          The log format for Oracle ASMLib that is
          used to manage Oracle Automatic Storage Management (ASM)
          devices dedicated to Oracle Databases has been updated to
          include timestamps of the activities that are logged to
          /var/log/oracleasm.
          
        
          The oracleasm command is improved for the
          scandisks operation so that it is able scan
          devices that are not directly available under
          /dev, but could be available within
          subdirectories within /dev. You can
          configure additional directories to be scanned during the
          scandisks operation by setting the
          Directories to scan option when using the
          interactive configuration tool, as shown in the following
          example:
        
#oracleasm configure -IConfiguring the Oracle ASM library driver. ... The next two configuration options take substrings to match device names. The substring "sd" (without the quotes), for example, matches "sda", "sdb", etc. You may enter more than one substring pattern, separated by spaces. The special string "none" (again, without the quotes) will clear the value. .
