Issuing commands for LDEVs within a LUSE device
A LUSE device is a group of LDEVs regarded as a single logical unit. Because
it is necessary to know the configuration of the LDEVs when issuing a
command, a new command is used to specify a target LU and acquire LDEV
configuration data, as shown in the following figure.

HORCM operational environment
The HORCM operates as a daemon process on the host server and is
activated either automatically when the server machine starts up or manually
by the startup script. HORCM reads the definitions specified in the
configuration file upon startup. The environment variable HORCM_CONF is
used to define the location of the configuration file to be referenced.
