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.	Story Points:	---

Description chris procter 2014-01-03 11:41:17 UTC

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.

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 13:41:28 UTC

This has also been reported to me on RHEL5 with dmidecode-2.11-1.el5.x86_64

Comment 4 Anton Arapov 2014-01-03 14:03:11 UTC

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 10:56:33 UTC

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 11:22:02 UTC

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 14:43:55 UTC

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

Comment 15 Anton Arapov 2014-01-29 13:08:39 UTC

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