are asked for confirmation to change mapping.
SCSITargets
2
Type
to list the SCSI devices
connected to the SCSI port.
SCSITargets
The
command lists each device
and its corresponding SCSI address. In the
example in Exhibit 2.3-2, the first tape drive is
on SCSI Port 0 (on the IPBridge) at Target ID 4,
LUN 0.
iSCSITarget
3
The command
Target node. Type
iSCSITarget [name]
The name is a suffix appended to the standard

Example
Refer to Exhibit 2.3-1. A SCSI library containing
a media changer and four tapes is connected to the
IPBridge through SCSI port 0.
In single target mode, the media changer is at 0, 0,
1 (port, target and LUN) and each of the tapes is
at a different LUN.
