Types

type DriveManager

type DriveManager interface {
	// GetDrivesList gets list of drives
	GetDrivesList() ([]*api.Drive, error)
	// Locate manipulates of drive's led state, receive drive serial number and type of action
	// returns current led status or error
	Locate(serialNumber string, action int32) (currentStatus int32, err error)
	// LocateNode manipulates of node's led state, which should be synced with drive's led
	LocateNode(action int32) error
	// GetDriveSmartInfo gets smart info for specific drive with given serialNumber
	GetDriveSmartInfo(serialNumber string) (string, error)
	// GetAllDrivesSmartInfo gets smart info for all drives on given node
	GetAllDrivesSmartInfo() (string, error)
}

DriveManager is the interface for managers that provide information about drives on a node

type DriveServiceServerImpl

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

DriveServiceServerImpl is the implementation of gRPC server that gives possibility to invoke DriveManager's methods remotely

func NewDriveServer

func NewDriveServer(logger *logrus.Logger, manager DriveManager) DriveServiceServerImpl

NewDriveServer is the constructor for DriveServiceServerImpl struct Receives logrus logger and implementation of DriveManager as parameters Returns an instance of DriveServiceServerImpl

func (*DriveServiceServerImpl) GetAllDrivesSmartInfo

func (svc *DriveServiceServerImpl) GetAllDrivesSmartInfo(ctx context.Context, req *api.Empty) (*api.SmartInfoResponse, error)

GetAllDrivesSmartInfo invokes DriveManager's GetAllDrivesSmartInfo() and sends the response over gRPC Receives go context and Empty message Returns SmartInfoResponse with smart info json string

func (*DriveServiceServerImpl) GetDriveSmartInfo

func (svc *DriveServiceServerImpl) GetDriveSmartInfo(ctx context.Context, req *api.SmartInfoRequest) (*api.SmartInfoResponse, error)

GetDriveSmartInfo invokes DriveManager's GetDriveSmartInfo() and sends the response over gRPC Receives go context and SmartInfoRequest which contains Serial Number Returns SmartInfoResponse with smart info json string

func (*DriveServiceServerImpl) GetDrivesList

func (svc *DriveServiceServerImpl) GetDrivesList(ctx context.Context, req *api.DrivesRequest) (*api.DrivesResponse, error)

GetDrivesList invokes DriveManager's GetDrivesList() and sends the response over gRPC Receives go context and DrivesRequest which contains node id Returns DrivesResponse with slice of api.Drives structs

func (*DriveServiceServerImpl) Locate

func (svc *DriveServiceServerImpl) Locate(ctx context.Context, in *api.DriveLocateRequest) (*api.DriveLocateResponse, error)

Locate invokes DriveManager's Locate method for manipulation drive's LED state

func (*DriveServiceServerImpl) LocateNode

func (svc *DriveServiceServerImpl) LocateNode(ctx context.Context, req *api.NodeLocateRequest) (*api.Empty, error)

LocateNode invokes DriveManager's LocateNode method for manipulation node's LED state
