CHAP Initiator Settings

Last modified
Table of contents

The ‘CHAP Initiator Settings’ page allows you to define the Challenge-Handshake Authentication Protocol (CHAP) credentials that your appliance should expect from initiators that are attempting to access volumes.  An example of the CHAP initiator settings page is shown below.




To add a record, click the ‘Add New Record’ button found at the bottom of the table.  The display will change to edit mode, where you can type in values in the ‘Initiator Username’ and ‘Initiator Secret’ fields.  These values should align with the username and secret (password) fields that you supply on your server iSCSI initiator software.  The edit mode is displayed below.




When you have finished creating the entry, click the green checkmark  on the left side of the row to save your changes, or click the red X  on the left side of the row to discard your changes.  Initiator secrets (passwords) must be at least 12 characters in length.  Initiator usernames should be all lower case.  Note that some operating systems may have restrictions on the maximum length of initiator secrets (passwords).  For instance, Microsoft Windows Server 2008 only supports secrets of up to 16 characters.


To edit an existing initiator’s username or secret, click the ‘Edit’ icon, which appears as a pencil , on the far left of the row containing the initiator’s configuration.  Similar to the process used when creating a CHAP initiator as described above, a green checkmark icon  will appear at the left end of the row, which can be used to save your changes.  A red X  will also appear at the left end of the row, which can be used to cancel your changes.


If you wish to delete a configured CHAP initiator, click the red X icon  to the left of the initiator username while not in the edit mode.  Your appliance will prompt you for confirmation using a pop-up window, to ensure that you really wish to delete the CHAP initiator entry.
