Important Olar Terms, Term Meaning | HP HyperFabric instruction

Installing HyperFabric Adapters

	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.
