Chapter 4. Installing the Device Driver on the RS/6000 SP System
For an RS/6000 SP system, the installation tasks must be performed on each node.
You must make the installation files available and then install them on all the relevant
nodes. This chapter discusses the following tasks to enable you to install the device
driver on the RS/6000 SP system:
v Checking System Prerequisites
v Installing Software on the Control Workstation
v Installing Device Drivers on the SP Nodes
Perform the following tasks on the Control Workstation. You should not need to telnet
or rlogin to the individual SP System nodes. If you are unfamiliar with the dsh
command, refer to one of the following Parallel System Support Program (PSSP)
publications:
v Parallel System Support Program for AIX: Administration Guide
v Parallel System Support Program for AIX: Command and Technical Reference
If you cannot use the dsh command because of the setup at your site, then use the
telnet command to each node. Then perform the steps below, beginning with step 5,
and omitting the dsh prefix.
Checking System Prerequisites
To check system prerequisites, perform the following:
__ 1. Log into the Control Workstation as a root user.
__ 2. To go to a temporary directory, type cd /tmp at the system prompt, and then
__ 3. Make a working collective file containing a list of the relevant nodes on which
__ 4. To test the working collective file, type dsh date, and then press Enter. The
press Enter.
you want to perform the update. Type the following, pressing Enter after each
line:
cat > group1
nodename1
nodename2
nodename3......
CTRL-D
export WCOLL=/tmp/group1
result should look similar to the following:
nodename1:
Wed Apr 10 10:37:46 EDT 1999
nodename2:
Wed Apr 10 10:37:46 EDT 1999
nodename3:
Wed Apr 10 10:37:47 EDT 1999
nodename4:
Wed Apr 10 10:37:48 EDT 1999
If not, examine your nodelist file ./group1 to ensure that the node names are
correct. Also ensure that the Kerberos ticket is current to permit dsh to be
performed. If not, you may need to refresh it. Contact your system administrator
