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.
Depending on the controller firmware version for your subsystem, refer to the
following guides for more information about setting up in-band or out-of-band
management connections:
v IBM System Storage DS Storage Manager Version 10 Installation and Host
Support Guide (for storage subsystems with controller firmware version earlier
than 7.8x.xx.xx)
v IBM System Storage DS Storage Manager Version 10.8 Installation and Host
Support Guide (for storage subsystems with controller firmware version
7.8x.xx.xx or later)
Important: If the operating system of the host server that the storage subsystem
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.
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 DS Storage Manager client program to manage the
DS5020 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 52 on page 83 shows the host-agent (in-band)
management method.
