Roger informs you that none of the three SCSI drives can be seen on his SCSI chain. What should you check?
- A.
Whether the host adapter is terminated and that the disks have consecutive IDs of 1, 2, and 3
- B.
Whether the SCSI adapter has an ID of 7 or 15, and whether all the disks are terminated and have consecutive IDs of 0, 1, and 2
- C.
Whether the host adapter has an ID of 0, and whether the disks are terminated with the same ID
- D.
Whether the SCSI adapter has an ID of 7, and whether both ends of the chain are terminated, and that each disk has a unique ID
Correct Answer
D. Whether the SCSI adapter has an ID of 7, and whether both ends of the chain are terminated, and that each disk has a unique IDExplanation
The correct answer suggests that the first thing to check is whether the SCSI adapter has an ID of 7. This is important because the SCSI adapter needs to have a specific ID in order to function properly. Additionally, it is important to ensure that both ends of the chain are terminated, as this helps to prevent signal reflections and ensure proper communication between devices. Lastly, each disk should have a unique ID, as having duplicate IDs can cause conflicts and prevent the drives from being recognized.Rate this question:
