Configuring iSCSI devices

This section describes how to configure Internet Small Computer System Interface (iSCSI) devices when working under bootable media. After performing the steps below, you will be able to use these devices as if they were locally attached to the machine booted with bootable media.

An iSCSI target server (or target portal) is a server that hosts an iSCSI device. An iSCSI target is a component on the target server; this component shares the device and lists iSCSI initiators that are allowed access to the device. An iSCSI initiator is a component on a machine; this component provides interaction between the machine and an iSCSI target. When configuring access to an iSCSI device on a machine booted with bootable media, you need to specify the iSCSI target portal of the device and one of the iSCSI initiators listed in the target. If the target shares several devices, you will get access to all of them.

To add an iSCSI device in a Linux-based bootable media

  1. Click Tools > Configure iSCSI/NDAS devices.
  2. Click Add host.
  3. Specify the IP address and port of the iSCSI target portal, and the name of any iSCSI initiator that is allowed access to the device.
  4. If the host requires authentication, specify the user name and password for it.
  5. Click OK.
  6. Select the iSCSI target from the list, and then click Connect.
  7. If CHAP authentication is enabled in the iSCSI target settings, you will be prompted for credentials to access the iSCSI target. Specify the same user name and target secret as in the iSCSI target settings. Click OK.
  8. Click Close to close the window.

To add an iSCSI device in a PE-based bootable media

  1. Click Tools > Run the iSCSI Setup.
  2. Click the Discovery tab.
  3. Under Target Portals, click Add, and then specify the IP address and port of the iSCSI target portal. Click OK.
  4. Click the General tab, click Change, and then specify the name of any iSCSI initiator that is allowed access to the device.
  5. Click the Targets tab, click Refresh, select the iSCSI target from the list, and then click Connect. Click OK to connect to the iSCSI target.
  6. If CHAP authentication is enabled in the iSCSI target settings, you will see the Authentication Failure error. In this case, click Connect, click Advanced, select the Enable CHAP log on check box, and then specify the same user name and target secret as in the iSCSI target settings. Click OK to close the window, and then click OK to connect to the iSCSI target.
  7. Click OK to close the window.
