path while the host (on which HDLM is installed) is still running. This is called the

dynamic re-configuration function. For details on the dynamic re-configuration

function, see 4.7.1 Setting Up an Added LU and Path as an HDLM

Management-target.

The function to dynamically add an LU enables you to add an LU or a path while a

host (on which HDLM is installed) is running.
