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.
