APAR status

• Closed as new function.

Error description

• This support allows the LUN operand to be optional.
  The LUN operand is optional on the SET EDEVICE command and the
  EDEVICE system configuration statement after the first path has
  been established.

Comments

• Code has been updated to add support for specification of the
  LUN optional after the first path has been established.  The
  following documentation changes have been made.
  
  SC24-6268-06 z/VM: CP Commands and Utilities Reference
  SET EDEVICE command
  The following note has been added regarding the LUN operand
  
  The LUN operand is required when you define the first path to
  an EDEVICE.  For subsequent paths, the LUN operand is optional.
  If you specify the LUN operand, the value must match the LUN on
  the first path.
  
  Response 8 has also been added
  
  To define an emulated device 5004 for a 2145 device with two
  paths where LUN is optional on the second path, enter the
  following:
  
  set edev 5004 type fba attr 2145
    fcp_dev 800 wwpn 200400A0B80BA687 lun 0002000000000000
    fcp_dev 801 wwpn 200400A0B80BA688
  EDEV 5004 was created.
  Ready;
  
  GC24-6270-06 z/VM: CP Messages and Codes
  HCP8703E
  A third variation of message HCP88703E has been added.
  
  - Variation 3 The LUN lun specified does not match the LUN that
  is already associated with EDEV rdev.
  
  Explanation:
  
  A path was specified with the SET EDEVICE command or EDEVICE
  system configuration statement and the LUN does not match the
  LUN that is already associated with the EDEVICE.
  
  System action:
  
  The path is not added to the emulated device definition. System
  operation continues.
  
  User response:
  
  Issue a CP QUERY EDEVICE command to determine the LUN associated
  with the EDEVICE. Issue a CP SET EDEVICE command with the
  correct LUN.  If the EDEVICE was incorrectly defined in the
  system configuration file, update the LUN in the EDEVICE
  system configuration statement.
