For use with Version 8 Release 8.6.0

These special instructions contain the following information specific to HMC V8 R8.6.0 code level.

PTF MH01654 HMC V8 R8.6.0 Recovery Media and Mandatory PTF MH01655

This package represents the Recovery Media that can be used to upgrade your HMC from HMC V8 R8.4.0 or later to HMC V8 R8.6.0. This package can also be used to install a clean version of HMC V8 R8.6.0. 

The Mandatory PTF must be installed after you upgrade to HMC V8 R8.6.0 or after a new installation of HMC V8 R8.6.0 in order to be in a supported configuration.
You can reference the Recovery image by APAR MB04039 and PTF MH01654. The Mandatory PTF is APAR MB04040 and PTF MH01655.

Note 1: During the installation, the screen can pause or go blank. Press the space bar / scroll-lock to activate the display again.

Note 2: If the HMC is upgraded from the V8 R8.4.0 or V8 R8.50 release, reboot the HMC a second time to initialize the swap space. Otherwise, the HMC will report serviceable event SRC E212E11C.

Note 3: If the HMC is configured to use LDAP authentication and the LDAP server uses the rfc2307aix LDAP schema, ensure that the LDAP server is configured so that all HMC LDAP users have permission to search and read their own entries.  Without these permissions, HMC LDAP users will not be able to log in to the HMC after upgrading the HMC to V8 R8.6.0.  For information on how to validate the configuration prior to upgrading see IBM Support document "V8R8.6 HMC: Changes to LDAP authentication" at http://www.ibm.com/support/docview.wss?uid=nas8N1021717

Note 4:  IBM is investigating a rare issue where the HMC upgrade may indefinitely hang at "Processing SaveHSCSystemUpgradeData.tar ....."  
As an additional precaution, you may wish to manually record settings prior to the upgrade so that the HMC could be rebuilt from a scratch install of V8 R8.6.0 if needed. 
For a list of recommend settings to record see http://www.ibm.com/support/docview.wss?uid=nas8N1011269     
Allow at least one hour before attempting recovery.  Power off and power on the HMC.   The HMC should retry the restore.  If the restore hangs a second time then the HMC must be re-installed.

Web browser requirements

Learn about the requirements your web browser must meet to monitor and control the HMC.

HMC web browser support requires HTML 2.0, JavaScript 1.0, Java™ Virtual Machine (JVM), Java Runtime Environment (JRE) Version 8 U71, and cookie support in browsers that will connect to the HMC. Contact your support personnel to assist you in determining if your browser is configured with a Java Virtual Machine. The web browser must use HTTP 1.1. If you are using a proxy server, HTTP 1.1 must be enabled for the proxy connections. Additionally, pop-ups must be enabled for all HMCs addressed in the browser if running with pop-ups disabled. It is necessary to clear the browser cache during upgrade as javascript and css information is cached.

The following browsers have been tested:

Google Chrome

HMC Version 8.6.0 supports Google Chrome Version 48.


HMC version 8.6.0 supports Safari Version 9.1.1 (11601.6.17).

Microsoft Internet Explorer

HMC  V8 R8.6.0 supports Internet Explorer 11.0.
  • Browser security setting in internet zone. If you are running security mode in "Local intranet" mode, make sure you do not have any setting to detect intranet network; disable Compatibility view.
  • Browser zoom setting to 100%.

Mozilla Firefox

HMC Version 8.6.0 supports Mozilla Firefox Version 38 Extended Support Release (ESR) and Mozilla Firefox Version 45 Extended Support Release (ESR). Ensure that the JavaScript options to raise or lower windows and to move or resize existing windows are enabled. To enable these options, click the Content tab in the browser's Options dialog, click Advanced next to the Enable JavaScript option, and then select the Raise or lower windows option and the Move or resize existing windows options. Use these options to easily switch between HMC tasks. For more information about the latest Mozilla Firefox ESR levels, see Security Advisories for Firefox ESR.

Special Install Instructions for mandatory fix MH01655:  This fix must be installed using either the classic GUI or the HMC updhmc command; not the enhanced GUI.  See the updhmc “man” page (e.g. man updhmc) for further information and examples on using the command.

Installation instructions for HMC Version 8 upgrades and corrective service can be found at these locations:

Installation methods for vHMC

After the upgrade, install the mandatory fix using the instructions at:
Installation methods for HMC Version 8 fixes

Virtual HMC (vHMC)

The vHMC provides images in 3 additional formats to allow for quick deployment of the vHMC on either ESXi, KVM or Xen hypervisors. These images are snapshots of the virtual machine and allow for quick deployment of the HMC.

The mandatory PTF (MH01655) that is referenced earlier in this document is required in order to be in a supported configuration

A feature of the vHMC is the activation engine which allows you to preconfigure the HMC Console by passing configuration information to the HMC at the first boot of the HMC, when using these images.
Please look at the on-line Knowledge Center documentation on using the Activation Engine feature.
  • To see if you are running on a virtual HMC use the lshmc -v command. If it displays a UVMID field, then you are running in a virtual machine.
lshmc -v

  • When deploying a virtual HMC, if the mac address is not specified, it will be generated by the hypervisor.  Network configuration on the HMC relies on the value of MAC addresses. If you re-deploy a new virtual HMC and want to restore critical console data previously taken on a virtual HMC, ensure sure you are using the same MAC addresses.
  • When using Activation Engine to setup NTP configuration, you must specify the NTP version value.

vHMC Installation Images

Download of the Power Hardware Management Virtual Appliance (vHMC) install images are available at the Entitled Systems Support site (ESS): http://www-304.ibm.com/servers/eserver/ess/OpenServlet.wss.  You must be entitled to Product ID 5765-HMV in order to download from the ESS site.

The vHMC vmware ova images are built with the SHA1 hash algorithm which is supported by vmware 6.0 and earlier.

Fixes, mandatory fixes and service packs for the vHMC are common to the Power Hardware management console (HMC) and are available at IBM Fix Central.

The splash panel information (lshmc -V output) for the vHMC will be the same as for the HMC recovery DVD that is documented in the above description section.

Installation guidance for installing the vHMC into your hypervisor are found in the online Knowlege Center. Installation procedures may vary depending on the operating system you use and the hypervisor you use.

The mandatory PTF must be installed immediately after installing the virtual machine image.  The Mandatory PTF is available on Fix Central.
