Solaris

Serial Number you can get by below commands.
eeprom -v | grep Serial
showplatform -v
sneep -v

the commands only work if you've entered the serial number before with the sneep tool. and showplatform is an "lom" command. the 280r doesn't have an "lom"! so, without entering the number yourself there is NO command to see the serialnumber of a sun box!

btw. the last answer to this thread is over 2 years old...

Sneep has been updated to find the serial number on many of the more recent platforms which have "hardware" support for the chassis (product) serial.
( Unfortunately, that does not include the 280R.)

Now, getting the serial from sneep does not necessarily imply that you have had to set it manually yourself.



Sneep has also moved -
the Sun Download Center insists on having a new URL for every update of a package.


For more information and to download sneep, see http://www.sun.com/sneep ... Sun Sneep - Serial Number in EEPROM

The new URL should not change, as it will forward you to whatever the current download URL is.

The new updates for sneep can find the serial on many Sun and x86 platforms without entering it yourself. [ Many of the newer platforms support this, and future Sun machines will be required to provide a software-accessible serial.]
The 280 is not one of these systems, so it is true that there is still no way to see the serial on a Sun 280R without entering it into sneep or somewhere else.

As for the posting being over 2 years old, there is no time limit on being helpful, and new people looking for answers to similar questions come across these old posts all the time. So thanks for continuing to update the information here.

So am I, and if someone will post an example of the invocation of the command and its output, I will see about using it as a serial source in an update to sneep.
