6.4.3 S70 Enterprise Server

In this scenario, we have an SP frame with two high nodes and an SP Switch2 in

Cluster 1600. We add one S70 as a SAMI attached node to Cluster 1600.

Hardware considerations

Before you integrate a pSeries p680 or an Enterprise Server 7017-S70, S80, or

S85 into a Cluster 1600, a special SAMI interface (FC 3150, FC 3151) must be

integrated into the machine. This provides the connection to the serial port of the

CWS for hardware control, and the first integrated serial line is connected to the

CWS for use by

s1term. Additionally, you have to provide a management

Ethernet adapter, which has to be in slot 1.

Integrating a SAMI protocol server

Example 6-29 shows the initial configuration of our Cluster 1600.

Tip: We recommend upgrading the firmware of the S70 and S7A to at least

20020514 (Sys) and 20010824 (SvP), and for the 7017-S80 and S85 and the

p680 to at least 20020411 (Sys) and 20020411 (SvP).

The following steps highlight what is unique to these external nodes:

1. SAMI attached nodes require an extra serial connection, one to the SAMI

card and one to the integrated serial port. The SAMI connection is for talking

to the supervisor card and the other for console login. We prepared these

connections and the connection to the SP LAN. Each SAMI attached node is

seen as an individual frame containing one node. Example 6-30 shows us

adding the new frame.

Example 6-30 Adding the CSP frame

– spmon -d shows the node type as extern.

–

splstdata -f shows the hardware_protocol as SAMI.

–

splstdata -n lists basic node configuration information.

2. The next step is to configure the SP LAN information. Example 6-31 on

page 165 shows this information being added with the

spadaptrs command.
