Hello,
The log messages you are seeing indicate that your HP 560 is running a Comware image at the moment. This is the case because this AP was previously controlled by an HPE Unified Wired WLAN controller like HP 830, 850, 870, 10500 Wlan module etc. The Comware image doesnt support AP autonomous mode, only controlled mode and in this case the AP firmware is updated automatically by the controller
If your goal is to run the AP in autonomouls mode and be able to update and manage it separately you have to go to the download page of the AP and select release 6.5.0.0.
https://h10145.www1.hpe.com/downloads/SoftwareReleases.aspx?ProductNumber=J9846A
Download from this page the zip archive V6.5.0.0-HP560-B19493.zip.
Here you can find a couple of files. Please first read the pdf document called HP_UnifiedToMSM(TFTP)_instructions.pdf If I understand your requirements correctly in Step 2 you need to follow Load Method 2 Using TFTP. because you dont have an MSM controller. Please note that for this instruction you need to use the V6.5.0.0-HP560-B19493.cim.startup file not the V6.5.0.0-HP560-MSM410-MSM430-MSM460-MSM466-MSM466R-B19493.cim file.
After finishing the procedure you should be able to switch the AP to autonomous mode using the WebUI. In the webUI you can update to any version you want if you are entitled to run this version.
Let me know if you have any questions or something is not working as expected.
