Cabling may be too long, too many devices connected, no bus termination, non-shielded internal cables being used for external applications, badly seated connectors, tape drive has same SCSI ID as another device etc. 2. Tape Drive not switched on, or faulty. 3. HBA faulty. 4. HBA Driver not loaded, or incorrect driver loaded. 5. Tape Device driver or ASPI driver not loaded, or incorrect driver loaded. 6. Tape Device driver does not support tape drive. HP SureStore DAT and DLT drives have wide tape device driver connectivity - see the answer to the question "What HP SureStore DAT and DLT tape drives are certified by Microsoft, ISV's and IHV's for use on Windows NT?" for full details. 7. Backup Application does not support tape drive - HP SureStore DAT and DLT drives have wide backup application connectivity - see the answer to the question "What HP SureStore DAT and DLT tape drives are certified by Microsoft, ISV's and IHV's for use on Windows NT?" for full details. In our experience, faulty tape drives and HBAs are unlikely to be the cause of the problem, so all other possibilities should be checked first. checking the cables The simplest way to check that the cabling is not at fault is to look for the SCSI Inquiry string of the Tape Drive, which should be displayed by the SCSI HBA BIOS (of the HBA to which the drive is attached) when the system is booting. If the SCSI Inquiry string of the tape drive is seen at boot time, then it is unlikely that the problem is one of the first three listed above. However, this will not preclude any SCSI errors which arise from marginal cabling, and which generally show up during high-speed synchronous data transfer (when performing backups/restores). Some systems will not display the SCSI Inquiry strings when booting. However all Adaptec and Symbios SCSI controllers with a BIOS should do this. checking the HBA driver In order to check that HBA and Tape drivers are working correctly, use the method described in the answer to the question "How do I know what drivers I am using at the moment, and what drivers do I need for running tape backups?". Note, however, that this method cannot be used for tape drivers for applications, such as ArcServe, which do not use the standard Windows NT Tape Driver architecture. In the Windows NT 4.0 Tape Devices applet, if the tape driver is displayed, but not shown as loaded, then it is likely that the driver does not support the device. See the answer to the question "How do I know what drivers I am using at the moment, and what drivers do I need for running tape backups?" for which tape drives are supported by Windows NT out-of-the-box. If using ISV Backup Software, consult the particular Backup Software's documentation to find out which tape drives are supported by the ISV's drivers. how to get further information In order to check that the Backup Application supports the tape drive, check with the ISV, or check "http://www.hp.com/go/connect". next question Go to the next question "Are there any important points I need to be aware of when changing drivers in my system?" © 1999-2001, Hewlett-Packard Company file:///C|/Documents%20and%20Settings/topher.COL-SPRINGS/Desktop/dltvs80%20manual/document/common/drivers_faqs/eng/nt_q3.htm [11/29/2001 8:35:50 AM]
