How would you find out what version of Solaris is currently running?

more /etc/release

use the command " uname -r " to check the release and version of sun OS

Run the command showrev. There's a man page on showrev and there are switches to help you do whatever you're trying to do

uname -r

USe Banner in OBP.

It will give the complete information about the server.

uname -X

Don't think the OBP will help will it? I mean, isn't that before the operating system is loaded?

OBP would not help any in this regards, as OBP show the BOOTPROMPT version not the Solaris version.

uname-

     -r              Prints the operating system release level.

     -s              Prints the name  of  the  operating  system.
     -v              Prints the operating system version.

     -X              Prints  expanded  system  information.

uname -x or in use banner

cat /etc/release

uname -X
