Entering mutual authentication permissions
Mutual authentication or two-way authentication is a way for a client or a user to verify themselves to a host server, and for the host
server to validate itself to the user. This validation is accomplished in such a way that both parties are sure of the other’s identity.
To add mutual authentication permissions:
1
In the AMW, select the
Setup
tab.
2
Select
Manage iSCSI Settings
.
The
Manage iSCSI Settings
window is displayed.
3
Select the
Remote Initiator Configuration
tab.
4
Select an initiator in the
Select an Initiator
area.
The initiator details are displayed.
5
Click
CHAP Secret
to enter the initiator CHAP permissions in the dialog that is displayed.
6
Click
OK.
7
Click
OK
in the
Manage iSCSI Settings
window.
Creating CHAP secrets
When you set up an authentication method, you can choose to create a CHAP secret. The CHAP secret is a password that is recognized
by the initiator and the target. If you are using mutual authentication to configure the storage array, you must enter the same CHAP secret
that is defined in the host server iSCSI initiator, and you must define a CHAP secret on the target (the storage array) that must be
configured in every iSCSI initiator that connects to the target storage array. For more information about CHAP, see Understanding CHAP
Authentication in the storage array's Deployment Guide.
Initiator CHAP secret
The initiator CHAP secret is set on the host using the iSCSI initiator configuration program provided with the host operating system. If you
are using the mutual authentication method, you must define the initiator CHAP secret when you set up the host. This must be the same
CHAP secret that is defined for the target when defining mutual authentication settings.
Target CHAP secret
If you are using CHAP secrets, you must define the CHAP secret for the target.
Valid characters for CHAP secrets
The CHAP secret must be between 12 and 57 characters. The CHAP secret supports characters with ASCII values of 32-126 decimal. See
the following table for a list of valid ASCII characters.
