[PATCH] V3 Introduce IPMI BMC Info
Deb McLemore
debmc at linux.vnet.ibm.com
Thu May 5 14:35:21 UTC 2016
V3 changes the IPMI presence check to a simple stat.
This feature adds the foundation to perform an IPMI BMC Info
check that will determine if a Host is capable of
IPMI messaging and if so will perform a basic IPMI message
exchange to determine the version of IPMI running
on the hardware. In the future the IPMI infrastructure
can be used to further interrogate the FRU Inventory and other
Sensors to help correlate data and surface any
discrepancies on inventory or hardware characteristics.
