Hello,

You have probably 400MHZ/8MB CPU's installed. For Solaris 2.5.1 & 2.6 you
need to do following this procedure to limit the ecache size to 4MB. Later
on after you installed the right patch you cab re-enable it.

Note that there are two sets of instructions below. The first set
describes the required software prerequisites for installing the
400MHz/8MB CPUs on an existing Enterprise 3X00-6X00 server that is
running Solaris 2.5.1, Solaris 2.6 or Solaris 7. The second set describes
the procedure for installing Solaris 2.5.1 or Solaris 2.6 on a new
system that is configured with 400MHz/8MB CPUs.

Instruction Set 1.
------------------

    Installing the 400-MHz 8-Mbyte module into an existing E3x00-6x00
    system running Solaris 2.5.1, Solaris 2.6 or Solaris 7:

        1. check the firmware revision by typing /usr/sbin/prtconf -V at
        the UNIX prompt. Upgrade to flash PROM version 3.2.21
        (or compatible versions) if the PROM version displayed
        indicates an earlier revision.
        
        2. Through your browser, go to "http://sunsolve.sun.com"
        
                if you do not have internet access, contact your
                Sun service representative for instructions.
                
        3. Select the following links in order:
        
                a. Patches

                b. Recommended and Security Patches
                        Select "Agree" at the bottom of the Software
                        License Agreement
                
        4. Select the required Solaris operating environment
           patches as follows (not required for Solaris 7):
   
                a. Select your version of Solaris operating environment
                version from the table titled, "Recommended and Security
                Patches for Solaris".
   
                b. Select the required patch for your version of the
                Solaris operating environment using the following table.
   
    --------------------------------------------------------------------
    Select your Solaris operating Choose this patch or
    environment version compatible versions
    --------------------------------------------------------------------
    Solaris 2.5.1 #103640-27 *
    Solaris 2.6 #105181-14
    Solaris 7 none required
    ---------------------------------------------------------------------

                c. See the README file for each patch for further
                instructions
                
        5. For flash PROM updates:
   
                Scroll to "Recommended and Security Patches for
                Unbundled Products" and select the "Hardware" category,
                then select patch #103346-xx (flash PROM update version
                3.2.21 or compatible versions).
                

        6. Halt the operating system, and then turn off the system
                power.
                
        7. Remove and replace the CPU modules (and clockboard, if
                necessary).
                
        8. Power on the system.
        
        
* Note: There is another patch which is not specific to the 400MHz/8MB
CPU, but is still required for Solaris 2.5.1: patch #104595-06
See the README file for this patch for further instructions
        
===========================================================================

Instruction Set 2.
-------------------
                
        Installing Solaris 2.5.1 or Solaris 2.6 on a brand new system
        with 400-MHz 8-Mbyte CPU modules configured. (These
        instructions are not required for Solaris 7 operating
        environment):

        Note - This procedure must be performed in the order
        specified.
        
        1. Power on the system and at the ok prompt,
                type "limit-ecache-size".

                This will temporarily limit the system to using
                only 4MB of Ecache.
        
        2. Install Solaris 2.5.1 or Solaris 2.6 operating environment
                from network server or from CD-ROM, choosing to halt the
                system after installation and before booting Solaris.
        
        3. At the ok prompt, type "limit-ecache-size".
        
        4. Boot up the newly installed operating environment
        
        5. Through your browser, go to "http://sunsolve.sun.com"
        
                if you do not have internet access, contact your
                Sun service representative for instructions.
        
        6. Select the following links in order:
        
                a. Patches
                
                b. Recommended and Security Patches
                        Select "Agree" at the bottom of the Software
                        License Agreement
                
        7. Select the required Solaris operating environment
          patches as follows (not required for Solaris 7):
   
                a. Select your version of Solaris operating environment
                version from the table titled, "Recommended and Security
                Patches for Solaris".
   
                b. Select the required patch for your version of the
                Solaris operating environment using the following table.
   
   --------------------------------------------------------------------
    Select your Solaris operating Choose this patch or
    environment version compatible versions
   --------------------------------------------------------------------
    Solaris 2.5.1 #103640-27 *
    Solaris 2.6 #105181-14
    Solaris 7 none required
   ---------------------------------------------------------------------

                c. See the README file for each patch for further
                instructions
        
        8. Reboot the system.

* Note: There is another patch which is not specific to the 400MHz/8MB
CPU, but is still required for Solaris 2.5.1: patch #104595-06
See the README file for this patch for further instructions

99% of the time this is a blown CPU.. call Sun Service to get them to come
out and replace it. We've had the same problem hear a couple of times,
and both times a CPU swap-out fixed it.

I think that's an issue with the Hardware version of the cdrom you're
booting off of. Try a cd with a newer hardware version like 11/98 or and
99 version.
