PH19670: UPGRADING IDAA V7.1 ON IIAS TO MAINTENANCE LEVEL '7.1.9' MAY BRING THE SYSTEM DOWN

APAR status

• Closed as unreproducible.

Error description

• In rare situations upgrading IDAA V7.1 on IIAS to maintenance
  level '7.1.9' may bring the system down.
  The IDAA maintenance level from where the upgrade was started is
  no longer operational.
  .
  From an IBM support point of view the insights into
  situation unveil the following:
  a) The kernel of the IIAS system was upgraded
  b) The subsequent upgrade of the GPFS (General Parallel File
  System) component failed.
  
  This version mix of kernel and GPFS requires manual intervention
  by IBM support.
  Attention:
  A restart of the appliance (apstop/apstart) will NOT heal the
  situation.
  .
  The underlying malfunction in the IIAS installation script was
  fixed and integrated into the new maintenance level 7.1.9.1.
  For downloading the 7.1.9.1 package see

Local fix

• IBM support needs to perform a so-called essential upgrade to
  neither upgrade kernel nor GPFS.
  

Problem summary

  to maintenance level '7.1.9' may bring the system down.
