Power capping 41
After established and saved in the EEPROM, the baseline data can be examined at any time using the SHOW
POWER BASELINE command. For example:
> show power baseline

If a SL-APM has baseline data in its EEPROM and it is reset, SL-APM will re-read that baseline data back into
memory as it boots back up and after the subsequent device discovery compares the baseline data in the
EEPROM to the actual rack contents to ensure that they did not change while it was offline or that it was not
relocated to another rack. The SL-APM validates the following things from saved baseline data in these
instances:
• The chassis listed in the baseline is present.
• The chassis has the same populated server slots.
• If a power cap had been set, that this is the power cap currently set on the chassis.
If any of these do not match up after a reset, then the SL-APM logs an error to the log, indicating the mismatch
in the baseline data and the baseline data will be invalidated. It will not, however, be erased from the
EEPROM to provide you the chance to re-install any chassis or servers that invalidated the baseline data.
To remove baseline data from the EEPROM, use the SET POWER BASELINE NONE command. After this
command is used, the only way to re-establish a power baseline is to use the SET POWER BASELINE
command.
If a power cap is currently in place, the SET POWER BASELINE NONE command cannot be used. The power
cap must first be removed (SET POWER CAP NONE) then the baseline can be removed.
If a power cap is currently in place and a SET POWER BASELINE command is issued, then any current
power caps will be removed in the calibration. New power caps can be established following the calibration
process, assuming the new baseline data is saved to the EEPROM.
The following text is an example output when an advanced license is installed on all chassis:
> set power baseline
Before running a baseline calibration - ensure that
your configuration has all machines turned on and are
running processes that are typical of the type of workload
you expect them to run in a production environment.
This process will briefly impact the performance of the
servers that are being baseline calibrated as well as
temporarily speed up the fans.
Are you sure you wish to set a new power baseline for this system? (Y/N/Q)
