How to find Firmware revision ?

I am having a Sun-Fire-T2000 server which is having Solaris OS running on it.

I am not able to find an exact Firmware version. Please suggest something.

sc> showhost
Host flash versions:
   OBP 4.30.4 2009/08/19 07:24
   Hypervisor 1.7.3.a 2009/10/29 15:50
   POST 4.30.4 2009/08/19 07:47
sc>
root@abc:>prtdiag -v | grep -i system
System Configuration:  Sun Microsystems  sun4v Sun Fire T200

System PROM revisions:
:wall:

That is your firmware version.

My T2000 recently updated is:-

OBP 4.30.4.d
Hypervisor 1.7.3.c
POST 4.30.4.b

Why are you asking?

I have to upgrade the the firmware in order to patch it with latest kernel patch. The requirnment is that FIRMWARE should be at least 6.4.6.

For other systems, when I do showhost or do prtdiag, I am getting an output as :

Sun-Fire-T2000 System Firmware 6.7.12  2011/07/06 20:03

So, was wondering what is the version for this system as it is not visible in showhost neither in prtdiag?

My T2000 gives firmware info in response to the showhost command on the system controller (SC> prompt).

What does your system say when you enter "showhost" at the SC> prompt?
