2. Select an iSCSI port from the Subsystem Port Name. The IP address of the iSNS server appears in the
iSNS Server IP Address. Also, the port number of the iSNS server appears in the iSNS Server Port
Number.
3. Click OK. Information about the iSCSI port is removed from the iSNS server, and the iSCSI port is
unregistered from the iSNS server.
Checking the status of connection between hosts and the disk array
(iSCSI environment only)
In an iSCSI environment, use LUN Manager to issue a ping command from a disk array port to a host. The
ping command checks whether the host and disk array can communicate with each other. If the host
responds to the ping command, the host and disk array can communicate with each other.
Issuing a ping command from an iSCSI port to a host
1. Ensure that the Port tab is displayed in the pane.
2. Click Ping below the Package tree view. The Ping pane appears.
3. Select an iSCSI port from From (Subsystem Port).
4. Enter the IP address of the host in To (IP Address).
5. Click OK. A ping command is issued from the iSCSI port to the host five times. After the ping command
is issued five times, the Ping Result pane appears and displays the results in the order attempts were
made.
• If the host responded to the ping command, the Status column displays Success.
• If the host did not respond to the ping command, the Status column displays Error.
• The Success Rate field displays the success rate of the ping command. If the host responds to each
of the five ping attempts, the success rate is 100 percent. If the host responds three times out of five
ping attempts, the success rate is 60 percent.
6. Click OK to close the Ping Result pane.
7. To issue a ping command, return to step 3 . Otherwise, click Cancel to close the Ping window.
TIP: You can issue a ping command from an iSCSI port to an iSNS server. To verify connectivity between
an iSNS server and disk array, issue a ping command to the iSNS server. If the iSNS responds to the ping
command, the iSNS server and disk array can communicate with each other.
Setting user authentication (iSCSI environments only)
When configuring an iSCSI environment, you can use the User Authentication tab to set the user
authentication on disk array ports. First specify whether to perform authentication of hosts for each port.
Then register user information of hosts on the ports that perform authentication. This setting determines
whether ports can authenticate hosts that request to connect, and can restrict the connections. In addition,
if you want to implement mutual authentication, specify user information about each disk array port.
NOTE: The hosts to be connected must also be configured for authentication by ports (and for port
authentication by the host, if required). For details on how to configure the host for CHAP authentication,
refer to your operating system and iSCSI driver documentation.
Starting User Authentication Operations
NOTE: User authentication can be performed in an iSCSI environment only.
1. Click the LUN and Volume Mgmt tab, and then click the LUN Manager button ( ). The LUN Manager
main pane appears.
