Solaris

Hi ,

I am new into solaris , need to know what a system Controller is , what it exactly does. Is it available in all Sun boxes or only on High end servers.
Is it similar to the Linux console in AIX boxes .

Thanks !!!

IF someone could point me a link , that would also be nice , i did some googling but in vain.

Thanks...

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.

In short, system controller is a controller that controls the system

Many thanks sbk1972 for the reply.
Thanks incredible for your review !!

One more doubt, If sc is down will that affect the running domains in anyway or is it just for monitoring... i guess , we can access an sc & gain access to the running domains just as we connect directly to the console.

How relevant is this sc , will the box work without these...

Again thanks for the doc link , let me go through that.....


Cheers !!!

The box will still work. Example lets talk about RSC for example, even if its not configured or its hanged for some reason, your services running on the OS will still cont working. No impact

Thanks Bro ..for your prompt response !!!
