Managing iSCSI targets

Before you begin

Procedure

1. Click Storage Systems, and then expand the Storage Systems tree.

2. Click Ports/Host Groups/iSCSI Targets.

3. Enter the iSCSI alias in the iSCSI Target Alias box. If the Use Default Name checkbox is selected, the iSCSI target alias is input by default.

4. Enter the iSCSI target name in the iSCSI Target Name box. Select the format from iqn or eui. If the Use Default Name check box is selected, the iSCSI target name is input by default.

5. Select the resource group in which an iSCSI target is created. If you select Any, ports to which you can add iSCSI targets within all ports assigned to a user are displayed in the Available Ports list. If you select other than Any, ports to which you can add iSCSI targets within the ports assigned to the selected resource group are displayed in the Available Ports list.

6. Select a host mode from the Host Mode list. When selecting a host mode, you must consider the platform and some other factors.

7. If necessary, click Host Mode Options and select host mode options.

   When you click Host Mode Options, the dialog box expands to display the list of host mode options. The Mode No. column indicates option numbers. Select an option you want to specify and click Enable.

8. Select hosts to be registered in an iSCSI target. If the desired host has ever been connected with a cable to another port in the storage system, select the desired host bus adapter from the Available Hosts list. If there is no host to be registered, skip this step and move to the next step. Otherwise, an iSCSI target with no host would be created. If the desired host has never been connected through a cable to any port in the storage system, perform the following steps:

   1. Click Add New Host under the Available Hosts list. The Add New Host dialog box opens.

   2. Select the format from iqn or eui.

   3. Enter the desired HBA iSCSI name in the HBA iSCSI Name box.

   4. If necessary, enter a nickname for the host bus adapter in the Host Name box.

   5. Click OK to close the Add New Host dialog box.

   6. Select the desired host bus adapter from the Available Hosts list.

9. Select the port to which you want to add the iSCSI target. If you select multiple ports, you can add the same iSCSI target to multiple ports by one operation.

10. Select CHAP, None, or Comply with Host Setting in the Authentication Method list. If CHAP is selected, specify following:

    • Mutual CHAP: Select Enable or Disable. If Enable is selected, the mutual authentication mode is performed. If Disable is selected, the unidirectional authentication mode is performed.

    • User Name: If Disable is selected in Mutual CHAP, this item is optionally specified. If Enable is selected in Mutual CHAP, this item must be specified.

    • Secret and Re-enter Secret: If Disable is selected in Mutual CHAP, this item is optionally specified. If Enable is selected in Mutual CHAP, this item must be specified.

11. Select CHAP users to be registered in an iSCSI target. If the CHAP user has ever been connected with a cable to another port in the storage system, select the desired host bus adapter from the Available CHAP Users list. If there is no host to be registered, skip this step and move to the step 11. Otherwise, an iSCSI target with no CHAP user would be created. If the desired CHAP user has never been connected through a cable to any port in the storage system, perform the following steps:

    1. Click Add New CHAP User under the Available CHAP Users list. The Add New CHAP User dialog box opens.

    2. Specify an user name, and secret.

    3. Click OK to close the Add New CHAP User dialog box.

    4. Select the desired CHAP user from the Available CHAP Users list.

12. Click Add to add the iSCSI target. By repeating steps from 2 to 10, you can create multiple iSCSI targets. If you select a row and click Detail, the iSCSI Target Properties window appears. If you select a row and click Remove, a message appears asking whether you want to remove the selected row or rows. To remove the row, click OK.

13. Click Finish to display the Confirm window. To continue to add LUN paths, click Next.

14. Confirm the settings and enter the task name in the Task Name box. A task name can consist of up to 32 ASCII characters (letters, numerals, and symbols). Task names are case-sensitive. (date) - (task name) is input by default. If you select a row and click Detail, the iSCSI Target Properties window appears.

15. Click Apply in the Confirm window. If the Go to tasks window for status check box is selected, the Tasks window appears.
