RouteXXX family
If you have not enabled AddressMap C, you may
use CLI commands to find all the SCSI devices on
SCSI busses. With this information you then
decide where you want to place these devices on
the Fibre Channel ports.
You can then manually map the devices using the
RouteXXX family of commands or the
AutoMap
command (see Chapter 4.1.8) available through
the Command Line Interface or the menu or by
using ATTO BridgeTools (see Chapter 4 and
Chapter 3.1).
RouteDisplay
displays the current mapping, if
AddressMap C has not been enabled, in Fibre
port, Fibre LUN order, showing the mapped SCSI
bus/target/LUN, and the current status of the
device (online, offline, disabled, mapped,
unmapped). RouteDisplay may be used at any
time.
RouteOffline, RouteChange, and RouteOnline
modify the mapping as required to make a device
inaccessible, to replace a non-functioning mapped
unit with another or to manage wear on tape
drives. The commands will not modify a port
being used as a failover port in AddressMap B
mode.
In the chart at right, the SCSI device on SCSI bus
0 at SCSI address of ID 0 LUN 0 is being mapped
to Fibre Port 0 (on the FibreBridge) at Fibre
Channel LUN 4.
Note: two SCSI devices cannot be mapped to the same
Fibre Port and Fibre Channel LUN. Also, if the same
SCSI device is mapped to two different Fibre Port
and/or Fibre Channel LUNs, these Fibre Port and
Fibre Channel LUNs will be taken offline
automatically until the conflict is resolved.
The
BootScan
command
(see Chapter 4.1.8),
available through the Command Line Interface,
ATTO BridgeTools or the menu (see Chapter 3.1
and Chapter 4), provides dynamic mapping of
SCSI devices to Fibre port/LUN combinations via
a SCSI bus scan at boot time. Each time the
FibreBridge is reset or power-cycled and
BootScan is enabled, a bus scan will occur on all
SCSI busses. All devices discovered during the
bus scans will be assigned to a Fibre port, Fibre
LUN combination until the next reset/power
cycle. The dynamic mapping will replace the
current mapping of the FibreBridge.
