    HI Daniel,

    Please check the KBA :

    2168178 - Error during phase MAIN_SHDRUN/SUBMOD_FDC_PREP/RUN_FDC4UPG_PREPROC: A2EESCRR 136 Cannot read server list

    This seems issue with hostname.

    Best Regards,

      Issue resolved after maintaining hostname in shadow instance profiles and /etc/hosts file same as the one in SM51 (hostname). Else maintain SAPLOCALHOST parameter value in shadow instance to the one same as SM51 and /etc/hosts.

    I had the same Problem few minutes ago.

    I could solve it by:

    - adding the logical hostname to /etc/hosts upper case

    - verifying SAPLOCALHOST and SAPLOCALHOSTFULL upper case at instance profile of shadow instance

    - restarting shadow instance with ./SAPup stopshd, sapcontrol -nr <Instance number of shadow instance> -function RestartService and ./SAPup startshd

    After this the hostname is shown in upper case in TA SM51.

    Best Regards

    Checked following entries:

    SAPLOCALHOST in Windows System Properties

    Shadow Instance Profile --- RZ10 SAPLOCAL HOST Entry

    Shadow Instance --- SM51 Hostname entry


    Note: All 3 Parameters have to match up word for word and upper/lower case entries.
