    Two questions on ASM for Grid Installation

    greeny

      Grid Infrastructure version : 11.2.0.3

      Platform : Oracle Enterprise Linux 5.6

       

       

      Question1.

       

      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 ?

       

      Question2.

      Currently, the shared LUNs appear as

       

      /dev/sdb ,

      /dev/sdc,

      /dev/sdd

       

       

      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.

               sectors (command 'u').
