Configuring the storage subsystem

You must configure the storage subsystem configuration after you install the storage
subsystem in a rack cabinet. Use the information in the following sections to
configure your storage subsystem configuration.

Storage subsystem management methods

Before you configure the storage subsystem, determine which method of storage
subsystem management you want to use. You can manage the storage subsystems
in either of two ways: host-agent (in-band) management or direct (out-of-band)
management.
For more information on setting up in-band or out-of-band management
connections, refer to the DS4000 Storage Manager Installation and Support Guide
for the operating system of the host computer that will be used to manage the
DS4800 Storage Subsystem.
Important: If the operating system of the host server that the storage subsystem

Host-agent (in-band) management method

This method requires host-agent software that you install on the host server. The
host-agent software allows the DS4000 Storage Manager client program to manage
the DS4000 Storage Subsystem using the same fibre channel connections between
the host server and the storage subsystem. You must install at least one
management station and a software agent host. The management station can be
the host or a workstation on the Ethernet network. A management station will have
the client software installed. Figure 61 on page 83 shows the host-agent (in-band)
management method.

logical drives are mapped to is not Microsoft Windows 2000 or Server
2003, then you have to make a direct (out-of-band) management
connection to the storage subsystem to set the correct host type first.
Then, the server will be able to recognize the storage subsystem
correctly for host-agent (in-band) management.
