I am not able to open SAP GUI in HANA Studio and is showing an error "hostname itrs55" unknown. In our landscape (DEV, QA, PROD) --> DEV and QA are on the same physical HANA machine. I tried to workthrough the details provided in the NOTE 2103008 and modified the 'hosts' file with three lines. The ip address, etc. for DEV and QA have been written the same. Now, for QA and PROD, I am able to open the SAP GUI but not for DEV.
Any ideas what is to be done?
