Configuring for SGI Irix
Finding Current |
| To properly attach SCSI devices to hosts it is necessary to ensure that each |
SCSI Controllers |
| target device has a unique SCSI address. The command hinv can be used |
and Targets |
| to find all attached SCSI controllers and target devices. To search for all |
|
| SCSI controllers and devices use the command: |
|
| hinv |
|
| The output of the command will be similar to the following: |
|
| Integral SCSI controller 0: Version ADAPTEC 7880 |
|
| Disk drive unit 1 on SCSI controller 0 |
|
| CD ROM unit 4 on SCSI controller 0 |
|
| Integral SCSI controller 1: Version ADAPTEC 7880 |
|
| Tape drive: unit 6 on SCSI controller 1: DAT |
|
| This output shows that a tape drive is present on SCSI controller 1 at SCSI |
|
| ID address #6. Available SCSI IDs are |
|
| • 0,2,3,5 6, 8 - 15 on controller 0 |
|
| • 1 - 5 and 8 - 15 on controller 1 (this controller supports Wide/Ultra SCSI) |
|
|
|
|
| Note: SCSI ID #7 is almost always dedicated to the SCSI controller. |
|
| Never configure your target device for ID 7 unless you are |
|
| absolutely sure that the controller is not addressed for ID 7. |
