Assigning SCSI Device IDs
Assigning SCSI Device IDs
Before assigning a SCSI device ID to a new SCSI device, you need to determine which
SCSI device IDs are available. To view the SCSI IDs already in use, type the following
command at the prompt and press [Enter]:
/usr/sbin/ioscan -f
After a few moments, the ioscan utility lists all of the I/O devices it could find. The list
appears similar to the following:

Assigning External SCSI Device IDs
You can determine which SCSI devices are currently in use by looking under the H/W Path
heading in the output from the ioscan command. The entry 10/0/15/0 is the built-in SCSI
bus. For devices connected to the built-in 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 an SCSI device at SCSI ID
