SGeSAP storage layout

[Ibnelhaj Fouad]

Hi Guys,

I am currenty setting up the storage layout for a SGeSAP cluster with 4 nodes and two SAP systems. which means that we have 2 dbci packages called CRM and ISU and a third sapnfs package. 2 out of the 4 nodes will hold the application servers. These will be shutdown if the dbci package fails over to the application server node .


The customer is asking about the following :
Is it recommended to install the oracle binaries on each node?

Is it recommended to have a local copy of SAP executables on each node ?

Is it possible to use one /usr/sap/trans for both SAP instances and put the sapnfs package?

should we create /usr/sap/put on each node. or only one on a shared disk and mount it on the node where it is needed ?

Hi Ibnelhaj,

I would read all of the documentation at this url: http://docs.hp.com/en/ha.html#Serviceguard%20Extension%20for%20SAP

It should answer all of your questions.

Oracle binaries: yes
SAP Executables: see SAPcpe
/usr/sap/trans shared through sapnfs: yes
/usr/sap/put on each node: yes

HTH,

Keith

Just a thought... if the application programs are on a shared disk and that disk dies, no server will be able to execute the application, and Serviceguard will be moot at that point.

Thanks guys for your answer.

where /oracle/ should be placed - on sapnfs package or on dbci package, knowing on 2 nodes of the cluster I have application servers also installed ( but they are outside the cluster ).
