ATTO Technology Inc. iPBridge Installation and Operation Manual
3.1 Target management
Storage devices are mapped using the designations for the iSCSI LUN. The easiest way to map devices
is to use the Automatic Target Management feature in the ATTO ExpressNAV interface.
CAUTIONCAUTION
Changing the device map can affect the
host’s view of devices and your application
configuration.
To map SCSI devices, you must connect the
devices to the iPBridge SCSI port. To access
mapped SCSI devices over Ethernet, you must
have a host computer connected to the iPBridge
Ethernet data port.
If you decide to change the automatic mapping set
up when you powered up the iPBridge, you have
two options to map devices after you disable
automatic mapping:
• You may map devices manually to the single
default node.
• You may map each device to its own target,
breaking the single iSCSI target node into
multiple nodes. Multiple target nodes allow
flexibility to grant or deny access between
initiators and devices.
If you divide the default single target node into
multiple target nodes, you must set up access to
each node separately.
Targ et na mes
Each iSCSI target node is identified by a unique
world-wide iSCSI-qualified name which
references the iPBridge serial number and target
node name:
iqn.1995-12.com.attotech:ipbridge:
serialnumber <targetname>

Default target node

The default target is set as a single target with
Access Control (ACL) disabled and CHAP
authentication disabled. The default target node
cannot be deleted.
Use the ExpressNAV interface to map devices
automatically or manually. Refer to
Opening an
ExpressNAV session
on page 23 for information
