How To

Summary

Use new HMC API features to verify the state of the PowerSupplies and FANs of managed systems

Objective

Display PowerSupply and FAN status

Background: The HMC will log an event if a PowerSupply/FAN has a fault, but will not currently CallHome if there are still enough units to maintain the required minimum serviceable number.

Using this utility can display the status of all the PowerSupplies and Fans and provides visibility.

Environment

Power 8, 9 and 10 using IBM HMC

HMC and Server Versions:

HMC - 8.6 SP2 with PTF MH01716

Server firmware - 860_103

The attached python script has been tested on a RHEL 8.6 System (RHEL on Power)

The python environment needs lxml and request packages to be installed

Tested with Python 3.6, 3.8 and 3.11 with appropriate requests and python-<ver>-lxml packages installed

Steps

Copy the hmc_hwi.py script to a location of choice

Edit the top of the script to point to your Python3 location eg #!/usr/bin/python3.6

chmod the script to be executable eg chmod +x hmc_hwi.py

To run:

hmc_hwi.py : -i | --hmc hmc name (or comma seperated list)
-u | --user hmc user
-p | --password hmc password (if left blank will prompt)
-s | --sysnames system name (or comma seperated list)

-i | --hmc can be single hmc or a comma separated list of hmc FQDN or IP addresses
-s | --sysnames can be a single system name or comma separated list of systems to print status for
(the name only has to be a unique part of the Managed System Name, not the entire string)

rhel8host: /usr/local/scripts/hmc_hwi.py -i mylabhmc.local -u myuser -s myp10 -p Password: SystemName:myp10test

Additional Information

The script does not sort the results - they are processed as per how the HMC API call sends them.

Future enhancements may include:
- sort on the output based on Managed System Name

- Flags to display units in Error State only or 1 line Summary

- Dump the entire received HW Inventory per Managed System to a file/human readable for cross checking of HW profiles

- The script name should appear below this as hmc_hwi.py__0.txt please do check back for new versions
