SAN provisioning with iSCSI

You should be aware of important concepts that are required to understand how ONTAP implements an iSCSI network.

  • iSCSI target node network connections and names
    iSCSI target nodes can connect to the network in several ways:
  • Storage system node name
    Each SVM running iSCSI has a default node name based on a reverse domain name and a unique encoding number.
  • TCP port for iSCSI
    The iSCSI protocol is configured in ONTAP to use TCP port number 3260.
  • iSCSI service management
    You can manage the availability of the iSCSI service on the iSCSI logical interfaces of the storage virtual machine (SVM) by using the vserver iscsi interface enable or vserver iscsi interface disable commands.
  • iSNS server registration requirement
    If you decide to use an iSNS service, you must ensure that your storage virtual machines (SVMs) are properly registered with an Internet Storage Name Service (iSNS) server.
