EHP5 post upgrade steps for MSCS

Hi Experts,

while upgrading our ERP 6.0 system to EHP5 running on windows MSCS Cluster environment with sql server 2003.

We had followed the procedure mentioned in guide for updating EHp5 in cluster.

1. EHP5 upgrade was run on the first mscs node and finished.

2.Cluster resource dll files updated as per note 1050343.

3.Brought all SAP,SQL and cluster resource group online on node1.

4.As part of post upgrade we started with BSI2010 installation master

dvd and used option EHP5 for SAP ERP6.0 -s/w lifecycle options-Post

upgrade-High availablity system-First MSCS node.

5. We uninstalled the existing ERS running on 700 version to install

new one with 720 but this does not help to run the system in cluster.

Problem is once the ehp5 upgrade completed while performng the post upgrade tasks using the BS2010 inst master cd.

we selected the below options

option EHP5 for SAP ERP6.0 -s/w lifecycle options-Post

upgrade-High availablity system-First MSCS node.

while excuting the above we are unable to proceed as it throws error as

"Cannot find an ABAP CI SAP instance appropriate for clustering"

solution check yourinput data..

Could you please confirm is it really neccesary to run first mscs node and additional node prepartions and then intsall ERS 7 update DI instances on all node...

We have followed SAP note 941092 but unable to resolve...

Thanks in advace..kindly help.

Regards

rasool

    Hi,

    You need to install ERS only. You can check SAP note 1012486 in section post upgrade activities.

    Thanks

      Hi Sunny/Rasool,

      Nice to see the steps for ehp5 upgrade on mscs . we are planning to do the ehp5 upgrade of our prdocution server which is on microsoft cluster environment.I read the steps provided by rasool and the solution to the query by sunny.

      our platform is windows 2003 64 bit , databasbe mssql 2005 , microsoft cluster enviroment on two seperate nodes. Node 1- database . node 2 - CI.

      Could you please let me know whether , we need to perform extra activities otherthan the steps mentioined by rasool. As i am not good in cluster area , appreciate if you would provide the steps in details and the issue which can occur during the upgrade.

      Can we use (ehp5 upgrade master cd instead of ehp5 installation mater cd for installing ER).

      please guide to go ahead the upgrade process smoothly...

      regards
