This update is not applicable for HVM domU HVM domU (Doc ID 2725110.1)

Last updated on MARCH 16, 2021

Applies to:

Oracle Exadata Storage Server Software - Version 19.3.12.0.0 and later
Information in this document applies to any platform.

Symptoms

exadata.computenode.post step fails while updating VM on virtualizes Exadata (X7-2).

Symptoms:
patchmgr starts exadata.computenode.post step and waits for this step to complete within the defined timeout. But this step does not run properly since exadata.computenode.post.log show message "This update is not applicable for HVM domU HVM domU" and quits without doing anything at all. After the timeout expires, patchmgr rolls back to former image backup.

Pre Analysis:
The problem seems to be that the scripts (obviously /opt/oracle.cellos/image_functions) depends on the system-product-name gathered from dmidecode and expect a value of "HVM domU". But the message shows this value doubled "HVM domU HVM domU".

exadata.computenode.post.trc this this output with the wrong value too:
[1604011033][2020-10-29 23:52:39 +0100][TRACE][/opt/oracle.cellos/image_functions - 1074][source][] The system model is: HVM domU HVM domU

The problem was seen only on one VM other VM succeeded without problem.
