Auto Assigned Addressing Option Appendix B
Auto Assigned Addressing Option
The Auto Assigned option is similar to the Indexed addressing, but with the
distinction that the table used is created through SCSI device discovery on
power up or reset, and not otherwise retained. As the unit performs device
discovery on the SCSI bus, the Index table relating FCP LUN values is filled with
adjacent FCP LUNs referencing each subsequent SCSI device. The host
system will then detect every attached device without voids, allowing full device
discovery to the host. This allows easy configuration in environments where
device ordering is not important and hot plugging of SCSI devices will not occur.
Tape libraries are excellent candidates for using Auto Assigned Addressing.
Configuration allows for discovery to be performed in order of bus, target, or
LUN as desired for the specific environment.
