Assigning SCSI Device IDs
Assigning SCSI Device IDs
Before assigning a SCSI device ID to your drive, you need to check your existing SCSI device IDs. To determine which SCSI device IDs are available for your device, use the ioscan command in a terminal window:
1At a command line prompt, enter the following:
/usr/sbin/ioscan
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:
