Chapter 3

There are two methods to add or replace OLAR-compatible cards:

• Using the SAM utility.

• Issuing command-line commands, through rad, that refer to the HyperFabric OLAR

script (/usr/sbin/olard.d/clicd).

HP recommends that SAM be used for OLAR procedures, instead of the rad command.

This is primarily because SAM prevents the user from doing things that might have

adverse effects. This is not true when the rad command is used.

For detailed information about using either of these two procedures, see Configuring

HP-UX For Peripherals. You can order that document from Hewlett-Packard, or you can

view, download, and print it from this URL: http://www.docs.hp.com.

Table 3-1 below explains some important OLAR-related terms.
