Subject: [Openhpi-devel] Device SDR Repository --> HPI ResourceTag
Good afternoon,
I'm trying to get an OpenHPI implementation on a bladed ATCA chassis
working. (I still have 2.0.4, but I haven't seen better results when
experimenting with 2.10.1.) I'd like to be able to put the string for our
internal AMC card ID in the ResourceTag element of the SaHpiRptEntryT
structure.
At the IPMI level, this string is located in the FRU Device Locator Record
SDR corresponding to the AMC card in the SDR repositories maintained both by
the shelf and by the Intel blade (MPCBL0040). (See Table 43-7, FRU Device
Locator Record on page 525 of this document:
http://www.intel.com/design/servers/ipmi/pdf/IPMIv2_0_rev1_0_E3_markup.pdf.)
The problem is, I seem to 'lose' this string by the time I get to the
high-level RPT tables that my application can read. It shows up as the 'Id'
in the 'ipmish' output, as shown:
Entity
Name: d(r0.148.193.6)
Type: fru
Present: true
Presence sensor always there: false
Hot swappable: true
Supports managed hot swap: true
Parents
Name: d(r0.148.160.0)
Id: AH0305-4
Entity ID String: invalid
>From looking at the 'ipmi' plugin code (I have had better luck getting this
working on my system than I have 'ipmidirect'), it appears the the 'Entity
ID String' is what's being read into the ResourceTag field. This string
seems to be directly related to the numerical 'entity ID', in this case 193
(an OEM value, I understand). Indeed the 'invalid' marker is what shows up
in the 'hpitree' output.
* If I got 'ipmidirect' to work, would it behave differently?
[Pierre] Have you tried ipmidirect with 2.10.1? If it works, it should give
you what you are looking for.
* Is there any way to access this string using the 'ipmi' plugin, or
should I focus on another method of identifying the board at the HPI level,
such as the entity path, or the Manufacturer/Product ID combination in
SaHpiResourceInfoT?
Thanks a lot, and have a great New Year!
Jason
