Small Computer System Interface (SCSI) targets include disks, tapes, and other storage devices. These
targets do not register logical unit numbers (LUNs) with the name server.

•
The SCSI LUN discovery feature uses the local domain controller Fibre Channel address. It uses the
local domain controller as the source FC ID, and performs SCSI INQUIRY, REPORT LUNS, and READ
CAPACITY commands on SCSI devices
The SCSI LUN discovery feature is initiated on demand, through CLI or SNMP. This information is also
synchronized with neighboring switches, if those switches belong to the Cisco MDS 9000 Family.
