IJ32439: CONFIGRM FAILS IF RSCT.BASIC.RTE NOT INSTALLED

APAR status

• Closed as fixed if next.

Error description

• IBM.ConfigRM is an RSCT subsystem primarily responsible
  for handling "Peer Domain" configurations, supporting
  products like PowerHA SystemMirror and "SAMP" (System
  Automation for Multi-Platform).  It is also needed for
  AIX Live Kernel Update (LKU).
  
  It is installed as part of rsct.core.rmc, but has always
  needed the support of the rsct.basic.rte package to
  perform any of its real work.  (rsct.basic filesets are
  automatically installed if supporting LKU or either of
  the above-mentioned products.)
  
  Starting in AIX 7.2 TL04 SP2 (RSCT 3.2.5.1), a new
  startup dependency was added to ConfigRM as part of
  support for a restart grace period for failing cthags
  clients (including ConfigRM), primarily intended for
  use in PowerHA cluster solutions.
  (Note: Most of this new functionality was introduced
  in the GA of TL04, with RSCT 3.2.5.0.  But the new
  dependency did not become effective until 3.2.5.1
  because of some build issues in the 3.2.5.0 delivery.)
  
  Prior to this, on AIX installations not actively using
  IBM.ConfigRM, the subsystem would simply run without
  doing anything, waiting for its services to be needed.
  With this new dependency, unfortunately, it will fail
  to start if the rsct.basic.rte subsystem is not
  installed, creating several SRC errors in the errpt
  as srcmstr tries to restart it up to its restart limit.
  
  The errors are only visible to customers  who are using
  the most minimal of AIX install images, which cannot
  support LKU, and does not include the rsct.basic
  package sets by default.
  

Local fix

• Customers without rsct.basic filesets are not dependent
  on any of IBM.ConfigRM's functionality anyway, and can
  either install the rsct.basic packages from their AIX
  installation media, or ignore the SRC errors related to
  IBM.ConfigRM.
  
  A temporary ifix will also be provided for the affected
  7.2 TLs, for customers with high security concerns, who
  cannot install new packages on short notice, and also
  find the additional errors unacceptable.
  

Problem summary

• IBM.ConfigRM in RSCT 3.2.5 can no longer even start if the
  rsct.basic filesets are not installed.
  Future AIX installations will always include rsct.basic.
  

Problem conclusion

Temporary fix
