Hi,

System controllers are best thought of as little pc's that monitor the health of the chassis. Within high end servers, F15 / F25 / 4800 / 6800 and lots of others, you have individual domains running solaris. These domains are monitored by the SC controller.

SC controllers come in pairs, one being the master, the other the slave, all to ensure redundancy in the event of a hardware problem.

What you might be getting confused with are Loms / Aloms. Advanced Lights Out management are internal `cards` that allow you to connect on to and be able to switch off / on the server. This is tremendous is the server is located miles away in a dark data centre, i.e. not supported.

So, SC controllers are small little pc's / nodes running a form of os ( older versions ) or reduced version of solaris, that controll the operation / booting of configured domain(s) within a high end chassis. Like a Matron in control of several hopstial wards.

Lom / Aloms are individual cards, installed into any server, that allows you to switch on / off, monitor the health of the physical server.

loms :- docs.sun.com/source/817-5233-10/lomsolaris.html

Sc :- docs.sun.com/source/817-3951-12/chp11.html

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.

       See attributes(5) for descriptions of the following attributes:
