Hi Deerendra,
please check SAP note 2078425 - Troubleshooting note for SAP HANA platform lifecycle management tool hdblcm
In my case I had to reconfigure the SAP Host Agent as described in the note:
To update the integration of hdblcm on the SAP HANA host, run the following command:
<sapmnt>/<SID>/hdblcm/hdblcm --action=update_host
PLEASE BE AWARE that the HANA database might stop aumatically when running the command!
Restart SAP Host Agent
/usr/sap/hostctrl/exe/saphostexec -restart
Afterwards I was able to start the SAP HANA Platform Lifecycle Management within the HANA studio.
Regards
André
