Chapter 3 Archiving 93

Configuration Guidelines

Although there are no restrictions on where disk archive volumes can reside, it is

recommended that disk volumes reside on a disk other than the one on which the

original files reside. It is also recommended that you make more than one archive

copy and write to more than one type of archive media. For example, you might

archive copy 1 to disk volumes, copy 2 to tape, and copy 3 to magneto-optical disk.

If you are archiving files to a file system on a server system, the archive files

themselves can be archived to removable media cartridges in a library attached to

the server.

Directives for Disk Archiving

When archiving to online disk, the archiver recognizes the archiver.cmd directives

that define the archive set and configure recycling. It ignores directives that

specifically pertain to removable media cartridges. Specifically, the system

recognizes the following directives for disk archive sets:

■ All the recycling directives in “Archive Set Copy Parameters” on page 73 except

for the following:

■ -fillvsns

■ -ovflmin min-size

■ -reserve method

■ -tapenonstop

■ All the directives in “Editing the archiver.cmd File” on page 161 except for the

following:

■ -recycle_dataquantity size

■ -recycle_vsncount count

■ The vsns and endvsns directives and the vsnpools and endvsnpools

directives. Disk volumes are supported in the VSN associations section and are

defined with a dk media type. The volumes are noted by one or more VSN

expression keywords. You can also specify VSN pools from which disk volumes

are to be selected as shown in

CODE EXAMPLE 3-34.
