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