Below is a list of devices that can or cannot be managed by HDLM. The
devices that can be managed by HDLM are called HDLM management-target

The following devices are from the storage systems listed in Section What
is HDLM? on page 1-2 :
¢
SCSI devices
¢
Hitachi storage system command devices, such as Hitachi RAID
Manager command devices
¢
The EMC DMX series, EMC CX series, and HP EVA series
Note that only the OSs below can be used to manage these devices.
For the EMC DMX series, EMC CX series, and HP EVA series:
- Windows Server 2003 (x86) SP1 or later
- Windows Server 2003 (IPF) SP1 or later
- Windows Server 2003 (x64)
For the EMC CX series:

System Configuration
HDLM is available in two SAN environment types: FC-SAN and IP-SAN. Note
that the EMC DMX series, EMC CX series, and HP EVA series can only be used
in an FC-SAN environment.
System Configuration Using an FC-SAN
In an FC-SAN, fiber cables connect hosts to storage systems. The cable port
on the host is called a host bus adapter (HBA). The cable port on the storage
system is called a port (P) on a channel adapter (CHA).
A logical unit (LU), which lies in a storage system, is either an input target or
an output target to or from a host. The areas within an LU are called Devs.
A route that connects a host to a Dev in an LU is called a path.
HDLM assigns a unique ID to each management-target path. This ID is called
AutoPATH_ID. Sometimes, the path is also just simply called a management
target.
