SCSI Standard Devices are not recognized Type of Failure: SCSI Devices attached to the SCSI bus are not correct recognized. Cause: Every SCSI unit attached to the SCSI bus requires a unique SCSI ID. No ID must be used twice. If to devices use the same ID, only one of them will be recognized. In some cases none of them may show up on the SCSI bus. The SCSI controller itself uses ID 7, so no attached unit is allowed to use ID 7. Solution: Check the SCSI IDs of your SCSI devices according to the respective documentation. If neccessary, correct the drive ID settings.
