Problems After Installation
There are three basic types of installation problems that can cause your QLA23xx HBA to function incorrectly: hardware problems, system configuration problems, and Fibre Channel problems. The following section provides itemized checklists to help you determine why your QLA23xx HBA is not functioning.
4.2
Hardware Problem Checklist
■Are all of the circuit cards installed securely in the system?
■Are all of the cables securely connected to the correct connectors? Be sure that the FC cables that attach from the QLA23xx HBA connectors to the device are connected correctly. For example, the optical transmit connector on the QLA23xx HBA must be connected to the optical receive connector on the device. Some connectors require a firm push to ensure proper seating. An easy way to check for correct seating is to switch the connectors on either the QLA23xx HBA or the device, then restart your system. If the BIOS is enabled, devices attached to the QLA23xx HBA are displayed on the screen.
■Is the QLA23xx HBA installed correctly in the PCI slot? Is it seated firmly in the slot?
■Check for interference due to nonstandard PCI connectors.
■Is the Fast!UTIL data rate setting correct? See the appropriate Fast!UTIL section for information about setting the data rate.
■Are all external peripherals properly powered up? See the appropriate Fast!UTIL section for information about displaying attached devices.
