    Two questions on ASM for Grid Installation


      Grid Infrastructure version :

      Platform : Oracle Enterprise Linux 5.6





      oracle:dba will be owner of our Grid software (not grid user). What should be permission set for LUNs ( /dev/sda1, ..) before the grid installation ?



      Currently, the shared LUNs appear as


      /dev/sdb ,





      does a single partition need to be created before presenting LUN to ASM ?


      For example, I should choose p (primary partition ) below. Right ?


      # fdisk /dev/sdb

      Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

      Building a new DOS disklabel with disk identifier 0x8b157fd2.

      Changes will remain in memory only, until you decide to write them.

      After that, of course, the previous content won't be recoverable.


      Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)


      WARNING: DOS-compatible mode is deprecated. It's strongly recommended to

               switch off the mode (command 'c') and change display units to

               sectors (command 'u').


      Command (m for help): c

      DOS Compatibility flag is not set


      Command (m for help): u

      Changing display/entry units to sectors


      Command (m for help): n
