This issue has been solved. See solution.

Dear All,

I am planning to setup two node SFRAC in AIX server. I quite confidence about normal veritas cluster products. But, I got confused about RAC setup in veritas.

Following are my setup environment.

Server :

1) 2 * AIX 7.1 node

2) Created separate /oracle11gr2 file system locally to install RAC binaries

3) each node has 3 network interface. I already setup 2 interface for LLT between two nodes. Remaining one interface assigned to server IP address.

Kindly let me know my pre-requisites for SF RAC with CFS

1) How many VIP now I require per node ?

2) Do I need SCAN IP ? if Yes then I prepare 3 IP for that.

3) Planning to Keep OCR & Voting disk in CFS. Do I need to keep separate Vg for that ? if yes then minimum how many disk need for vg & how many file system need to create?

4) Do I need to configure any additional Resources or link (parent child) vg ?

For data files, logs and archive, I will create separate CFS .

Do we have any sample step by step documents for install & configure ? Please kindly help me.

Thanks,

Jay

Please find my answers highlighted below.

1) How many VIP now I require per node ?

You need 2 public vips , each per node. You need to add the vips in /etc/hosts for both the nodes.

2) Do I need SCAN IP ? if Yes then I prepare 3 IP for that. 

Yes you need SCAN IP and it should resolve to 3 public ips.

3) Planning to Keep OCR & Voting disk in CFS. Do I need to keep separate Vg for that ? if yes then minimum how many disk need for vg & how many file system need to create? 

You can keep mirror volumes for both ocr and vote files. You can create ocr/vote dgs and CFS using product configure script : # /opt/VRTS/install/installsfrac -configure and follow the instructions. Follow Storage Foundation for Oracle RAC install and configuration guide in https://sort.symantec.com/documents for the details.

4) Do I need to configure any additional Resources or link (parent child) vg ? 

You can check for sample main.cf configrations in /opt/VRTSvcs/conf/sample_rac/ which will help you.

For data files, logs and archive, I will create separate CFS . 

Yes sounds good. 

Do we have any sample step by step documents for install & configure ? Please kindly help me. 

Follow Storage Foundation for Oracle RAC install and configuration guide in https://sort.symantec.com/documents.

Also please ensure to run the checklist before installing SFRAC https://sort.symantec.com/sitemap/checklist/SFRAC.

Dear Experts,

I guess finally completed most of the work to confogure SFRAC for AIX. Kindly correct me if some mistake on below setups.

below service groups created while part of configuration using installer script.

servergroups:-

ClusterService ==========> hold web IP and only online in one host (what is the use of this sg & IP ?)     
cvm           =============> hold cvm,voting related cvm and cfs (online on both node)
vxfen          ============> fencing disk dg (online on both node)
 

Task completed:

1) Oracle clusterware installed (installed in local fs on both node)

2) oracle binaris installed (installed in local fs on both node)

3) configure cssd agent

4) relink oraacle db binaries

For create db files i manually created dg,vol,mount point and added using cfsmntadm. Also created sg,res for same and now online in both node.

My question is :

1) do i need to link oradata_sg (datafiles) to any other sg which already created by installer ?

2) Any IP related sg or res need to configure ? (i guess oracle clusterware already did & taking care)

3) any other steps Do i need to follow from system & DB side ?

4) After created sg for datafiles mount points  I can see one more SG (vrts_vea_cfs_int_cfsmount1) automatically showing. Is it created cfsmntadm ? I can see two sg in main.cf for same mount point
