HMC z/VM Tower systems management enhancements
Building upon the previous VM systems management
support from the Hardware Management Console (HMC),
which offered management support for already defi ned
virtual resources, new HMC capabilities are being made
available allowing selected virtual resources to be defi ned.
In addition, further enhancements have been made for
managing defi ned virtual resources.
Enhancements are designed to deliver out-of-the-box inte-
grated graphical user interface-based (GUI-based) manage-
ment of selected parts of z/VM. This is especially targeted to
deliver ease-of-use for enterprises new to System z.
This helps to avoid the purchase and installation of
additional hardware or software, which may include
complicated setup procedures. You can more seam-
lessly perform hardware and selected operating system
management using the HMC Web browser-based user
interface.
Enhanced installation support for z/VM using the HMC:
HMC version 2.10.1, along with Support Element (SE) ver-
sion 2.10.1 on z10 EC, now gives you the ability to install
Linux on System z in a z/VM virtual machine using the
HMC DVD drive. This new function does not require an
external network connection between z/VM and the HMC,
but instead uses the existing communication path between
the HMC and the SE.
This support is intended for environments that have no
alternative, such as a LAN-based server, for serving the
DVD contents for Linux installations. The elapsed time for
installation using the HMC DVD drive can be an order of
magnitude, or more, longer than the elapsed time for LAN-
based alternatives.
Using the current support and the z/VM support, z/VM
can be installed in an LPAR and both z/VM and Linux on
System z can be installed in a virtual machine from the
HMC DVD drive without requiring an external network
setup or a connection between an LPAR and the HMC.
This addresses security concerns and additional confi gura-
tion efforts using the only other previous solution of the exter-
nal network connection from the HMC to the z/VM image.
Enhanced installation support using the HMC is exclusive
to System z10 and is supported by z/VM.
