Thks Mike,    

  What am finding confusing is the following statement (from Oracle Clusterware and Oracle Real Application Clusters Installation Guide 10g Release 2 (10.2) for Solaris OS - B14205-03), page 3-13 Configuring Database File Storage on ASM and Raw Devices.    

  To use ASM with raw partitions, you must creatre sufficient partitions for your data files, and then bind the partitions to raw devices.    

  The question is how does the sysadmin do this when all he has is 50GB of SAN storage. I know this is more of unix question, but i can't get my head round this. We are not using any LVM.    

  Also i presume you have installed your ASM instance in it's own ORACLE_HOME.

  Am trying to get my head round on how to configure the disk storage so that i can use this for my ASM RAC database.    

  I've got in total 50GB on a HDS SAN (RAID5) to play with. My question is how do i configure this so that i can use the storage for my ASM disk group(s).    

  Do i ask the sysadmins to create me a 50GB raw partition?    

  TIA
