Chapter 4. Installing the Device Driver Software on an
RS/6000 SP System

This chapter explains how to install the device driver on an AIX SP system on which AIX is already
installed.

Note:

If the adapter was installed prior to the installation of the AIX operating system, do not continue with
this section. The device driver software was automatically installed with AIX. Proceed to “Verifying
the Installation” on page 15.

Installing device drivers in an SP system is complicated by two factors. First, the SP nodes normally do
not have CD-ROM or diskette devices. Secondly, it is often necessary, or at least desirable, to install the
device drivers on multiple nodes.

To overcome the first problem, place the installable images on the SP system’s control workstation, and
then install them on the target nodes from there.

To overcome the second problem, use the

dsh

(distributed shell) command, which enables the

execution of commands on multiple nodes simultaneously. This provides significant advantage over
using

telnet

rlogin

to install the device drivers on a node-by-node basis. Refer to the

Parallel System

Support Program for AIX Administration Guide

, order number GC23-3897 or

PSSP: Command and

Technical Reference

, order number GC23-3900 for details on using the

dsh

command.

Note:

To use the

dsh

command, the Kerberos ticket for the SP system must be current. If you are unsure

whether the Kerberos ticket is current, consult the system administrator for the system on which the
installation is to occur.

To complete the installation of the device drivers on the node(s) of an SP system, perform the following
steps:

1. Set up for the

dsh

command, that is, set up the working collective file in the control workstation.

2. Check prerequisites on the system nodes by using the

dsh

command.

3. Create an installable device driver image on the control workstation.

4. Install the device drivers on the system nodes by using the

dsh

command.

If the site setup precludes the use of the

dsh

command, install the device drivers on each node

individually. To do so,

telnet

to each node and perform the steps in the various procedure sections below,

omitting the

dsh

prefix. If only a few nodes are involved, you can use the

dsh

command without using the

working collective file. Use the

-w

option to include the node names within the command. For example, to

determine the AIX level on three nodes, run the following command:

dsh -w [nodename1,nodename2,nodename3] oslevel

where the actual node names are substituted for

[nodename1], [nodename2],

and

[nodename3]

Note:

In the following instructions, brackets are used to indicate that the user must supply actual values
for input, or that the system will supply actual values for output.

Proceed with the device driver installation, starting with “Setting Up and Checking System Prerequisites”
on page 10 and perform the following tasks on the control workstation.
