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:
