Ces System - IBM RS/6000 SP Handbook

10.4.3 CES system

If you want to manage Enterprise Servers from a single point of control, you have
to integrate these servers into a CES system, adding a CWS to your servers and
install PSSP on all of them. Within the CES system, the Enterprise Servers can
be configured to use the SP Switch (the SP Switch2 is not supported).
The Enterprise Servers can be new Enterprise Servers or existing Enterprise
Servers.
CES system with new Enterprise Servers
In this case, you install your CES system from scratch. Your Enterprise Servers
are either newly obtained or you do not care about the software previously
installed on them. Use the steps described in Chapter 2, "Installing and
Configuring a New RS/6000 SP System" in IBM Parallel System Support
Programs for AIX: Installation and Migration Guide, GA22-7347 to install this
type of system.
For example, we consider the installation of a CES system with one CWS and
two M/T 7017 Enterprise Servers (SAMI port: /dev/tty0 and S1 port: /dev/tty1 on
frame 1, respectively SAMI port: /dev/tty2 and S1 port: /dev/tty3 on frame 2).
In order to initate "Step 29: Enter Frame Information and Reinitialize the SDR"
described in Chapter 2, "Installing and Configuring a New RS/6000 SP System"
of the IBM Parallel System Support Programs for AIX: Installation and Migration
Guide, GA22-7347, you would use the command for our example as
spframe
follows:
# spframe -p SAMI -r yes 1 2 /dev/tty0
With this command, you added two Enterprise Servers as frames 1 and 2 and
initialized the SDR.
You can assign any frame number to a frame as long as the number is between
1 and 128, inclusively. It is not necessary to start from frame 1. Also, the
sequence of frame number assignment does not matter.
For example, if you have three Enterprise Servers, you can add them to your
CES system one by one, in any order. You could add frame 28 first, frame 9
second, and then frame 57 third.
Instead of using the spframe command, you can use SMIT menus for these
operations.
If you are considering migrating your CES system to an SP system in the future,
you have to use the -n flag on the spframe command and consider switch port
numbers for that environment.
