Creating an iSCSI Target

  1. Go to iSCSI & Fibre Channel > iSCSI Storage.
  2. Click Create, and then select New iSCSI Target.

    The iSCSI Target Creation Wizard window opens.

  3. Click Next.
  4. Specify a target name.

    QuTS hero appends the specified name to the iSCSI qualified name (IQN). IQNs are unique names used to identify targets and initiators.

    • Valid characters: 0 to 9, a to z, A to Z

    • Length: 1 to 16 characters

  5. Optional: Specify a target alias.

    An alias enables you to identify the target more easily on the initiator.

    • Length: 1 to 32 characters

    • Valid characters: 0 to 9, a to z, A to Z, underscore (_), hyphen (-), space ( )

  6. Optional: Select Allow clustered access to this target.

    When enabled, multiple iSCSI initiators can access this target and its LUNs simultaneously.

    Warning:

    To prevent data corruption, the initiators and LUN filesystems must all be cluster-aware.

  7. Optional: Enable CRC checksums.

    Initiators and targets communicate over TCP connections using iSCSI protocol data units (PDU). The sending device can send a checksum with each PDU. The receiving device uses this checksum to verify the integrity of the PDU, which is useful in unreliable network environments. There are two checksum types, which can be enabled separately.

    Checksum Type

    Description

    Data Digest

    The checksum can be used to verify the data portion of the PDU.

    Header Digest

    The checksum can be used to verify the header portion of the PDU.

  8. Click Next.
  9. Optional: Enable CHAP authentication.

    An initiator must authenticate with the target using the specified username and password. This provides security, as iSCSI initiators do not require a NAS username or password.

    • Username

      • Length: 1 to 127 characters

      • Valid characters: 0 to 9, a to z, A to Z, colon (:), period (.), hyphen (-)

    • Password

      • Length: 12 to 16 characters

      • Valid characters: 0 to 9, a to z, A to Z, all special characters

    Note:

    If you migrate your system to another NAS, you must configure the CHAP password again on the new NAS. You can reuse the old password or create a new password.

  10. Optional: Enable mutual CHAP authentication.

    Both the initiator and the target must authenticate with each other for additional security. First, the initiator authenticates with the target using the CHAP authentication username and password. Next, the target authenticates with the initiator using the mutual CHAP username and password.

    • Username

      • Length: 1 to 127 characters

      • Valid characters: 0 to 9, a to z, A to Z, colon (:), period (.), hyphen (-)

    • Password

      • Length: 12 to 16 characters

      • Valid characters: 0 to 9, a to z, A to Z, all special characters

    Note:

    If you migrate your system to another NAS, you must configure the mutual CHAP password again on the new NAS. You can reuse the old password or create a new password.

  11. Click Next.
  12. Optional: Select Create a LUN and map it to this target.

    If selected, QuTS hero opens the Block-Based LUN Creation Wizard immediately after finishing this wizard. The new LUN will then be automatically mapped to this target.

  13. Click Apply.

QuTS hero creates the iSCSI target, and then opens the Block-Based LUN Creation Wizard window if Create an iSCSI LUN and map it to this target was enabled.
