3.Select the Wizard’s Search for Better Driver option and specify the folder containing the interface card INF file. The Hardware Wizard will scan the specified folder for all INF files and will select the first INF file it finds with a device entry containing a matching hardware ID string.

NOTE: The Hardware Wizard will copy the selected INF file, renaming it to OEM<#>.inf, where the # is some integer, and it will place the copied file into the C:\WINNT\inf folder. The Hardware Wizard will then compile the INF file to a .PNF file with the same root filename and use its interface card model entry information to install, or register, the newly discovered device.

4.Reboot the host PC to complete the process, as prompted by the Hardware Wizard.

Verify SCSI bus configuration

Problems with SCSI bus configuration are common. Basic operation of a SCSI bus can be checked by using the configuration menu to view attached SCSI devices.

Other conditions to look for include:

Termination—Problems with termination can cause intermittent or hard failure. A SCSI bus must be terminated on both ends, and only both ends. Termination issues when both narrow and wide devices are on the same bus are common. Check to make sure that there are no loose terminators. All terminators should be firmly attached.

Bus Type—The SE and LVD devices can be connected to the same SCSI bus; however, on power-up, if at least one SE device is detected, the LVD devices must convert to SE mode, and SE mode will be used. Only the LVD interface is being specified for the Fast/40 and higher rates.

Device ID—Each device on a SCSI bus must have a unique ID. Also check the configured ID’s for the interface card to verify these are not in use by other devices on the same SCSI bus.

Cabling—Check SCSI cables to verify that they are functional. SCSI rules for total length, distance between devices, and stub length must be adhered to. Connections should also be checked and reseated if necessary. Ensure that the SCSI cables are Multimode or rated for the SCSI speed of the drive.

SCSI Devices—Verify that the SCSI devices on a particular SCSI bus can be seen in the configuration menu of the interface card. Select System Utilities > System Statistics > Parallel SCSI Protocol Status > Display Attached SCSI Devices > Display ALL Local Devices. If the interface card can not see the devices, verify SCSI configuration, cabling, and termination.

Even if the SCSI devices are displayed, they are not accessible unless the mapping mode is auto-assigned or another non-empty map is used.

Verify Fibre Channel connection

If SCSI devices are recognized on the SCSI buses, but do not appear to the Fibre Channel host, it may be that the Fibre Channel link is not properly established. Most hubs and switches have link indicators, showing link status. When the interface card is connected and the library is powered-on, this link indicator should show a good link (see Operation indicators” on page 10). If it does not, check the cabling and connections.

As a means of verifying link integrity when connected to a functional host, disconnecting then reconnecting the Fibre Channel cable should cause momentary activity of this indicator as the link itself reinitializes. Also verify that the media type of the interface card and attached hub, HBA, or switch are of corresponding types. When using optical media, verify that the attached device is using non-OFC type optical devices.

Also, make sure that the interface card is configured with the same speed as the device it is connected to, and that the host is assigned to a LUN map filled with the devices it should be able to communicate with.

Verify SCSI devices in Windows NT

If running FC-to-SCSI mapping mode, open the NT Control Panel, select SCSI Adapters, and double click on the FC HBA. The SCSI devices should be listed.

If no devices are listed, verify the interface card configuration, FC HBA configuration, and cabling.
