Assigning Ultra2 Wide Low-Voltage Differential SCSI Device IDs
You can determine which Ultra2 Wide Low-Voltage Differential SCSI (LVD SCSI) devices are currently in use by reviewing the output from the ioscan command discussed above and looking under the “H/W Path” heading. The entry 10/0/15/1 is the built-in Ultra2 Wide Low-Voltage Differential SCSI bus. For devices connected to the built-in Ultra2 Wide Low-Voltage Differential SCSI bus, such as disks, the number between the two decimals and after the third “/” in the hardware path specifies the SCSI ID for that device. For example, a hardware path of 10/0/15/1.5.0 specifies a LVD SCSI device at SCSI ID 5. Here is the break down of the hardware path:
| SCSI device | 10/0/15/1.5.0 |
| LVD SCSI | 10/0/15/1.5.0 |
| SCSI ID 5 | 10/0/15/1.5.0 |
| Do not use SCSI device ID 7 for any device. It is reserved for the built-in |
CAUTION |
| SCSI bus controller. |
