HP-UX Installation: HP A7173A PCI-X Dual Channel Ultra320 SCSI Host Bus Adapter
Online Installation

Online Installation
The Online Addition and Replacement feature (OLAR for HP-UX 11i v1, or OL* for HP-UX 11i v2 and later
HP-UX releases) allows 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.
OLAR or OL* may not be supported on the system you plan to install an A7173A adapter in. See the HP-UX
A7173A PCI-X Dual Channel Ultra320 SCSI Host Bus Adapter Support Matrix located at
http://www.docs.hp.com, to confirm if the OLAR or OL* feature is supported.
NOTE For detailed instructions on using OLAR on HP-UX 11i v1, see Chapter 2 of Configuring
HP-UX for Peripherals, which can be accessed at http://www.docs.hp.com
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, which can be
accessed at http://www.docs.hp.com
IMPORTANT Superdome systems are not intended for access by users. HP recommends that Superdome
systems only be opened by a qualified HP engineer. Failure to observe this requirement can
invalidate any support agreement or warranty to which the system owner might otherwise be
entitled.
WARNING If you use OLAR or OL* to add or replace an A7173A adapter, the SCSI ID will be set
at 7 by default. If the SCSI ID for an add-in or replacement adapter needs to be set at
some value other than 7, the mptconfig command can be used to set the SCSI ID after
the A7173A adapter is inserted into the slot and powered on, but before the SCSI
cable(s) are connected. See the HP A7173A PCI-X Dual Channel Ultra320 SCSI Host
Bus Adapter Support Guide for more information
Connecting SCSI Peripheral Devices
Make all SCSI bus connections to the A7173A adapter with shielded, 68-pin cables (multimode, LVD or SE).
The connectors on the cables are always keyed for proper mating.
The A7173A adapter is capable of communicating with Low Voltage Differential (LVD) or Single Ended (SE)
SCSI devices. LVD allows up to 12m cable lengths with multiple SCSI devices, or 25m point-to-point
connections.
