Connecting the Management Host

C H A P T E R 3

This chapter describes Sun StorageTek 2500 Series Array cable connections for hosts. It contains the following sections:

Connecting the Management Host

Connecting the Management Host

The management host directly manages Sun StorageTek 2500 Series Arrays over an out-of-band network. This section describes how to setup an out-of-band connection between the Ethernet port of a controller (FIGURE 3-1) and the management host.

FIGURE 3-1 Ethernet Ports for Controller A and Controller B

Figure showing the Ethernet ports for Controller A and Controller B.

Note - Before you begin, ensure that the two required Ethernet cables are available. These requirements are outlined in the StorageTek 2500 Series Array Site Preparation Guide.

There are three ways to establish a connection between the management host and Ethernet port 1 of a controller module:

Attaching the Ethernet Ports to the LAN of the Management Host

Attaching the Ethernet Ports to the Management Host Using an Ethernet Hub

Attaching the Ethernet Ports Directly to the Management Host With a Cross-Over Cable

Attaching the Ethernet Ports to the LAN of the Management Host

To attach the Ethernet ports to the local area network (LAN) of the management host:

1. Locate the Ethernet port for Controller A and Controller B at the back of the controller tray (FIGURE 3-1).

2. Connect Ethernet cables to the Ethernet ports of each controller.

3. Connect the other end of each Ethernet cable to the LAN on which your management host resides (preferably on the same subnet).

Attaching the Ethernet Ports to the Management Host Using an Ethernet Hub

To attach the Ethernet ports and the management port Ethernet interface to an Ethernet hub on a private subnet:

1. Locate Ethernet ports on Controller A and Controller B at the back of the controller tray (FIGURE 3-1).

2. Connect Ethernet cables to the Ethernet ports of each controller module.

3. Connect the other end of each Ethernet cable to an Ethernet hub.

4. Connect an Ethernet port on the management host to the Ethernet hub.

Attaching the Ethernet Ports Directly to the Management Host With a Cross-Over Cable

Note - This method would typically be used only to establish temporary IP connectivity between the management host and the controller’s Ethernet ports.

To attach the Ethernet ports directly to the management host using cross-over cables:

1. Locate the Ethernet ports for Controller A and Controller B at the back of the controller tray (FIGURE 3-1).

2. Obtain and connect Ethernet cross-over cables to the Ethernet port of each controller module.

3. Connect the other end of each Ethernet cable directly to your management host Ethernet ports.
