storage subsystem to set the correct host type first. The server will then be able to
recognize the storage subsystem correctly for host-agent (in-band) management.
Host-agent (in-band) management method:
To use this method, host-agent software must be installed on the host server. Using
the host-agent software, you can manage the storage subsystem through the
Storage Manager software client program by using the same 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. The client software is installed on
the management station. Figure 44 shows the host-agent (in-band) management
method.
Direct (out-of-band) management method:
This method contains information about Ethernet connections from a management
station to each controller in the storage subsystem. You must install at least one
management station. The management station can be the host or a workstation on
the Ethernet network. The client software is installed on the management station.
Attach Ethernet cables to each management station (one pair per storage
subsystem). You will connect the cables to each storage subsystem controller later
when you install the storage subsystem. Figure 45 on page 58 shows the direct
(out-of-band) management method.
Note: Do not connect the DS3500 storage subsystem Ethernet ports to a public
network or public subnet. To minimize security risks, create a private network
between the DS3500 storage subsystem and the management station.
