IBM xSeries 440 8687, Hardware Maintenance Manual

Page: 33 / 258

v Each server must have two SMP Expansion modules. Each SMP Expansion
module must have four Intel Xeon MP microprocessors and at least four DIMMs.
v The Remote Supervisor Adapters on each server must be connected to an
Enterprise Network, or to each other with an Ethernet crossover cable, prior to
merging the two servers.
v You must connect a ps/2 keyboard to the primary server. Do not connect a USB
keyboard when two servers are connected in a 16-way configuration.
v
When two servers are connected in a 16-way configuration and no video device
is connected to the secondary server an error beep code might be heard during
startup. This is an acceptable action.
v If two servers are cabled together, the scan order will be the primary server, then
the secondary server. The PCI slots are scanned in the following order: PCI-X
slots 1, 2, 3, 4, 5, 6 in the primary server then PCI-X slots 7, 8, 9, 10, 11, 12 in
the secondary server.
Important: This PCI-X scan order differs from the one described in the other
xSeries 440 publications that came with your server.
16-way terms
This section provides definitions for terms that are specific to the 16-way
configuration.
Static partition: A static partition is configured through the partition descriptor found
in BIOS. This static partition defines how the servers are connected to share their
resources.
Partition descriptor: A partition descriptor defines one server as the secondary
server and the other as the primary.
Primary server: A primary server is the startup server. This server has control of
the resources assigned to both servers and retains the error logs.
Secondary server: This server is controlled by the primary server.
Installing a 16-way configuration
This section provides the basic information that is needed to install an xSeries 440
16-way configuration.
Important: The steps in this section are intended for the authorized IBM service
representative.
Configuring the static partition
If you have not already done so, install both xSeries 440 servers in the same rack
cabinet. You must install the primary server directly above the secondary server.
See the Rack Installation Instructions to install your servers, but do not connect any
signal or device cables except power.
Notes:
1. Before you can create or delete a static partition, the Remote Supervisor
Adapters must connect to a network or to each other with an Ethernet crossover
cable. This connection is needed so that the Remote Supervisor Adapters can
communicate and perform the necessary functions for the two servers to merge
or unmerge.
