Oracle 11 installation problem on SLES 11 SP2

Before starting an installation of Oracle 11 with the grid infrastructure on SLES11 SP2 it's highly recommended to read the Oracle note with the title "OHASD fails to start on SuSE 11 SP2 on IBM: Linux on System z [ID 1476511.1]".
OHASD is the Oracle High Availability Service Daemon. So if this doesn't start on zLinux SLES 11 SP2 then consult the Oracle note above on http://support.oracle.com/.
