You install a SCSI 2 Ultra host adapter with 4 drives. After you bring up the system you notice that only 2 drives are detected. What is :the likely cause for this problem?
The hard drives have been configured with the same SCSI ID
Each device on a SCSI bus has to have its own unique SCSI ID or device conflicts will occur. The host adapter should be set to ID 7 and the boot device should be 0. Any mismatch in this configuration will lead to devices not being recognized.
