UltraSCSI RAID Enclosure 4–5
Figure 4–4 Master Enclosure Device IDs
Use the PVA SCSI ID switch to establish SCSI bus IDs for all devices
in the enclosure. This switch has eight (0 through 7) positions.
Caution
To preclude SCSI bus addressing conflicts, Compaq only
supports PVA SCSI ID switch settings of 0, 2, and 3.
Always set the master enclosure PVA SCSI ID switch setting to 0.
