enable ddset
command with the
-n
option to enable the DDSet:

iSCSI initiator-to-VT authentication configuration
Fabric OS v6.1.0 or later supports both one-way and mutual CHAP authentication for iSCSI
initiator-to-iSCSI VT target sessions. The authentication method (CHAP or none) is set on a
per-iSCSI VT basis.
Setting the user name and shared secret
Authentication depends on a user name and shared secret. When an iSCSI VT authenticates an
iSCSI initiator, it checks the user name and shared secret against all configured CHAP values. To
enforce authentication of iSCSI initiators, set each iSCSI VT authentication to CHAP. The iSCSI
initiator can use any user name and shared secret for any iSCSI VT configured on the fabric.
1.
Connect and log in to the switch.
2.
Enter the
iscsiCfg
--
create auth
command with the
-u
and
-s
options to configure a user name
and shared secret:
switch:admin>
iscsicfg --create auth -u username0001 -s usersecret0001
The operation completed successfully.
3.
Enter the
iscsiCfg
--
modify tgt
command with the

options to set CHAP as the
authentication method:
switch:admin>
iscsicfg --modify tgt -t iqn.2006-10.com.brocade:example-disk001

The operation completed successfully.
4.
To verify that CHAP is enabled for the iSCSI VT, enter the
iscsiCfg
--
show tgt

Binding user names to an iSCSI VT
For additional security, you can bind specific user names to an iSCSI VT. When you do this, the
specific user name and CHAP secret combination is required for authentication during the iSCSI
login phase. The maximum number of user names that can be bound per iSCSI VT is 16.
