OA66694: DVASSDEV FLAG IN IHADVA MACRO IS NOT REPORTING 'SOLID STATE DRIVES' CORRECTLY WHEN USING THE DEVTYPE MACRO INSTRUCTION.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DVASSDEV flag in IHADVA macro is not reporting SOLID STATE
  DRIVES' correctly when using the DEVTYPE macro instruction.
  
  RDC defines three different bits for Flash (=SSD), currently we
  only check one bit ( RDCSSDEV ) of the three potential
  variations of flash devices.
  Certain variations of flash are not taken into consideration
  when querying the device characteristics.
  As a result, the DVASSDEV flag in IHADVA macro is not set to
  b'1' to indicate a SSD or flash device.
