Doc Text:
Prior to this update, SMBIOS implementations newer than version 2.7 were not fully supported by the dmidecode tool in Red Hat Enterprise Linux 6. As a consequence, dmidecode was not able to automate builds and deployments on certain hardware. To fix this bug, dmidecode has been updated and now supports version 2.8 SMBIOS.

Description chris procter 2014-01-03 06:41:17 EST 
Description of problem:

With the latest bios version (2013.11.14) on HP BL460c Gen8 blade servers dmidecode reports:
# SMBIOS implementations newer than version 2.7 are not
# fully supported by this version of dmidecode

at the start of all output. Otherwise the output looks to be correct. This additional warning message is enough to break scripts expecting a single line of output.


Version-Release number of selected component (if applicable):
dmidecode-2.11-2.el6_1.x86_64  


How reproducible:
Every time

Steps to Reproduce:
1. run "dmidecode -s system-product-name" or similar
2.
3.

Actual results:
# SMBIOS implementations newer than version 2.7 are not
# fully supported by this version of dmidecode
ProLiant BL460c Gen8

Expected results:
ProLiant BL460c Gen8

Additional info:
The full dmidecode ouput includes the line "SMBIOS 2.8 present".

The 2013.09.18 version of the bios does not produce this message.
Comment 2 chris procter 2014-01-03 07:16:19 EST 
This has also been confirmed on DL360p Gen8 and DL380p Gen8 servers with the 2013.11.14 bios
Comment 3 chris procter 2014-01-03 08:41:28 EST 
This has also been reported to me on RHEL5 with dmidecode-2.11-1.el5.x86_64
Comment 4 Anton Arapov 2014-01-03 09:03:11 EST 
Chris, could you attach the binary dump of this system to bugzilla?

see dmidecode's --dump-bin option.

thanks!
Comment 6 chris procter 2014-01-06 05:56:33 EST 
We have tried compiling the source available from  http://download.savannah.gnu.org/releases/dmidecode/dmidecode-2.12.tar.gz
Which gives us the same message (but reporting a different dmidecode version):
# dmidecode 2.12
SMBIOS 2.8 present.
# SMBIOS implementations newer than version 2.7 are not
# fully supported by this version of dmidecode.


We have also compiled the cvs version of the source and that works correctly:

# dmidecode 2.12
SMBIOS 2.8 present.
192 structures occupying 6294 bytes
[etc etc]


(both compilations on the same RHEL6.4 DL380p)

Is it posible to get the CVS version into RHEL 5&6 as an errata?
Comment 7 Anton Arapov 2014-01-06 06:22:02 EST 
If there is a demand. Let's try, will see what PMs say. :) 

You may want to clone this bug for rhel5 too.
Comment 12 Dan Beimborn 2014-01-23 09:43:55 EST 
This is impacting us as well, dmidecode scripts are commonly used to read the vendor serial number of hardware for automated support tools, or in our cases as a fingerprint/primary key for the server

FYI, this change went into RHEL5 (bug 1048920).
