.

    The Create Disk Domain dialog box is displayed.

  4. Specify Name and Description for the disk domain.

    The descriptive information, such as the function and properties of the disk domain, helps identify the disk domain.

  5. Select the disks that comprise the disk domain. There are three ways to select the disks:

    • Select All available disks.

      You only need to configure the hot spare policy for the storage tier.

    • Select Specify disk type.
      1. Select the storage tier according to the disk type.
      2. Configure the number of disks for each storage tier.
      3. Configure the hot spare policy for each storage tier.
    • Select Manually select.
      1. Click Select.
      2. In the Select Disk dialog box, select the disks you need and click .
      3. Click OK to finish selecting disks.
