Cannot Confirm the Library or MO Jukebox Connection (Windows NT) Note The NT discovery process is not dynamic. When SCSI devices are powered on after the host, the control panel will not display their connection until the host is re-booted. 1. Confirm the library or MO jukebox connection by using the control panel menu on the server to review the SCSI device folder. 2. Before powering-on the bridge, make sure the library or MO jukebox and drives are configured for SCSI. This can be done through the front panel of the library or jukebox. 3. Make sure the libraries or MO jukebox, bridge, and switch are poweredon and connected appropriately before powering on hosts. If they were not connected, powered on, and configured properly before the host was powered-on, restart the host (and any other on the loop, one at a time). 4. If the host does not display the SCSI devices under the Fibre Channel HBA in the control panel, restart the host, and then recheck for the appearance of the library or MO jukebox SCSI devices. 5. Run the tape diagnostic utility from the host to verify that the library and drives are detected and pass all self-tests. 6. Verify SCSI bus configuration: Check all appropriate devices for the following conditions: - Termination: Problems with termination can cause intermittent or hard failure. - Terminate the SCSI bus on both ends, and only at the ends of the bus. By default, the bridge provides internal termination at the bridge end of each SCSI bus. Check each terminator and connector for bent pins. - Bus Type - The FC 4/1 HV bridge provides only HVD SCSI buses. SE or LVD SCSI devices cannot be supported on this bridge. Verify that all devices hooked up to each bus of the FC 4/1 HV are HVD SCSI devices. - The FC 2/1 LV bridge provides only LVD/SE SCSI buses. HVD SCSI devices cannot be supported on this bridge. Verify that all devices hooked up to each bus of the FC 2/1 LV are LVD or SE devices. Do not mix LVD and SE devices on the same SCSI bus of the FC 2/1 LV. 192 Diagnosing Problems Chapter 8
