ECC 6.0 upgrade to EHP4 via EHPI - Problem

I'm upgrading an ECC 6 system to EHP 4.

In the extraction process I get the a strange error message:

Error: unknown hostname "<hostname>"

The message server of your SAP system is not running,

or the hostnames known by the message server are wrong.

I've checked. The message server is running and the hostname is known in my host file and in the server's hostfile.

Any idea's to what this is causing?

    What step are you in? Is it looking for your switch instance? You should have two instances running. Your original instance and your switch instance. The switch instance is the one that is upgraded and then switched during the downtime. I had a situation where that was not available after I shutdown and I had to manually start that instance.

    Hi,

    Please help on this. I am getting the same error.

    ERROR: unknown hostname "<hostname>"

    The message server of your SAP system is not running,

    or the hostnames known by the message server are wrong.

    We have HA installation on Solaris.

    Regards

      Problem solved: replaced ALL entries regarding hostname or sapsystemname or whatever in HOSTS file and PROFILES to lowercase.
