Fibre Channel

Fibre Channel is a TrueNAS Enterprise feature. Only TrueNAS systems licensed for Fibre Channel have the Fibre Channel Ports added to Sharing > Block Shares (iSCSI) screens.

Sharing ISCSI Fibre Channel Ports

Setting up a Fibre Channel ISCSI Share

This procedure uses an example to illustrate each step.
  1. Add a zvol to use for the share.

    a. Go to Storage > Pools.

    b. Find an existing pool, click   and Add zvol to create a new zvol.


  2. Configure these iSCSI tabs in Sharing > Block Shares (iSCSI):

    Initiators and Authorized Access screens only apply to iSCSI and can be ignored when configuring Fibre Channel.

    a. Portals. Check for the IP and port number. If it doesn’t exist, click Add and add this portal.

    b. Targets. Click Add to set up a new target. Enter the values for your uses case in the Target Name, Target Alias, and Portal Group.

    Select the Target Mode option from iSCSI, Fibre Channel or Both.

    The Initiator Group ID selects which existing initiator group has access to the target.

    Options for the Authentication Method are None, CHAP, or Mutual CHAP.

    Set Authentication Group Number to either none or an integer. This value represents the number of existing authorized accesses.

    The Target Reporting tab provides Fibre Channel port bandwidth graphs.

    c. Extents. Click Add to create a new extent.


    d. Associated Targets. Click Add to add a new associated target.

    Select values for Target and Extent.

    The LUN ID is a value between 0 and 1023. Some initiators expect a value below 256. Leave this field blank to automatically assign the next available ID.
