      1  Changes in SIR concerning RAID support
      -----------------------------------------
  
      Note 2 concerning RAID support in the system installation
      manual in chapter 7.1 on page 172 has to be extended as
      follows:
  
        SIR could not recognize the current RAID state for disks 
        with FBA block structure. If a disk with block structure FBA 
        is specified to install or extend a pubset, the specified 
        disk is added to the pubset without any user interaction.
  
        For a pubset, which includes one or more disks with block 
        structure FBA, SIR shows always NORMAL as RAID state in its 
        pubset overview screen.

      2  Changes in IOGEN concerning FC configuration 
      -----------------------------------------------
      
      With the changes in IOGEN concerning PM-number A0535529 the
      restrictions for creating device addresses in  FC con-
      figurations are weakened. 
      The restrictions for creating device addresses on channel type
      IBF,MODE=FCP as described in the manual System Installation
      [1] chapter 4.4.7 on page 65 therefore have to be changed as
      follows:
  
      Restrictions under 1. and 2. remain unchanged.            
      The restrciction described under 3. has to be replaced by:  
  
         If multiple logical controllers with the same World-Wide 
         Port Number are connected, the Logical Unit Numbers
         of all devices connected to these controllers must be
         unique.
         This can be reached by using different high-order bytes
         in the Logical Unit Numbers of the attached devices
         for each controller with the same World-Wide Port Number.
         But it is also possible to devide devices with identical
         high-order byte in their Logical Unit Numbers into different
         logical controllers with the same World-Wide Port Number.
         Devices then must differ in the low-order byte of the 
         Logical Unit Numbers.

      3  Changes in file commands for coded character set
      ---------------------------------------------------
  
      For the SDF commands CREATE-FILE, MODIFY-FILE-ATTRIBUTES, 
      CREATE-FILE-GROUP, MODIFY-FILE-GROUP-ATTRIBUTES, a new value
      *USER-DEFAULT is assigned to the operand CODED-CHARACTER-SET. 
  
      This value becomes default definition for the commands 
      CREATE-FILE and CREATE-FILE-GROUP. 
  
      Specification of the new value *USER-DEFAULT in the commands 
      as well as 
      specification of CCS=*STD in the program interface CATAL or
      with creation of a new file in the program interface FILE 
      has this effect: 
  
      The Coded Character Set is taken from the User Catalog of 
      the corresponding User-ID in the referenced pubset, if not 
      equal EDF03IRV - otherwise no Coded Character Set is entered.
