Strange.. if the system doesn't support power monitoring, the plugin
shouldn't complain about it. Are you using check_openmanage via SNMP or
locally?

(I'm guessing SNMP, and if so there are obvious inconsistencies
between what OMSA displays through omreport and what is available via
SNMP.)

Did power monitoring work at all before upgrading OMSA?

I forgot one other possible cause: old BIOS and/or firmware. Newer
versions of OMSA often need relatively up-to-date BIOS and firmware
versions to function normally. You should upgrade all BIOS and firmware
on the server.
