Problem conclusion

Temporary fix

Comments

• PRODUCT ENHANCEMENT
  This APAR provides new function support for using a single parm
  disk on z/VM systems running in a GDPS/PPRC configuration.  The
  function eliminates the requirement to use two separate parm
  disks for stand alone z/VM systems or Single System Image (SSI)
  clusters which have their PPRC secondary devices in an alternate
  subchannel set (MSS1).
  The function is applicable to all GDPS/PPRC environments running
  xDR for z/VM with the z/VM PPRC secondary devices in alternate
  subchannel set (MSS1) includidng 3-site and 4-site MGM and MzGM
  configurations.
  
  DOCUMENTATION CHANGES
  Chapter 3 in the GDPS/PPRC Extensions for Heterogeneous
  Platforms manual (ZG24-1753) is revised to provide implemen-
  tation, migration, and fallback information. See PTF DOC hold
  for details.
  
  PRODUCT DEPENDENCY
  Implementing single parm disk support for xDR also requires
  Tivoli System Automation for MultiPlatforms (SA MP) v4.1.0.2
  with APAR (IV77608) or higher. Also, any z/VM system which is
  using single parm disk support in a MSS0/MSS1 configuration must
  be run on z Systems hardware that supports five digit IPL
  addresses.
  
  MULTIPLE SYSTEM CONSIDERATIONS
  This PTF must be applied to both GDPS/PPRC controlling systems
  prior to exploiting xDR single parmdisk support.
