Many manufacturers provide utilities and hardware features to simplify HBA installation. For example, Emulex AutoPilot software allows administrators to install multiple HBAs simultaneously and remotely in as few as six mouse clicks. Other vendors, such at ATTO Technology, LSI Logic and Qlogic, also offer aids in getting your new HBAs running. Availability varies from manufacturer to manufacturer. It's important to check and see what your HBA offers.

Make sure you have the latest firmware |

|
|
|

|
|
|
Check the installed firmware against the latest version available on the manufacturer's Web site. If you don't have the newest applicable version, download and install the newer firmware. |

Bringing up an HBA is a multi-step process. The temptation is to blast through it. Don't. Check your progress at each step by testing what you have done so far. For example, once you have installed the card and the drivers, check to make sure that your system recognizes the HBA. (In Windows 2000, you can do this by looking at Windows Device Manager. If the HBA is correctly installed, it should appear under the SCSI and RAID controllers, not the network devices.) |

Probably 90% of the problems with HBAs come from the connections. Make sure the card is properly seated in the chassis and that all the cable connections are correct and tight. It often helps to give the socket with a blast of canned air to get any dust out before you seat the card.

Know yellow from orange and ST from SC

Single mode fiber cable has a yellow coating. Multimode (short wave) cable is orange. Using the wrong kind of cable will damage or destroy your device. The consequences of having the wrong kind of connectors on your cables are less drastic, but still won't work. ST is the coming thing in FC SANS, but SC is still common.

Configure your switch and fabric |

If your switch and fabric are not set to handle the new HBA you can waste a lot of time trying to troubleshoot an "HBA problem," which is actually elsewhere. Your RAID controller needs to be set up correctly, for example. If your SAN supports zoning make sure the HBA is included in the appropriate zone. Likewise, set your HBA for the speed of your target device.
