Types ¶

type ISCSI ¶

type ISCSI struct {
	// contains filtered or unexported fields
}

func New ¶

func New(controllers []string) (*ISCSI, error)

func (*ISCSI) AddVolume ¶

func (i *ISCSI) AddVolume(ctx context.Context, iqn Iqn, volCfg *common.VolumeConfig) (*ResourceConfig, error)

func (*ISCSI) Create ¶

func (i *ISCSI) Create(ctx context.Context, rsc *ResourceConfig) (*ResourceConfig, error)

Create creates an iSCSI target according to the resource configuration described in rsc. It automatically prepends a "cluster private volume" to the list of volumes, so volume numbers must start at 1.

func (*ISCSI) Delete ¶

func (i *ISCSI) Delete(ctx context.Context, iqn Iqn) error

func (*ISCSI) DeleteVolume ¶

func (i *ISCSI) DeleteVolume(ctx context.Context, iqn Iqn, lun int) (*ResourceConfig, error)

func (*ISCSI) Get ¶

func (i *ISCSI) Get(ctx context.Context, iqn Iqn) (*ResourceConfig, error)

func (*ISCSI) List ¶

func (i *ISCSI) List(ctx context.Context) ([]*ResourceConfig, error)

func (*ISCSI) Start ¶

func (i *ISCSI) Start(ctx context.Context, iqn Iqn) (*ResourceConfig, error)
