This document describing how to check and update Update Access Key (UAK) automatically before it gets expired.
Starting from power 8 machine and later, Update Access Key (UAK) is checked before system firmware updates are applied to the system. If UAK is expired, firmware updates cannot be processed.
As a result, UAK needs to be checked periodically, doing that for multiple systems would be a headache, instead, UAK update can be done automatically.
- From Hardware Management Console (HMC) home page, select Serviceability then select Service Management.
- Next page, select Transmit Service Information.
- Then, scroll down to Update Access Key Information, mark the check box, and select update interval (default is 7 days).
- Once UAK got updated, HSCE2123 entry is logged in to HMC log file indicates that "chcod" command was executed successfully.
