Adding Devices/Device Classes

Adding Device Classes

Unify the classification of devices of the same type or hard disks with the same business logic in cluster nodes, customize device classes according to storage needs, and allocate different storage contents to different types of storage disks.

Notes

Adding device classes is not supported when the cluster type is Extend.

Procedure

  1. Enter Platform Management.

  2. In the left navigation bar, click Storage Management > Distributed Storage.

  3. Click the Device Classes tab.

  4. Click Add Device Class and configure the relevant parameters according to the following instructions.

    ParameterDescription
    NameThe name of the device class. The following names cannot be used for the device class: hdd, ssd, nvme.
    Storage DevicesSelect Blank Disks or Unformatted Disk Partitions in the node.
    • When the switch for all empty devices is turned on: add all empty devices under the node to this device class;
    • When the switch for all empty devices is turned off: manually enter the names of the empty devices under the node, for example, sda.

Adding Devices

Map available hard disks to storage devices for usage and management.

Note: Once hard disks are added as storage devices, updating or removing them through the interface is not supported.

Procedure

  1. Enter Platform Management.

  2. In the left navigation bar, click Storage Management > Distributed Storage.

  3. Click the Device Classes tab.

  4. On the right side of the device class, click Add Device, and configure the relevant parameters according to the following instructions.

    ParameterDescription
    Node TypeSelect the type of node where the hard disk you want to add as a storage device is located.
    Compute Node: A node that has not added storage devices.
    Storage Node: A node that has added storage devices.
    Add TypeSelect the method to add hard disks as storage devices.
    All Empty Disks: Choose to add all unpartitioned mounted disks in the node as storage devices.
    Specified Disks: Choose to add some disks in the node as storage devices, including empty disks or already partitioned mounted disks.
    When the node type is Storage Node, only Specified Disks can be selected.
    Specified DisksWhen the add type is Specified Disks, enter the names of all the hard disks to be added as storage devices, such as sda, sdb. After entering each hard disk name, press Enter to confirm.

    Note: It is recommended to use the entire hard disk as storage devices rather than partitions on the hard disk.

  5. Click Add.

Hard Disk Status

  • Normal: The corresponding status of the storage device is IN+UP.

  • Abnormal: The corresponding status of the storage device is IN+DOWN.

  • Offline: The corresponding status of the storage device is OUT+UP.

  • Fault: The corresponding status of the storage device is OUT+DOWN.
