Looking for psrinfo-like command for Memory Modules
I've been looking for, but unable to find, a command/utility that functions kind of like psrinfo but for memory modules. I have Solaris 8 and Solaris 10 boxes. The output of prtdiag in Solaris 8 does not provide the status info for the CPUs and Memory Modules like it does in Solaris 10. Maybe Solaris 8 will show something that's faulty in the Fru Operational Status section but I don't know. Perhaps it's just been luck that the Solaris 8 boxes are not experiencing problems. But the Solaris 10 boxes have been having both CPU and Memory failures.

Code:
 
Host_Solaris8:> /usr/platform/`uname -i`/sbin/prtdiag | head -10
System Configuration: Sun Microsystems  sun4u Netra 240
System clock frequency: 160 MHZ
Memory size: 4GB
==================================== CPUs ====================================
                      E$          CPU     CPU       Temperature         Fan
       CPU  Freq      Size        Impl.   Mask     Die    Ambient   Speed   Unit
       ---  --------  ----------  ------  ----  --------  --------  -----   ----
     MB/P0  1280 MHz  1MB         US-IIIi  2.4       -        -
     MB/P1  1280 MHz  1MB         US-IIIi  2.4       -        -
 
 
Host_Solaris10:> prtdiag | head -10
System Configuration: Sun Microsystems  sun4u Netra 240
System clock frequency: 167 MHZ
Memory size: 4GB
==================================== CPUs ====================================
               E$          CPU                    CPU
CPU  Freq      Size        Implementation         Mask    Status      Location
---  --------  ----------  ---------------------  -----   ------      --------
0    1503 MHz  1MB         SUNW,UltraSPARC-IIIi    3.4    faulted     MB/P0
1    1503 MHz  1MB         SUNW,UltraSPARC-IIIi    3.4    on-line     MB/P1

When I first encountered a failed CPU, I then found psrinfo which gives consistent output whether on Solaris 8 or 10.

Code:
Host:> psrinfo
0       faulted   since 12/16/2008 12:45:49
1       on-line   since 12/04/2008 02:14:35

Since then, I've encounter failed memory modules on a Solaris 10 box. But, as with the CPUs, prtdiag in Solaris 8 does not have a status field for the memory.

Code:
 
Host_Solaris8:> /usr/platform/`uname -i`/sbin/prtdiag | tail -18 | head -6
Memory Module Groups:
--------------------------------------------------
ControllerID   GroupID  Labels
--------------------------------------------------
1              0        MB/P1/B0/D0,MB/P1/B0/D1
1              1        MB/P1/B1/D0,MB/P1/B1/D1
 
 
Host_Solaris10:> prtdiag | tail -8
Memory Module Groups:
--------------------------------------------------
ControllerID   GroupID  Labels         Status
--------------------------------------------------
0              0        MB/P0/B0/D0
0              0        MB/P0/B0/D1
1              0        MB/P1/B0/D0    failed
1              0        MB/P1/B0/D1    failed


If anyone knows of a consistent way, across Solaris8 and Solaris 10, to identify failed memory modules, I would love to hear it.

prtdiag

prtdiag(1M)                                                                                                                            prtdiag(1M)

NAME

       prtdiag - display system diagnostic information

SYNOPSIS

       /usr/sbin/prtdiag [-v] [-l]

       prtdiag displays system configuration and diagnostic information on sun4u and sun4v systems.

       The diagnostic information lists any failed field replaceable units (FRUs) in the system.

       The interface, output, and location in the directory hierarchy for prtdiag are uncommitted and subject to change in future releases.

       prtdiag  does  not  display  diagnostic  information  and  environmental  status  when executed on the Sun Enterprise 10000 server. See the
       /var/opt/SUNWssp/adm/${SUNW_HOSTNAME}/messages file on the system service processor (SSP) to obtain such information for this server.

       The following options are supported:

       -l       Log output. If failures or errors exist in the system, output this information to syslogd(1M) only.

       -v       Verbose mode. Displays the time of the most recent AC Power failure, and the most recent hardware fatal error information, and (if
                applicable) environmental status. The hardware fatal error information is useful to repair and manufacturing for detailed diagnos-
                tics of FRUs.

       The following exit values are returned:

       0        No failures or errors are detected in the system.

       1        Failures or errors are detected in the system.

       2        An internal prtdiag error occurred, for example, out of memory.

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE         |      ATTRIBUTE VALUE        |
       +-----------------------------+-----------------------------+
       |Availability                 |SUNWkvm                      |
       +-----------------------------+-----------------------------+
       |Interface Stability          |Unstable*                    |
       +-----------------------------+-----------------------------+

       *The output is unstable.

       modinfo(1M), prtconf(1M), psrinfo(1M), sysdef(1M), syslogd(1M), attributes(5), openprom(7D)

NOTES

       Not all diagnostic and system information is available on every Solaris platforn, and therefore cannot be displayed by  prtdiag.  On  those
       platforms, further information can be obtained from the System Controller.

                                                                    29 Aug 2005                                                        prtdiag(1M)
