Changed Information

The information about adding third party SCSI devices has been replaced with Dynamic Device Recognition (DDR), which performs the same functions. DDR is described in Chapter 6.

The Logical Volume Manager (LVM) appendix has been removed from the manual because the LVM functionality has been retired from the operating system.

Retiring Software

Support for the Logical Volume Manager (LVM) has been retired in this release of the operating system. All volume management functionality now is provided by the Logical Storage Manager (LSM) as described in Chapter 9. All LVM functionality has been disabled with the exception of the support necessary to encapsulate LVM volumes under LSM. All current users of LVM are now required to encapsulate their LVM volumes under LSM in order to maintain access to their data.

Note

In a future release of the operating system, all support for LVM will be dropped and any data remaining under control of LVM software will be lost.

Information about LVM has been deleted from this manual.

Unchanged Information

• Chapter 3, Starting Up and Shutting Down the System, which combines the former chapters about startup and shutdown.

• Chapter 12, Administering the Archiving Services

• Chapter 13, Administering the System Accounting Services

• Appendix C, Support of the CI and HSC Hardware

Organizational Changes

The printed version of the Digital UNIX documentation set is color coded to help specific audiences quickly find the books that meet their needs. (You can order the printed documentation from Digital.) This color coding is reinforced with the use of an icon on the spines of books. The following list describes this convention:

Audience	Icon	Color Code
General users	G	Blue
System and network administrators	S	Red
Programmers	P	Purple
Device driver writers	D	Orange
Reference page users	R	Green

Some books in the documentation set help meet the needs of several audiences. For example, the information in some system books is also used by programmers. Keep this in mind when searching for information on specific topics.

The Documentation Overview, Glossary, and Master Index provides information on all of the books in the Digital UNIX documentation set.
