Installing the A6828A Adapter Chapter 2 8 • “P erformance Tuning” on page 11 • “Preparing for Installation” on page 12 • “Installing the A6828A Adapter” on page 13 • “Connecting .
Installing the A6828A Adapter Overview of Installation Steps Chapter 2 9 Overview of Installation Steps Here is a high-level view of the steps for installing the A6828A HBA: Step 1. Review the recommendations for performance (see “Performance Tuning” on page 11).
Installing the A6828A Adapter Overview of Installation Steps Chapter 2 10 Step 8. If you will be using a disk array in a multi-host environment, ensure that you have a LUN 0 configured (see “Configuring LUN 0” on page 52). Step 9. V erify the installation (see “V erifying Installation” on page 55).
Installing the A6828A Adapter P erformance T uning Chapter 2 11 P erformance Tuning T o get the best performance from the A6828A adapter , HP recommends the following things: • Increase the number specified for the scsi_max_qdepth kernel tunable parameter: — HP-UX 11.
Installing the A6828A Adapter Preparing for Installation Chapter 2 12 Preparing for Installation Installation of the A6828A adapter requires disassembly of some system components . Before beginning the installation, see the HP-UX system’s manual for detailed instructions about installing host bus adapters in the PCI slots.
Installing the A6828A Adapter Installing the A6828A Adapter Chapter 2 13 Installing the A6828A Adapter This section contains information on installing the A6828A HBA in an HP-UX system (including Online Addition and Replacement [OLAR]).
Installing the A6828A Adapter Installing the A6828A Adapter Chapter 2 14 NO TE As stated earlier , although the A6828A HBA 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.
Installing the A6828A Adapter Installing the A6828A Adapter Chapter 2 15 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.
Installing the A6828A Adapter Installing the A6828A Adapter Chapter 2 16 During an adapter replacement operation, SAM performs a Critical Resource Analysis ( CRA ), which checks all c hannels on the target adapter for critical resources that will be temporarily unavailable while the adapter is shut down.
Installing the A6828A Adapter Installing the A6828A Adapter Chapter 2 17 Adapter Compatibility This section explains adapter compatibility considerations for performing OLA and OLR. Online Addition (OLA) Y ou can add multiple adapters at the same time.
Installing the A6828A Adapter Installing the A6828A Adapter Chapter 2 18 The PCI specification allows 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 channel(s) on the adapter are identical to the original SCSI adapter .
Installing the A6828A Adapter Connecting External SCSI P eripherals Chapter 2 19 Connecting External SCSI P eripherals The A6828A adapter is capable of communicating with Low V oltage Differential (L VD) or Single Ended (SE) SCSI devices. L VD allows up to 12m cable lengths with multiple SCSI devices, or 25m point-to-point connections .
