About This Installation Guide Who Should Use This Installation Guide Who Should Use This Installation Guide This installation guide provides installation instructions and technical information for qualified personnel who maintain or service HP-UX systems. This guide includes information on installing HP A6828A PCI Single Channel and HP A6829A PCI Dual Channel Ultra160 SCSI Host Bus Adapters.
2 Installing the A6828A or A6829A Adapter This chapter contains the following sections that describe how to install the A6828A or A6829A adapter: Chapter 2 3
Installing the A6828A or A6829A Adapter NOTE 4 • “Preparing for Installation” on page 5 • “Installing the Adapter” on page 6 • “Verifying Installation” on page 12 • “Additional Information” on page 14 Installing the adapter requires proficiency in both hardware configuration and software administration.
Installing the A6828A or A6829A Adapter Preparing for Installation Preparing for Installation Installation of an adapter requires disassembly of a few system components. Before beginning the installation, see the HP-UX system’s manual for detailed instructions on installing host bus adapters in the PCI slots.
Installing the A6828A or A6829A Adapter Installing the Adapter Installing the Adapter This section contains information on installing the A6828A or A6829A adapter in an HP-UX system. In addition, it includes information on Online Addition and Replacement (OLAR). WARNING The installation procedures in this section require opening the computer cabinet, which might expose you to high-energy (high-amperage) circuits and sharp edges in the equipment chassis.
Installing the A6828A or A6829A Adapter Installing the Adapter Install the adapter in your HP-UX system according to the documentation for the system. NOTE Although the A6828A or A6829A adapter is supported on only 64-bit HP-UX 11.0 and 11i, you can install the adapter in either a 32-bit or 64-bit PCI slot. In addition, HP recommends using a PCI4X or PCI2X slot to get maximum performance. However, you can install the adapter in a PCI2X, PCI1X, or shared PCI slot, if necessary.
Installing the A6828A or A6829A Adapter Installing the 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.
Installing the A6828A or A6829A Adapter Installing the Adapter During an adapter replacement operation, SAM performs a Critical Resource Analysis (CRA), which checks all channels on the target adapter for critical resources that will be temporarily unavailable while the adapter is shut down. Planning and Preparation As mentioned earlier, for the most part, SAM prevents you from performing OLAR procedures that would adversly affect other areas of the HP-UX system.
Installing the A6828A or A6829A Adapter Installing the Adapter Adapter Compatibility This section explains adapter compatibility considerations for performing OLA and OLR. Online Addition (OLA) You can add multiple adapters at the same time. While adding an adapter online, the first issue you must resolve is whether the new adapter is compatible with the system. Each OLAR-capable PCI slot provides a set amount of power. The replacement adapter cannot require more than the available power.
Installing the A6828A or A6829A Adapter Installing the Adapter The PCI specification enables a single physical adapter to contain more than one channel. A single channel SCSI adapter cannot be replaced by a dual channel adapter, even if the additional channels on the adapter are identical to the original SCSI adapter. If you add the replacement adapter to the system, you must configure the appropriate driver for that adapter in the kernel before beginning the replacement operation.
Installing the A6828A or A6829A Adapter Verifying Installation Verifying Installation This section includes information on verifying the installation of the A6828A and A6829A adapters.
Installing the A6828A or A6829A Adapter Verifying Installation TIP When the system boots after installation, the insf command creates the proper device files for the ctl interfaces (which are usually adapters) and the SCSI devices attached to the A6828A or A6829A adapter. Sometimes, though, it does not create all of the needed device files. One situation when this happens is when you attach SCSI disks to the adapter after the system boots and the adapter is already installed in the system.
Installing the A6828A or A6829A Adapter Additional Information Additional Information In addition to installing the adapter, you may want to perform the following tasks: • Review the recommendations for performance. • Determine what you need to do (if anything) to configure auto termination for the adapter. Change the jumper position, if needed. • Attach any external SCSI device you want to connect to the adapter.
