Install techniques for z/VM


  • Traditional installation installs a new z/VM system or SSI cluster on a set of DASDs, which can be customized.
  • Upgrade installation uses a temporary work system installed as a second level guest of the current release to be upgraded. The new level of code from the work system is then moved to the current system with minimal impact to the current running system.

Which technique to use?

  • New to the IBM z/VM operating system or installing a new system, use the traditional installation method. The z/VM Installation Guide for the release being installed will provide all the required information. A copy of the z/VM Installation Guide is included with the product order. It can also be referenced based on the release to be installed using the 'Change version or product' drop down from the IBM Documentation Center.
  • Looking to upgrade to the next available z/VM release? Find out if upgrade is right for your installation and understand the requirements for Upgrade In Place.

z/VM V7 Installation Media

Once you have placed a z/VM product order, it will arrive as a set of download links. The installation media deliverable will include:

  1. z/VM System Image (either 3390 or SCSI). The System Image is on two ISO files.
  2. z/VM Recommended Service Upgrade RSU. The first RSU for a release is delivered on Disc 2 of your product order and is installed automatically.
  3. Any optional priced features User Memos or IBM licensed products ordered.
  4. Instructions for receiving you order. The instructions for downloading your product materials are found in the z/VM download instructions.
  5. The z/VM Installation Guide

If you are upgrading you may have individual service (PTFs/APARs) on the system to be upgraded that is not included in the new level of z/VM. You can use the z/VM 7.3 CHKAPARS or z/VM 7.4 CHKAPARS tool to verify whether all service you have is included in the new level of z/VM.

NOTE: It can't be stressed enough that reading and planning is critical to the success of both traditional installation and upgrade installation. Please read the z/VM Installation Guide and fill out all applicable worksheets.
