Installing the z/OS volume images

The downloaded z/OS® volume images are in the ZPD and gz file extension formats. ZPD files require installation by using the Z1091_ADCD_install command, and are stored with a name volser.ZPD. All other z/OS volume images are compressed files that are stored with a name volser.gz, requiring only the gunzip command for installation. In both cases, volser is a six character volume serial of the z/OS volume. In z/OS Version 2 Release 2, only 2 IPL volume images require installation by using the Z1091_ADCD_install command: D2RES1.ZPD and SARES1.ZPD.

The process of installing the z/OS volume images is to use the Z1091_ADCD_install command to install ZPD volume images, and use the gunzip command to decompress any other z/OS volumes needed. When installed or decompressed, most volumes are in emulated 3390-9 format, which are approximately 8.5 GB. Run all commands as the user that runs ZD&T, in this example ibmsys1.

Perform the following two commands to install the ZPD volume images into the /home/ibmsys1/z1090/disks directory:

$ Z1091_ADCD_install /home/ibmsys1/z1090/D2RES1.ZPD /home/ibmsys1/z1090/disks/D2RES1
$ Z1091_ADCD_install /home/ibmsys1/z1090/SARES1.ZPD /home/ibmsys1/z1090/disks/SARES1

Perform these three commands to decompress all other z/OS volume images in that directory, and give the correct permissions for all z/OS volume image files.

Note: For some images, the gunzip command might produce a message about an unexpected end of file. If the *.gz files were correctly downloaded, that message can be safely ignored. Also, the gunzip command as shown here deletes the original .gz files. To keep the original file, enter gunzip -k *.gz. The -k parameter is available on later versions of gunzip.

$ cd /home/ibmsys1/z1090/disks
$ gunzip *.gz
$ chmod 755 *

All MVS™ volume images are in /home/ibmsys1/z1090/disks.

Most of these products and subsystems run without any customization, and some need some customization or initialization to make them work. The customizations to establish TCP/IP connectivity and update the infrastructure to allow z/OS 2.2 to properly run on ZD&T are described in ADCD.
