About this task
For Troubleshooting reasons it is helpful to read the logs of a specific scanner

In some cases the Topology or Performance Scanner may fail due to a communication problem between HMC and VIOS or an error in VIOS. The error message in the Scan Log is not that informative to quickly identify the originator and fix the error. The log provides the UUID of the Managed System, which must then be resolved to the name of the Managed System.
Since BVQ Release 2023.H1. the output in log files has been extended by the readable names of Managed Systems, Logical Partitions and also the name of the queried HMC.
Applies to
BVQ Version: any
Procedure
A simple way to resolve this UUID to the readable name of the Managed System can be implemented via a direct REST query of the HMC via a browser.
Insert UUID into a simple URL pattern to query the HMC for this specific Managed System:
https://hmcXXX.de:12443/rest/api/pcm/ManagedSystem/38XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX77/preferences
Alternatively, all Managed Systems of HMC can be queried and then searched for the corresponding entry:
https://hmc.XXX.de:12443/rest/api/pcm/preferences
HMC can be the IP address of the HMC or the host name of the HMC.
The generated result file contains one paragraph per Managed System, which then also contains the name of the Managed System.
With the now uniquely determined name of the Managed System, the recommended actions can then be executed on the VIOS of the affected system.
