Vivek,
This is the kind of question that if you have to ask you are not ready for the answer. The best advice I could give you is to read Nitin Vengurlekar's
"ASM Best Practices" white paper and refer you to Oracle's Cluster Ready
ServicesInstallation Guide. If you've never done this before you should brace yourself for some heavy reading.  

In short to answer your questions the raw devices (LUN's) you want to use for ASM must be shared and visible to all nodes. This is generally done using HBA (host bus adapter) cards that allow your servers to "see and interact with" the SAN storage array. There are some specifics in configuring ASM on Solaris (which slices you can/should use) and which slice to never use. Regarding commands for SAME. This is done by having your storage administrator stripe the volumes across several physical devices. Then you as the DBA come through and configure your ASM volume groups as a combination of these "striped" LUN's. In other words the LUNS are striped on the SAN and the ASM Diskgroups provide a second layer of striping.

Subject: Creation of ASM Disk Group on Solaris 10 ?

Folks  

Need to Setup a 2 Instance ASM-RAC Database from scratch for an internal Test Benchmark.  

• What Commands are used to create an External ASM Disk Group on Solaris 10?
• Any Additional Solaris Commands to make the SAME Disk Group Visible to BOTH SUN Nodes?

NOTE - Disk Group to use External Hardware RAID (10) provided by the Storage Box  

Oracle 10gR2 on Solaris 10  

Any Docs, Links will help  

Cheers & Thanks indeed
