PowerPath Management Appliance (PPMA): rpowermt commands stopped working post upgrade of PPMA 3.2 to 3.4 P01
Summary: PowerPath Management Appliance (PPMA): rpowermt commands stopped working post upgrade of PPMA 3.2 to 3.4 P01.
Symptoms
Running rpowermt commands kept on returning the following error for all the PowerPath/VE hosts:
ERROR: ELMC720: Unable to fetch token for communication. Verify the PPMA details provided and ensure that PPMA instance is running.
rpowermt commands were working before the upgrade.
Cause
In this specific case, the user used the same password for "ppadmin" user as that of "root" user during the upgrade. And while attempted to run any rpowermt commands, it kept on erroring out with the above error ELMC720.
The root cause was not setting up the same password as that of "root" user. But something else which seemed to be environmental in the User's setup and could not be reproduced in our lab beds even after multiple trials.
Resolution
rpowermt commands could be successfully run post changing the "ppadmin" password.
