Unable to get info about single DIMM

[alexyack]

I am using ipmitool version 1.8.18-8 on Ubuntu 20.04

When issuing command to list all FRUs - info is read successfully:

$ ipmitool -I lanplus -H x.x.x.x -U *** -P *** -v fru
...

But when I issue command to get info only by this DIMM I get this error:

$ ipmitool -I lanplus -H x.x.x.x -U *** -P *** fru print 110

 Unknown FRU header version 0x23

Is it an error or my misprint?

Have you tried it with the latest code from this repository?

[alexyack]

Yes, the same result.

ipmitool version 1.8.18.206.g50d8c36

Then this is probably a bug. The FRU code is unfortunately very dirty and needs heavy refactoring.
