Failover cluster installation

[Former Member]

Hello,

I would like to install SAP ECC6 EhP4 from System Copy (backup/restore) in Windows failover cluster environnement with two nodes.

So, I have installed MSSQL Server 2008R2 SP2 in cluster mode (using virtual host : FRSERVERSQL).

Now, I have to install SAP ECC. (A virtual host has been created : FRSERVERSAP)

I have created manually SAP SID service on "Failover cluster manager" windows menu.

Inside this service, I have created :

- IP resource

- Shared folder (sapmnt : E:\usr\sap)

- Disque resource (E:)

I have created saploc shared folder (c:\usr\sap)

Following install guide and some SCN threads, I have doubt with the way to install SAP in Windows failover cluster environnement.

I found this way on SCN :

1. Central services instance for ABAP installation.

  Use the command line sapinst.exe SAPINST_USE_HOSTNAME=FRSERVERSAP

  Note - during the installation time all the cluster resource should be in Node 1

2 First MSCS node installation => on Node I? Do I need to use SAPINST_USE_HOSTNAME=FRSERVERSAP ???

3 Database Instance Installation => Do I need to use SAPINST_USE_HOSTNAME? If yes, do I use FRSERVERSQL???

4 Additional or Second MSCS node installation => on Node II? with SAPINST_USE_HOSTNAME?

5 Enqueue replication server installation for ABAP in Node I

6 Enqueue replication server installation for ABAP in Node II

7 Central Instance Installation in Node I

8 Dialog Instance Installation in Node II

9 Post processing steps after system copy

One more question.

After installation is OK, If I have to refreh this environnement (with homogenous sytem copy - backup/restore),

which option should I have to use after restore? Only Database instance installation or all options described above?

Thanks for your help

Hi,

after doing my sourc e system export, what are the steps to refresh (homogeneous system copy with backup/restore) my High Avaibility Cluster target system ?

Do I need to proceed with all steps as when I have installed it or only Database Instance (after doing database restoration)?

Hi

After the source system exported you have stat the import in target system

1. Restore the Latest DB backup in Target cluster system
2. Central services instance for ABAP installation.
3. Central services instance for JAVA installation.
4. First MSCS node installation
5. Database Instance Installation using backup restore method
6. Additional MSCS node installation
7. Enqueue replication server installation for ABAP in Node I
8. Enqueue replication server installation for JAVA in Node I
9. Enqueue replication server installation for ABAP in Node II
10. 10.Enqueue replication server installation for JAVA in Node II

11 Central Instance Installation in Node I

12 Application Instance Installation in Node II

Hi,

when I will have to refresh (homogeneous system copy with backup/restore) my HA Failover Cluster system, what should be the steps?

Do I only need to launch System Copy -> Target System -> HA -> Database Instance?

Hi

Before that have started the Source system export, Kindly refer the video SAP NetWeaver 7.0

Hi,

thanks.

Do I need to switch resources (SAP & SQL) on Node II when I will install Additional MSCS on Node II for example?

Hi

Its not require you can do the normal application instance installation. Dialog instance number should be same as Central instance

Hi,

thanks for your answer.

I will follow the steps mentioned but my question is about options to user with sapinst.exe?

When should I have to usr SAPINST_USE_HOSTNAME?

1. Central services instance for ABAP installation.

  Use the command line sapinst.exe SAPINST_USE_HOSTNAME=FRSERVERSAP

  Note - during the installation time all the cluster resource should be in Node 1

2 First MSCS node installation => on Node I? Do I need to use SAPINST_USE_HOSTNAME=FRSERVERSAP ???

3 Database Instance Installation => Do I need to use SAPINST_USE_HOSTNAME? If yes, do I use FRSERVERSQL???

4 Additional or Second MSCS node installation => on Node II? with SAPINST_USE_HOSTNAME?

Thanks for your help.

Best regards

Hi Durecu

I will follow the steps mentioned but my question is about options to user with sapinst.exe?
When should I have to usr SAPINST_USE_HOSTNAME?

1. Central services instance for ABAP installation.
  Use the command line sapinst.exe SAPINST_USE_HOSTNAME=FRSERVERSAP
  Note - during the installation time all the cluster resource should be in Node 1

During the time of Central service instance for ABAP & JAVA you have to use the Virtual hosts (that is on MSCS SAP Group DNS name, & Cluster disk before that you have to create in MSCS)

Syntax " SAPINST.EXE SAPINST_USE_HOSTNAME=<*Virtual Host Name*> "

2 First MSCS node installation => on Node I? Do I need to use SAPINST_USE_HOSTNAME=FRSERVERSAP ???

Normal SAPINST.exe Without virtual name

3 Database Instance Installation => Do I need to use SAPINST_USE_HOSTNAME? If yes, do I use FRSERVERSQL???

Normal SAPINST.exe Without virtual name

4 Additional or Second MSCS node installation => on Node II? with SAPINST_USE_HOSTNAME?

Normal SAPINST.exe Without virtual name
