I tried iterating from 0xC0 through 0xCF on some Dell M610s and didn't find the slot number. I compared the results of several that were in the same chassis so that most of the information would be the same. I saw no differences that seemed to indicate the slot number. The only differences at all that I saw from blades in the same chassis were at 0xC3 and 0xC5 (expected). We don't have asset tags set or I would expect to see differences in 0xC4.

Hi Chris,

I might be misunderstanding your question, but it seems you want to
figure out what type of board is inside each slot?  I assume the
ipmi-oem Dell command 'get-system-info' isn't enough b/c you only get
the board name and not the slot number?

I don't know of any OEM commands for this, so the first thing is I'd bug
Dell, b/c someone there might be able to provide it (you will have to
fight them to get to the right people, the first line support will
likely have no idea).  If you get something from them, please let the
list know and we can put it in ipmi-oem.

Depending on your willingness to try and reverse engineer something,
there might be a way to determine it.  The following is an ipmi-raw that
should implement the same thing as "ipmi-oem dell get-system-info

/usr/sbin/ipmi-raw 0 6 59 0 0xC4 0 0

In ipmi-oem here's a comment on the parameter numbers:

    * guid parameter = 0xC3
    * asset-tag parameter = 0xC4
    * service-tag parameter = 0xC5
    * chassis-service-tag parameter = 0xC6
    * chassis-related-service-tag parameter = 0xC7
    * board-revision parameter = 0xC8

This is what we know of or have been told.  It wouldn't be hard to
imagine that 0xC9, 0xCA ,0xCB might return your slot number.

I've just learned about the wonders of IPMI this past month and have re-written 
our inventory system from scratch to take advantage of the data the FreeIPMI 
suite of tools provides easy access to. Right now the only drawback is that I 
have to run a secondary script at each co-location to access each of our Dell 
M1000e chassis, running proprietary racadm command over SSH to correlate which 
10g/11g PowerEdge blades are running in the various slots. I've been digging 
through the documentation in hopes of finding either a oem command that I can 
run or even a ipmi-raw command that can be passed to each blade to pull this 
data, but so far I've come up short.

Has anyone on this list been able to identify a method to capture this 
particular information? Dell's OMSA utility also provides the slot information 
as seen in the output below.

Thanks in advance for the time guys.
