I am not sure how much you can decode the store.logs file. You can try unzip the file and open with Notepad++ then take a look for all drives serial number which are currently present in the system. You can also get the drive serial number from SMU or GUI or CLI as well. Take each drive serial number and search. In results window look for medium error or hard error of the drive. To be more specific look for sense key. To understand more about sense you can refer the below guide,
https://en.wikipedia.org/wiki/Key_Code_Qualifier
You can also log a case with HPE support and review the logs to find drive errors because we have Internal tool to decode the logs.
We can also look for vdisk level error as well which may get captured as part of scrub process.
Hope this helps!
