You can use ONTAP System Manager classic (available in ONTAP 9.7 and earlier) to configure the iSCSI protocol that enables you to transfer block data to hosts using SCSI protocol over TCP/IP.

Create iSCSI aliases

An iSCSI alias is a user-friendly identifier that you assign to an iSCSI target device (in this case, the storage system) to make it easier to identify the target device in user interfaces. You can use System Manager to create an iSCSI alias.

About this task

An iSCSI alias is a string of 1 to 128 printable characters.An iSCSI alias must not include spaces.

Steps

  1. Click Storage > SVMs.

  2. Select the SVM, and then click SVM Settings.

  3. In the Protocols pane, click iSCSI.

  4. In the Service tab of the iSCSI window, click Edit.

  5. In the Edit iSCSI Service Configuration dialog box, enter an iSCSI alias in the Target Alias field, and then click OK.

Enable or disable the iSCSI service on storage system interfaces

You can use System Manager to control which network interfaces are used for iSCSI communication by enabling or disabling the interfaces. When the iSCSI service is enabled, iSCSI connections and requests are accepted over those network interfaces that are enabled for iSCSI, but not over disabled interfaces.

Before you begin

You must have terminated any outstanding iSCSI connections and sessions that are currently using the interface. By default, the iSCSI service is enabled on all of the Ethernet interfaces after you enable the iSCSI license.

Steps

  1. Click Storage > SVMs.

  2. Select the SVM, and then click SVM Settings.

  3. In the Protocols pane, click iSCSI.

  4. In the iSCSI Interfaces area, select the interface on which you want to enable or disable the iSCSI service.

  5. Click Enable or Disable, as required.

Add the security method for iSCSI initiators

You can use System Manager to add an initiator and to specify the security method that is used to authenticate the initiator.

Steps

  1. Click Storage > SVMs.

  2. Select the SVM, and then click SVM Settings.

  3. In the Protocols pane, click iSCSI.

  4. In the iSCSI window, click the Initiator Security tab.

  5. Click Add in the Initiator Security area.

  6. Specify the initiator name and the security method for authenticating the initiator.

    For CHAP authentication, you must provide the user name and password, and then confirm your password for inbound settings. For outbound settings, this login information is optional.

  7. Click OK.

Edit default security settings

You can use the Edit Default Security dialog box in System Manager to edit the default security settings for the iSCSI initiators that are connected to the storage system.

Steps

  1. Click Storage > SVMs.

  2. Select the SVM, and then click SVM Settings.

  3. In the Protocols pane, click iSCSI.

  4. In the Default Security area of the Initiator Security tab, click Edit.

  5. In the Edit Default Security dialog box, change the security type.

    For CHAP authentication, you must provide the user name and password, and then confirm your password for inbound settings. For outbound settings, this login information is optional.

  6. Click OK.

Change the default iSCSI initiator authentication method

You can use System Manager to change the default iSCSI authentication method, which is the authentication method that is used for any initiator that is not configured with a specific authentication method.

Steps

  1. Click Storage > SVMs.

  2. Select the SVM, and then click SVM Settings.

  3. In the Protocols pane, click iSCSI.

  4. In the Initiator Security tab, click Edit in the Default Security area.

  5. Change the security type.

    For CHAP authentication, you must provide the user name and password, and then confirm your password for inbound settings. For outbound settings, this login information is optional.

  6. Click OK.

Set the default security for iSCSI initiators

You can use System Manager to remove the authentication settings for an initiator and to use the default security method to authenticate the initiator.

Steps

  1. Click Storage > SVMs.

  2. Select the SVM, and then click SVM Settings.

  3. In the Protocols pane, click iSCSI.

  4. In the Initiator Security tab, select the initiator for which you want to change the security setting.

  5. Click Set Default in the Initiator Security area, and then click Set Default in the confirmation dialog box.

Start or stop the iSCSI service

You can use System Manager to start or stop the iSCSI service on your storage system.

Steps

  1. Click Storage > SVMs.

  2. Select the SVM, and then click SVM Settings.

  3. In the Protocols pane, click iSCSI.

  4. Click Start or Stop, as required.

View initiator security information

You can use System Manager to view the default authentication information and all the initiator-specific authentication information.

Steps

  1. Click Storage > SVMs.

  2. Select the SVM, and then click SVM Settings.

  3. In the Protocols pane, click iSCSI.

  4. In the Initiator Security tab of the iSCSI window, review the details.

iSCSI window

You can use the iSCSI window to start or stop the iSCSI service, change a storage system iSCSI node name, and create or change the iSCSI alias of a storage system. You can also add or change the initiator security setting for an iSCSI initiator that is connected to your storage system.

Tabs

  • Service

    You can use the Service tab to start or stop the iSCSI service, change a storage system iSCSI node name, and create or change the iSCSI alias of a storage system.

  • Initiator Security

    You can use the Initiator Security tab to add or change the initiator security setting for an iSCSI initiator that is connected to your storage system.

Command buttons

  • Edit

    Opens Edit iSCSI Service Configurations dialog box, which enables you to change iSCSI node name and iSCSI alias of the storage system.

  • Start

    Starts the iSCSI service.

  • Stop

    Stops the iSCSI service.

  • Refresh

    Updates the information in the window.

Details area

The details area displays information about the status of the iSCSI service, iSCSI target node name, and iSCSI target alias. You can use this area to enable or disable the iSCSI service on a network interface.
