iSNS Login Control cannot be used with
Access Control found on the iSCSI Target
Management page.
iSNSServer
Specifies whether the IP address of a valid iSNS server
from which the iPBridge will attempt iSCSI initiator
discovery. Setting to 0.0.0.0 disables the iSNS server
lookup. Default is 0.0.0.0.
SpeedWrite

commands to SCSI devices attached to the iPBridge.

CHAP commands

To find the CHAP commands,
1 Click on the Manual Target Mgt menu item
2 Click on the Target Management page
3 Click on the iSCSI CHAP table entry next to the
iSCSI target you wish to use.
iSCSI CHAP
iSCSI CHAP controls whether CHAP (Challenge
Handshake Authentication Protocol) is used for the iSCSI
protocol. If CHAP is enabled, the target requires the
initiator to negotiate CHAP authentication using CHAP
secrets (passwords). An initiator may reject this
negotiation.
iSCSI Chap Secret
Specifies the incoming and outgoing secrets (passwords)
for iSCSI CHAP sessions. Secrets are case sensitive, 12
to 32 characters (16 for Microsoft iSCSI initiator), and
cannot contain spaces. In and out secrets must be
different.
An in secret is for authentication of the server to the
iPBridge. The iPBridge can store up to 32 in secrets.
An out secret is for authentication of the iPBridge to the
server. There is only one out secret per target that cannot
be deleted.
iSCSI Target
Creates or deletes an iSCSI target name. The target
name acts as a suffix to the standard bridge iSCSI-
qualified name. The target name may not exceed 24
characters.
