Constructor Details

Class Method Details

.add(client, storage_system, volume_name, is_shareable = false, options = {}) ⇒ OneviewSDK::Volume

Deprecated.

Use #add instead.

Note:

Volumes can be added only on the storage system and storage pools managed by the appliance.

Initiates a process to import a volume (created external to OneView) for management by the appliance.

Parameters:

  • client (OneviewSDK::Client) —

    The client object for the OneView appliance.

  • storage_system (OneviewSDK::StorageSystem) —

    The storage system in which the volume exists to be managed.

  • volume_name (String) —

    The name of the volume on the actual storage system.

  • is_shareable (Boolean) (defaults to: false) —

    Describes if the volume is shareable or private.

  • options (Hash) (defaults to: {}) —

    The options to create a volume.

Options Hash (options):

  • :name (String) —

    The name for new volume.

  • :description (String) —

    The description for new volume.

Returns:

  • (OneviewSDK::Volume) —

    The volume imported.

Raises:

#create_from_snapshot(snapshot_name, properties, volume_template = nil, is_permanent = true) ⇒ OneviewSDK::Volume

Note:

Volumes can only be created on storage pools managed by the appliance.

Creates a new volume on the storage system from a snapshot of a volume.

Parameters:

    Storage Pool to use for snapshots.

  • volume_template (OneviewSDK::VolumeTemplate) (defaults to: nil) —

    The Volume Template resource.

  • is_permanent (Boolean) (defaults to: true) —

    If true, indicates that the volume will persist when the profile using this volume is deleted.

Options Hash (properties):

  • :provisioningType (String) —

    The provision type. Values: Full or Thin.

  • :name (String) —

    The name for new volume.

  • :isShareable (String) —
