list_local_disks

list_local_disks(**kwargs)

Returns a list of the gateway's local disks. To specify which gateway to describe, you use the Amazon Resource Name (ARN) of the gateway in the body of the request.

The request returns a list of all disks, specifying which are configured as working storage, cache storage, or stored volume or not configured at all. The response includes a DiskStatus field. This field can have a value of present (the disk is available to use), missing (the disk is no longer connected to the gateway), or mismatch (the disk node is occupied by a disk that has incorrect metadata or the disk content is corrupted).

Response Structure

• (dict) --
  • GatewayARN (string) --

    The Amazon Resource Name (ARN) of the gateway. Use the ListGateways operation to return a list of gateways for your account and Amazon Web Services Region.

  • Disks (list) --

    A JSON object containing the following fields:

    • ListLocalDisksOutput$Disks
    • (dict) --

      Represents a gateway's local disk.

      • DiskId (string) --

        The unique device ID or other distinguishing data that identifies a local disk.

      • DiskPath (string) --

        The path of a local disk in the gateway virtual machine (VM).

      • DiskNode (string) --

        The device node of a local disk as assigned by the virtualization environment.

      • DiskStatus (string) --

        A value that represents the status of a local disk.

      • DiskSizeInBytes (integer) --

        The local disk size in bytes.

      • DiskAllocationType (string) --

        One of the DiskAllocationType enumeration values that identifies how a local disk is used.

        Valid Values: UPLOAD_BUFFER | CACHE_STORAGE

      • DiskAllocationResource (string) --

        The iSCSI qualified name (IQN) that is defined for a disk. This field is not included in the response if the local disk is not defined as an iSCSI target. The format of this field is targetIqn::LUNNumber::region-volumeId .

      • DiskAttributeList (list) --
