IC68127: HPUX 11.11-BASED TPC DATA/FABRIC AGENTS INSTALLED ON SAN-ATTACHED DISK DO NOT START AT SYSTEM BOOT.

4.2.1 Interim Fix 1 (November 2011) for Tivoli Storage Productivity Center

APAR status

• Closed as program error.

Error description

• DETAIL OF PROBLEM:
  TPC Data/Fabric agents installed on SAN-attached filesystems on
  HPUX 11.11 servers fail to
  start at system boot due to the agent start script being called
  before the SAN-attached
  drives re-attach to the server.  When the startup process is
  initiated on HPUX and the
  /sbin/rc script is invoked, a list of scripts is created
  containing all the scripts that are
  going to be executed during boot sequence, from all the involved
  run levels.
  Scripts are only added to this list if the scripts referenced by
  symbolic links actually
  physically exist on the system.  Since the Common Agent statup
  script is not available at
  that point due to the SAN disk not being mounted yet, the script
  does not get included in
  the list, and thus the Common Agent does not start during
  bootup.
  A code change is being made that modifies the data agent/fabric
  agent installers to
  dynamically generate the startup script and modify the rc.X
  links.  The script is a wrapper
  which calls the common agent startup script and will be put in
  the HPUX server's /etc/init.d
  file; the way its currently written, it cannot put itself in
  /etc/init.d during install.
  RECREATE STEPS:
  Install A TPC Data and/or Fabric agent on SAN-attached disk on
  an HPUX server then reboot.
  The common agent process will not be launched.

Problem conclusion

• Create a script in /sbin/init.d/ to start the Common Agent.
  Regenerate following links to point to this script:
  /sbin/rc0.d/K71itca0
  /sbin/rc3.d/S71itca0
  /sbin/rc4.d/S71itca0
