ATTO Technology 1500D/E, 1550D/E operation manual Example, To remove an iSCSITarget

Page 55

To manually configure MultiTargetMode 1 At the CLI prompt type

set MultiTargetMode enabled

Because current mapping will be deleted, you are asked for confirmation to change mapping.

2Type SCSITargets to list the SCSI devices connected to the SCSI port.

The SCSITargets 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.

3The command iSCSITarget creates each iSCSI Target node. Type

iSCSITarget [name]

The name is a suffix appended to the standard IPBridge iqn name. The suffix name can be up to 24 characters.

4Type RouteDisplay to see the results of the iSCSITarget command.

5The Route command performs the mapping. Type

Route iSCSI <Target Name> <lun> SCSI <sb> <st> <sl>

•Target Name corresponds to the Target Name created with the iSCSITarget command.

•lun is the iSCSI LUN the SCSI device is to be mapped to

•sb is the SCSI bus/port on the iPBridge the device is connected to

•st and sl are the SCSI target ID and SCSI LUN that the SCSI device is currently configured for.

To map the first tape device listed in the scsitargets command in Exhibit 2.3-3,type

route iscsi tape0 scsi 0 4 0

To remove mapping

1 Type:

Route iSCSI [Target Name] [lun] delete

To remove an iSCSITarget

1 Type

iSCSITarget [Target Name] delete

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.

Exhibit 2.3-2 Result of typing SCSITargets 0

The iPBridge occupies iSCSI LUN 0 by default,

In multiple target mode, the media changer is mapped differently in each node: at iSCSI LUN 3 in node 0 and at iSCSI LUN 1 in node 1.
