TerminologyYou should understand what the following terms mean in this document:

xxiv ICKDSF R17 User's Guide

Dedicated device refers to a device dedicated to a virtual machine by either aDEDICATE control statement in the VM user directory or the CP ATTACHcommand.

Device refers to a uniquely addressable part of the DASD unit that includes a setof access arms, their associated surfaces, and the electronic circuitry needed tolocate, read, and write data.

Formatting a volume refers to making a volume usable in a specific operatingenvironment.

Maximal initialization or maximal INIT refers to using the INIT command tocheck the track surface and then perform the minimal INIT. You can only performmaximal INIT on 3370 and 9335 devices.

Medial initialization or medial INIT refers to using the INIT command to validatethe home address and record 0, and then perform a minimal INIT on a volume.

The medial INIT is recommended for 3375 and older devices, such as:v A new DASD unitv A replaced or upgraded head disk assembly (HDA)v A DASD unit that has been physically relocated

For 3380, 3390, and 9345 devices, use the INSTALL command.

Minimal initialization or minimal INIT refers to using the INIT command towrite the volume label and volume table of contents (VTOC) on volumes for useby BookManager® or VSE operating systems.

MVS refers to the OS/390 and z/OS operating systems.

SA refers to the ICKDSF Stand-Alone version.

Volume refers to the DASD space identified by a common label and accessed byany of a set of related addresses.

VM refers to the VM/ESA and z/VM operating systems.

VSE refers to the VSE/ESA operating systems.

Additional terms used in this document are given in the glossary.

How to use this document for your operating environmentThis document is organized for quick retrievability of ICKDSF information.

In addition, icon symbols begin sections, paragraphs, and list items that describespecific ICKDSF versions or operating systems information. An icon, or set of iconsindicates information that is specific to a version or operating system. If placed inthe left margin it references the paragraph to its right, if placed above a section itreferences that section, and if placed in the left margin next to a list item itreferences that list item.

This document is designed so you can discard those pages that do not pertain toyour installation. For example, if you are running exclusively in an MVS
