114 Addressing, structures, and operations
The network storage router supports the Peripheral Device Addressing Method and the Logical Unit
Addressing Method, depending on the configuration.
Table 20 Arbitrated Loop Node number to AL_PA lookup table
The data shown in Table 20 comes from the Fibre Channel Configuration Menu (setting the AL_PA value)
on the network storage router. The user enters the node number (number to the left of the colon from
Table 20) and the network storage router translates the node number into the corresponding AL_PA value
(number to the right of the colon in Table 20).
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 FCP LUN values are filled with adjacent FCP
LUNs referencing each subsequent SCSI device. The host system will then detect every attached SCSI
device without voids, allowing full device discovery to the host. This allows easy configuration in
environments where SCSI device ordering is not important, and where hot plugging of SCSI devices will
not occur. Configuration options provide for the SCSI discovery to be performed in order of bus, target, or
LUN as desired for the specific environment.
