Changing hostname of a SAP system on Linux

[former_member389036]

Hi Gurus,

In our project there is a requirement to change both hostname and sid of a system. In SWPM I see an option to rename system which actually does the job. But when I run it, I get an error message "\\<newhostname\sapmnt\<newsid>" not accessible. Now my question is, do we need to rename the host first before we run this option? is there any documentation available for the correct procedure to run the option? Pl help...

Regards,

Hi Suman,

please check the Rename guide, it says: "Before you start the system rename, mount the file system, which you have unmounted in the previous step, under the new <SAPSID>." I guess that's the step that's missing in your case. Guides are here.

You can do it all in one step.

Can you check if the share is accessible from File Explorer?

\\<newhostname\sapmnt\

Hi Bartosz,

No, its not accessible. If the hostname is not changed then how can it access the shared location with new hostname? Do I need to put an entry in hosts file and try?

Sorry, I didn't understand you correctly.

Before running system rename, you need to change the hostname of your server.
