Setting Up SDS

If SDS is installed on an HDLM host, SDS uses the logical device file name of

the HDLM device to access the HDLM-managed device. Therefore, after you

install HDLM, you need to register the logical device file name of the HDLM

device. When removing HDLM, unregister the logical device file name of the

HDLM device and set the logical device file name of the sd or ssd device.

Notes

When using SDS, keep the following in mind.
