DuraStor 412R/6320SS/7320SS Installation and User's Guide Host SCSI Channel Problems Symptom The host SCSI BIOS scan displays "Device name not available." The host SCSI BIOS scan hangs. Only one array is displayed during host SCSI BIOS scan. All arrays are displayed during host SCSI BIOS scan, but only one array is seen by the operating system. Solution The controller is properly installed, but no arrays have been created. Use Disk Array Administrator to create an array and reboot the host system. Check that termination is set correctly in the Configuration Menu and the drive enclosure. Check that the device ID set in the software does not conflict with any other devices on the host SCSI channel. If you have a long SCSI cable, try a different or shorter cable. Check to ensure that LUN support is enabled. Most SCSI host adapters ship with LUN support disabled by default. Check the LUN assignment for each array. If LUN 0 is not assigned to an array, or some other LUN numbers are skipped, change the LUN assignments for each array until you have LUN numbers starting at 0 with no LUNs skipped. You must reboot the host system to recognize the new LUN assignment. SCSI drivers for some operating systems require a parameter switch to enable LUN support. Check the driver documentation for your host SCSI channel. You may also need to compact the LUN mapping. 6-8
