Web browser requirements
Learn about the requirements your web browser must meet to monitor
and control the HMC.
To access HMC through a remote browser in a Windows 7 environment,
you must have a minimum/default of 1600x900 screen resolution.
HMC web browser support requires HTML 2.0, JavaScript 1.0, Java™
Virtual Machine (JVM), Java Runtime Environment (JRE) Version 8
U151, 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.
The following browsers have been tested:
Google Chrome
This HMC version supports Google Chrome Version 73 (Official
Build) (64-bit).
Safari
This HMC version supports Safari 11.1
Microsoft Internet Explorer
This HMC version supports Internet Explorer Version
11.0.9600.19326CO.
- If your browser is configured to use an Internet proxy, then
local Internet addresses are included in the exception list.
Consult your network administrator for more information. If
you still need to use the proxy to get to the Hardware
Management Console, enable Use HTTP 1.1 through proxy
connections under the advanced tab in your Internet Options
window.
- It is recommended to have:
- 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%.
- IE doesn't support Promise JS which is the base of the GUI
Dashboard. The UI will fail to update automatically and
may show stale data. To recover:
o Refresh the browser (F5)
o Logoff and re-login to HMC
Mozilla Firefox
This HMC version supports Mozilla Firefox Version 60.5 Extended
Support Release (ESR) and Mozilla Firefox Version 60.6 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.
Safari
This HMC version supports Safari Browser Version 12.0.3

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-HMW or 5765-HMV in
order to download 5765-HMW from the ESS site.
Upgrade of 5765-HMV to 5765-HMW is supported.
Fixes, mandatory fixes and service packs for the vHMC are common
to the Power Hardware management console (HMC) and will be
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
is found in the
IBM
Knowledge Center. Installation procedures may vary depending
on the operating system you use and the hypervisor you use.
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.
Notes for the Virtual Appliance for x86 hypervisors
- The supported hypervisors for x86 are
- VMWARE ESXi 6.0 or higher
- KVM on Red Hat RHEL7 or higher
- Xen 4.2 or higher on SLES 12
- There are now two images for the VMWare ESXi Server, one is
for ESXi 6.0 and the other for ESXi 6.5. This is due to
differences in the encoding of the OVA images. SHA1 for ESXi
6.0 , SHA256 for ESXi 6.5
- The processor on the systems hosting vHMC for x86 must have
either Intel VT-x or AMD-V Hardware Virtualization enabled.

Notes for the Virtual Appliance for PowerVM :
- On Power9 servers, the HMC Virtual Appliance for PowerVM
must run in Power8 compatibility mode, for this release.
- The HMC Virtual Appliance for PowerVM does not
provide graphics adapter support for adapters assign to the
partition. Use a supported web browser to point to the HMC for
UI support.
- DLPAR operations such as memory and processor moves for HMCs
running in an LPAR are not supported.
- Inactive partition migration and Simplified Remote Restart
operations are supported.
- The virtual appliance for PowerVM requires a Power8 or
Power9 server that is enabled for little endian support.
Minimum System Firmware 860 recommended for Power8 servers.
- vHMC for PowerVM cannot manage the server it is hosted on.

General Virtual HMC notes
- Virtual HMC Appliance can be deployed in your existing POWER
virtualized infrastructure. Virtual HMC Appliance supports
install into PowerVM LPARs.
- Call home of serviceable events with a failing MTMS of the
HMC itself is disabled. Those serviceable events should
be manually reported to IBM software support.
- 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.
Example:
lshmc -v
"vpd=*FC ????????

- 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.
- We recommend upgrading to the new image that uses 500GB by
following the steps below:
- From the current HMC version (e.g. HMC V8.860.0),
upgrade to HMC V9 R1 M910
- When the upgrade is complete the HMC is now at a new
version but still has a 160GB disk.
- Perform a Critical Console Data backup, excluding
network information and store the backup to a remote
location.
- Deploy the new HMC V9 R1 M910 image which uses a 500GB
disk.
- After the HMC boots up with the 500GB disk, restore the
Critical Console data.
