For use with Version 8 Release 8.4.0 SP2

• Fixed a problem with persisted service data that can impact HMC model CR9s.  Symptoms include: all dumps from the managed server being deleted immediately after offload; new serviceable events reported by the server being discarded without a serviceable event being opened on the HMC.
  
• Fixed a problem that caused the wrong HMC machine type, model and serial number to be displayed on the following HMC GUI screens: Service Management -> Enable Electronic Service Agent and Service Management -> Manage Inbound Connectivity -> Prepare -> Remote Service Session.  This problem occurs on CR9 model HMCs only.
  
• Fixed a problem with backup and restore tasks where after restoring a backup and rebooting the HMC users may not be able to login to the HMC GUI and all REST API connection requests are rejected.   After applying this fix,  perform a new HMC backup and discard any older backups.  After a scratch install of the HMC, this PTF should be applied prior to restoring the backup.
  
• Fixed a rare timing issue that can cause a partition migration operation to incorrectly fail with error "HSCL2957 Either there is currently no RMC connection between the management console and the partition <target partition> or the partition does not support dynamic partitioning operations" even though the RMC connection is actually active. 
  Circumvention: Confirm that the HMC lssyscfg -r lpar -m <managed system name> -F rmc_state command shows the RMC connection is active then try the partition migration operation again.
  
• Fixed an issue where system initiated System Dump files were not being automatically called home.
  
• Fixed a problem where some GUI views of system firmware levels such as the Updates,  System Code Levels table incorrectly show a deferred level of none (or blank) when a deferred level exists.    
  
• Fixed a problem that resulted in a false report of SRC E2FF1801 and SRC E2FF1800.  These SRCs typically occur when running the software or performance inventory tasks on an HMC that is managing a large number of servers even though the inventory tasks complete successfully.
  
• Fixed an issue causing the update of I/O device microcode from IBM microcode CD/DVD to fail with "HSCF0179W Operation was partially successful for <target>.An error occurred while attempting to update I/O microcode on <target>:An error occurred copying a file from the CDROM.  First verify the correct media is inserted in the drive, that there is space available on the target system, then try the operation again."
  
• Fixed a problem that caused E2FF4304 SRCs to be generated during HMC PTF installation.
  
• Fixed a problem with the vterm console window on the local HMC console that prevented the window from resizing when the font size for the window was made larger.  This problem could prevent the user from being able to see the entire contents of the console window.
  
• Fixed a rare error that can occur when the HMC is processing a property change event for a tree node representing a managed object or group while a managed system is being added to the HMC.  This error caused SRC E3551040 to be generated and called home.
  
• Fixed a problem causing partition migration operations performed by PowerVC to fail when the ibmpowervm_mover_service_partitions attribute is specified in the nova.conf files.  This problem occurs only with Virtual I/O Server versions 2.2.4 and later.
     
  

• Fixed IBM Websphere Application Server (WAS) vulnerabilities: CVE-2016-0378 and CVE-2016-5986.
  
• Fixed Apache Tomcat vulnerability: CVE-2016-3092.
  
• Set the X-Frame-Options HTTP response header from all HMC /dashboard URLs to instruct the browser to not allow framing from other domains. This change is intended to prevent Clickjacking attacks.
  
• Disabled TLS 1.0 for HMC ports 443, 9920 and 9960 in legacy security mode.

Notes:

1. The Install Corrective Service task now allows you to install corrective service updates from the ISO image files of these updates. You can download these ISO image files for the HMC, and then use the ISO image file to install the corrective service update. You no longer need to burn CD-R or DVD-R media to use the ISO image file to install corrective service.
2. This image requires DVD -R media.
3. To install updates over the network, select the *.iso file on the "Select Service Package" panel of the Install Corrective Service task. The HMC application extracts the files needed to install the corrective service. If you are using USB flash media, copy the *.iso file to the flash media, and then select the file when prompted.
4. The updhmc command line command has also been modified to use the *.iso file. To use the command, follow the syntax in this example:
   updhmc -t s -h <myservername> -f </home/updates/corrrective_service.iso> -u <HMC_username> -i

In all cases, the HMC application extracts the files needed to install the corrective service.
