A.19.2 set attribute

The

set attribute

command creates a system attribute and/or sets the value of the attribute. You can

only set the values of certain attributes.

In most cases, the new attribute or value does not come into effect until you configure servers or reconfigure

file systems. The

set attribute

command prints a message describing the action that is needed to bring

the new attribute or value into effect.

TIP:

The

set attribute

command is the same as the

create attribute

command.

Syntax

set attribute attribute_name=attribute_value

Arguments

attribute_name

Required. Specify the name and value of a new or existing attribute.

If the attribute value contains spaces, enclose the value in double quotes.

Example

The following example creates the

nickname

attribute and sets its value to

west

:

sfs> set attribute nickname=west
