I'm not sure how to do it with any ipmi-based commands, but "dmidecode -s baseboard-serial-number" should return that information from the OS. On my Dell systems, it returns two rows of information. The first contains the system's service tag, the board's serial number (ipmi-fru's first entry), and the slot number separated by period characters. The second line is the chassis' serial number and the slot number, similarly separated. We don't have asset tags set, so those may show up in there to if you use them. Information can be pulled from HP systems in a similar fashion with "dmidecode -t 204 |grep 'Server Bay'" or just "dmidecode |grep 'Server Bay'"

This information is also available remotely via SNMP to the iDRAC: "snmpget -t 1 -r 1 -c public -v2c -O qve $yourhost-idrac DELL-RAC-MIB::drsProductSystemSlot.0". You'll have to download the MIBs from

By the way, we also do inventory tracking in a similar fashion to what you're moving towards. It works quite nicely when everything is set up.

I've looked before at doing this via IPMI but also came up short.

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

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.
