SCSI connections assigning SCSI device IDs

assigning SCSI device IDs

Before assigning a SCSI device ID to your drive, you need to check the existing SCSI device IDs. To determine which SCSI device IDs are available for your device, use the ioscan command in a terminal window:

1. At a command line prompt, enter the following:

/usr/sbin/ioscan -f

After a few moments, the ioscan utility lists all of the SCSI I/O devices it could find. The list appears similar to the following:

SCSI connections assigning SCSI device IDs

assigning Ultra narrow single-ended SCSI device IDs

You can determine which Ultra Narrow Single-Ended SCSI (NSE 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 10/0/15/0 is the built-in Ultra Narrow

Single-Ended SCSI bus. For devices connected to the built-in Ultra Narrow Single-Ended

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

10/0/15/0.2.0

specifies a NSE SCSI device at SCSI ID 2.

Here is the break down of the hardware path:

SCSI device 10/0/15/ 0.2.0

NSE SCSI 10/0/15/ 0 .2.0

SCSI ID 2 10/0/15/0.

2 .0

CAUTION Do not use SCSI device ID 7 for any device. It is reserved for the built-in SCSI bus controller.

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

CAUTION Do not use SCSI device ID 7 for any device. It is reserved for the built-in SCSI bus controller.
