Modifying the properties of an iSCSI target

You can modify the properties of an iSCSI target in the NAS Manager.

1. Navigate to Home > File Services > iSCSI Targets to display the iSCSI Targets page.
2. Select the check box next to the target to modify and then click details.

   The following table describes the fields on this page:

   Field/Item	Description
   EVS	Selector for EVS where LUs reside.
   EVS iSCSI Domain	Displays the iSCSI Domain, which is the DNS domain used when creating unique qualified names for iSCSI Targets.
   Alias	Name of the iSCSI Target.
   Regenerate GUN	Click to regenerate the Globally Unique Name (GUN).
   Comment	Additional information about the iSCSI Target.
   Secret	Password used to secure the Target from any unauthorized access. The initiator authenticates against this password when connecting to the Target. The secret should be greater than or equal to 12 characters, but less than 17 characters, in length. Although the secret may be between 1-255 characters in length, some iSCSI initiators will refuse to connect if the secret contains less than 12 characters or more than 16 characters.
   Enable Authentication	Enable authentication of the iSCSI Target. By default, the check box is not filled. Filling or clearing the check box enables or disables authentication. When authentication is disabled, initiators are permitted to connect to the target and its LUs without needing to know the target's secret.
   Access Configuration	The access configuration parameters.
   Available logical units	The list of LUs available for assignment to the iSCSI Target. This list includes all LUs on the EVS. Some of these LUs may already be assigned to other targets.
   Selected LUN - LUN Name	The list of LUs selected to be part(s) of the iSCSI Target.
   Logical Unit Number	The number assigned to the LU (the LUN). Enter a Logical Unit Number in the range of 0-255.

3. The iSCSI Domain, Alias, Available LUs, and Logical Unit Numbers are required. Optionally, you can specify the Comment, Secret, and/or Access Configuration for the Target.
   Note: Once set, the iSCSI Domain cannot be changed, but it will be overridden/replaced if you later specify a new iSCSI Target with a different iSCSI Domain in the same EVS. The most recently specified iSCSI Domain overrides all previously-specified iSCSI Domains set for all previously added iSCSI Targets in the EVS.

   The following table describes what you can type in the Access Configuration field.

   What to type	Means
   Blank or *	All clients can access the target.
   Specific address or name. Examples: 10.168.20.2, client.dept.company.com To deny access to a specific host, use the no_access or noaccess qualifier. For example, 10.1.2.38 (no_access) will deny access to the host with the IP address 10.1.2.38.	Only clients with the specified names or addresses can access the target.
   Partial address or name using wildcards. Examples: 10.168.*.*, *.company.com To deny access to a specific host, use the no_access or noaccess qualifier. For example, 10.1.2.38(no_access) will deny access to the host with the IP address 10.1.2.38.	Clients with matching names or addresses can access the target.
