Installing the A6828A Adapter

Installing the A6828A Adapter

HP recommends that you use SAM instead of the rad command to perform OLAR procedures. This is because for the most part, SAM prevents you from performing OLAR procedures that would adversely affect other areas of the system. This is not true when you use the rad command.

For detailed information on 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 http://www.docs.hp.com.

 

 

Table 2-1 below explains some important OLAR-related terms.

Table 2-1

 

Important OLAR Terms

 

 

 

 

 

 

 

Term

Meaning

 

 

 

 

 

 

OLAR

All aspects of the OLAR feature,

 

 

 

including Online Addition (OLA)

 

 

 

and Online Replacement (OLR).

 

 

 

 

 

 

Power Domain

A grouping of one or more

 

 

 

interface adapter slots that are

 

 

 

powered on or off as a unit.

 

 

 

(Note: Currently, multi-slot

 

 

 

power domains are not

 

 

 

supported.)

 

 

 

 

 

 

target adapter / target adapter

The interface adapter that will be

 

 

slot

added or replaced using OLAR,

 

 

 

and the adapter slot it is in.

 

 

 

 

 

 

affected adapter / affected

Interface adapters and the

 

 

adapter slot

adapter slots they are in, and

 

 

 

which are in the same power

 

 

 

domain as the target slot.

 

 

 

 

 

 

 

 

IMPORTANT

 

In many cases, other interface adapters and slots within the system are

 

 

dependent on the target adapter. For example, if the target adapter is a

 

 

multiple-channel adapter, suspending or deleting drivers for the target

 

 

adapter slot also suspends individual drivers for the multiple hardware

 

 

paths on that adapter.
