Cable the network

Use the information in this section to understand the basic concepts of cabling the network after you

have installed and configured the iSCSI HBA.

Once the xSeries or blade system has been configured, the network needs to be cabled to complete the

configuration. The first step is to locate the ports that need to be cabled into the network.

Before you cable the network locate each point or port that you will connect from the following:

v The i5/OS partition network interface; either a new adapter or an existing adapter being used for a

TCP/IP connection.

v The xSeries or blade server service processor. Depending on which server you are attaching the

location of the service processor will vary. You will need to refer to your xSeries or blade server

documentation to complete this connection.

– For xSeries the RSA II or the BMC might be used as the service processor.

– For blade servers located in a BladeCenter the management module is used as a service processor.

v The iSCSI HBA connection is as follows:

– In the i5/OS partition and the xSeries the port to connect to is located on the tailstock of the iSCSI

adapter.

– In the blade server the port to connect is located on the module plugged into I/O bay number 3.

This might be an internally wired port on an integrated switch or a fan-out cable from a

pass-through module. Refer to the I/O module documentation to complete this connection.

There are many different ways to cable the network – the iSCSI configuration could even be added to an

existing Ethernet network. All the possibilities won't be covered here. There are a couple of important

considerations that must be observed when cabling the iSCSI configuration:

v Ensure all iSCSI HBAs in both the System i5

network.

v Ensure the System i5 model network interface card and the service processor connection reside in the

same network.

For help understanding different external switch considerations see Ethernet switches for iSCSI.
