Nomadic Disk Manager Configuration Statements

Considerations

An alias can be particularly helpful in those installations where the default GIVE
command (see

GIVE Command

on page 7-7) or TAKE command (see

TAKE

Command

on page 7-15) is not appropriate.

A DEFINE need not be a complete command; it can be a partial command. For
example:

ADD DEFINE LDEV LISTDEV

This DEFINE can be used in several ways:

LDEV
LDEV, SEGMENT ONE

A DEFINE can invoke another DEFINE.

ADD DEFINE LDEV LISTDEV
ADD DEFINE DOSTATUS LDEV; STATUS

The ADD DEFINE statement replaces the earlier ADD COMMAND statement.
ADD COMMAND is still accepted.

ADD SEGMENT Statement

The ADD SEGMENT statement adds the definition of a segment to the configuration.

seg

specifies the name of a segment you want to add to the configuration file. You can
use any valid TACL variable name.

DATA

specifies that the segment has Nomadic Disk data and is not a SPARE segment.

SPARE

Do not use this parameter.

Caution.

No syntax checking is performed on the character string when a DEFINE is added,

so it is possible to create DEFINEs that cause an infinite loop when executed.

ADD SEGMENT seg , { DATA | SPARE }
