VM66504: PREREQUISITE SUPPORT FOR ANY FUTURE PROCESSOR

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• APAR VM66504 provides infrastructure support to prepare a
  Single System Image (SSI) cluster that may include any future
  IBM Z server and must be installed on all members of the SSI.
  Installation of this APAR must be done before any member of the
  SSI cluster will be running on a new server.

  This APAR accommodates a larger facility list length that
  may be presented on a new server. Support of the larger
  length on all members of an SSI cluster ensures members with
  different list lengths are compatible, and avoids unnecessary
  trapping and simulation of the STFLE instruction on existing
  members.
  
  Compatibility checking is adjusted so that a guest running
  on an existing member can smoothly relocate to and from a
  new server once it joins the SSI cluster and the guest's
  relocation domain. Without this APAR on existing members, the
  lack of obsolete architectural facilities on a new server
  could unnecessarily impede such relocation.
  
  Additionally, z/VM's dependency on the
  Load-Program-Parameter (LPP) facility is now enforced on
  z/VM release 7.2 during CP initialization. This facility is
  already included in the 7.2 architecture level set and is
  present on all IBM processors supported by z/VM 7.2.

Comments

• A new server that is added as a member to an SSI cluster
  may introduce some incompatibilities with existing servers.
  To avoid any potential problems, this APAR adds support to
  ensure the new server may be a part of the SSI cluster
  and eligible for Live Guest Relocation (LGR).
