Hello,

tried to convert HANA 2.0 SPS00 from single-container system to a multi-container system with hdblcm command-line, but during convertion I got a nameserver error and the converting failed.

Using HANA 2.0 SPS00 (Rev 2.00.002.00) on SLES 12 SP1

Can anyone help please?

Now system doesn't even start.

HDB start --> FAIL: process hdbdaemon HDB Daemon not running

Starting nameserver manually also doesn't work

Please see log of convertion process

Nobody an idea? Any hints would be very helpful. I still don't know why the nameserver is not responding.

Best regards,

Andrej

Hi Sadiq,

after opening a ticket, SAP told me that this is a known bug which occurs when a HANA system was initially installed as HANA 1 and upgraded to HANA 2. The error dies not occur when upgrading to SPS01, which includes multi-tenant conversion.

Regards, Andrej
