5.6 iSCSI Target Page. By using the iSCSI Target page, the user can modify the “IP
Address”, “Subnet Mask”, “Gateway”, “iSCSI Name Prefix”, “iSCSI Protocol
Port”, “Max Connections” and “Authentication Method” settings for the iSCSI
Target on the Bridge. By default, the iSCSI Bridge’s connection type is set to
Static, i.e. the IP Address and Subnet Mask are permanent, as shown in the screen
capture below. If you have a DHCP server on your network connected to the
iSCSI Bridge and wish for the Bridge to “Obtain IP Automatically”, simply click
“Yes” at the label. By default the “iSCSI Name Prefix” is “iqn:1995-
10.com.paralan-:”. Note that “iSCSI Name
Prefix” is how the iSCSI Bridge will be seen by your iSCSI Initiator. For
example, if you have a SCSI target ID 3 connected to the iSCSI Bridge, your
iSCSI Initiator would identify this target during discovery as “iqn:1995-
10.com.paralan-:3”. The “Max Connections” field
is used to specify multiple iSCSI Initiator connections to the iSCSI Bridge.
5.6.1 CHAP (Challenge-Handshake Authentication Protocol). The iS5xx Series
Bridges have the ability to set CHAP usernames and secrets. One-Way
(Targets must authenticate the Initiators) and Mutual CHAP (Targets and
Initiators must independently authenticate one another) are supported.
Once authentication has been made and communications are established,
normal operations between the two authenticating devices can happen,
thus the overall system overhead is not affected. The iS5xx iSCSI Series
Bridges are initially provided with CHAP turned off.
