HP Fibre Channel Mass Storage Adapters Support Guide, February 2007

Chapter 2

Fibre Channel Adapter Installation

Installing Adapter Hardware

The Online Addition and Replacement feature, OLAR for HP-UX 11i v3, or OL* for HP-UX 11i v2 and later

HP-UX releases, enables PCI host bus adapters to be added or replaced without shutting down and rebooting

the system, and without adversely affecting other system components. The system hardware uses slot-specific

power control, combined with HP-UX operating system support, to enable these features.

Confirm whether OLAR or OL* are supported on the system in wich you plan to install a Fibre Channel

adapter. See the HP Fibre Channel Host Bus Adapter Support Matrix, at:

http://docs.hp.com/en/netcom.html#Fibre%20Channel

For detailed instructions on using OLAR on HP-UX 11i v3, see Chapter 2 of Configuring HP-UX for

Peripherals, which can be accessed at:

http://docs.hp.com/en/hpux11i.html

For detailed instructions on using OL* on HP-UX 11i v2 and later HP-UX releases, see the Interface Card

OL* Support Guide and the Interface Card OL* Support Matrix at:

http://docs.hp.com/en/hpux11iv2.html

NOTE HP rp54xx servers have slot restrictions for OLAR.

PCI slots 1 through 4 do not support OLAR. In these servers, use PCI slots 5 through 12 for

OLAR.

IMPORTANT Superdome systems are not intended to be maintained by customers. HP recommends that

Superdome systems only be opened by a qualified HP service engineer. Failure to observe this

recommendation can invalidate any support agreement or warranty to which you may be

entitled.

Table 2-2 summarizes the PCI slot numbers that are compatible with Online Addition and Replacement for

select HP server products.
